41 | 52 | Flor de maria Blaszczyk | * Click inside any of the frames (mouse-over until you get a small hand for a pointer) for each sub-system part to open the history plots for the corresponding devices. |
42 | 52 | Flor de maria Blaszczyk | * The small gears on the top right corner inside the frames open the control panels when controls are available. |
43 | 52 | Flor de maria Blaszczyk | * Red boxes will appear to indicate a value is out of the allowed range. |
44 | 52 | Flor de maria Blaszczyk | * On top of the cryostat drawing, you might get alarm messages such as LAr dewar level too low, HV interlock or cryostat LAr level too low. Please pay attention to these. |
45 | 1 | Flor de maria Blaszczyk | |
46 | 52 | Flor de maria Blaszczyk | * Click on the cryostat drawing to open the cryogenic system overview. |
47 | 52 | Flor de maria Blaszczyk | * Click on the TPC drawing to open the TPC overview. |
48 | 1 | Flor de maria Blaszczyk | |
49 | 1 | Flor de maria Blaszczyk | *Beam related information* |
50 | 1 | Flor de maria Blaszczyk | * MC6CV indicates the opening a vertical collimator in the secondary beamline(see "Switchyard Layout":https://cdcvs.fnal.gov/redmine/attachments/download/23879/Switchyard-Current.pdf ). When the beam profiles do not look “good” (off-centered or too wide), MCR can change this value to improve the beam profile. |
51 | 1 | Flor de maria Blaszczyk | * MCENRG states the energy of the secondary beam at the LArIAT target. |
52 | 1 | Flor de maria Blaszczyk | |
53 | 1 | Flor de maria Blaszczyk | *Tertiary magnets* |
54 | 1 | Flor de maria Blaszczyk | * MC7AT1 states the temperature of the coil of magnet 1. Alarm above 175º F. |
55 | 1 | Flor de maria Blaszczyk | * MC7AT2 states the temperature of the coil of magnet 2. Alarm above 175º F. |
56 | 22 | Flor de maria Blaszczyk | * +MC7AN+ is the current of the magnets . +Remember to report this number when starting a run+. |
57 | 1 | Flor de maria Blaszczyk | * MC7ANB is a probe inserted in our magnets to measure the polarity of the field. The actual value stated is not important as only the sign matters. +Double check that the polarity is the right one (positive or negative)+ required for the run and +remember to report its value in the elog when starting a run+. |
58 | 2 | Flor de maria Blaszczyk | |
59 | 20 | Flor de maria Blaszczyk | *Scintillator counters* |
60 | 2 | Flor de maria Blaszczyk | * MC7SC1 states the number of counts for the scintillator counter before the LArIAT target. Intensity of the secondary beam. 1E5 or more is pretty good. |
61 | 8 | Flor de maria Blaszczyk | * MC7SC2 states the number of counts for the scintillator counters after the last magnet. |
62 | 1 | Flor de maria Blaszczyk | * MC7SC3 states the number of counts for the scintillator counters after the Wire Chamber 4. |

107 | 52 | Flor de maria Blaszczyk | * The level meter inside the LAr dewar does not cover the full range of the dewar. The maximum reading is 72"Ar which represent ~ 79% full. When there is a refill, the value should read 79% for a while, until the level reached the active range of the instrument. |
108 | 52 | Flor de maria Blaszczyk | * An alarm will be triggered when the LAr dewar level drops below 30%. |

112 | 1 | Flor de maria Blaszczyk | h1. 4) For experts: Synoptic power supplies controls |
113 | 1 | Flor de maria Blaszczyk | |
114 | 63 | Flor de maria Blaszczyk | These instructions apply to the power supplies for the wire chambers, the bias voltage, the cryo PMTs, some of the muon range stack paddles, halo veto. |
115 | 12 | Flor de maria Blaszczyk | Before you do anything... some useful information: |
116 | 1 | Flor de maria Blaszczyk | |
117 | 12 | Flor de maria Blaszczyk | * *Settings are disabled by default.* This means you can zoom in / out on the plots or click on the links but cannot change any setting. |
118 | 1 | Flor de maria Blaszczyk | |
119 | 25 | Flor de maria Blaszczyk | * *Closing a window restarts the plots, but the settings are NOT changed.* This means that if you close a window (on purpose or by mistake) or if the display crashes (it can happen from time to time) the power supply remains in whichever state it was before the closure. If it was on, it remains on at whatever voltage it was set. |
120 | 1 | Flor de maria Blaszczyk | |
121 | 12 | Flor de maria Blaszczyk | * *To power off a supply, please set the voltage to 0 first and then turn it off. Do not forget to turn it off!* |
122 | 60 | Flor de maria Blaszczyk | |
123 | 51 | Flor de maria Blaszczyk | * *If a VME PS has to be turned off in an emergency situation (e.g. problem with TPC PMTs) - turn off the regulate function first, then +put the decreasing voltage values in the quick ramp window, go to 0 and then turn off!+* |
124 | 1 | Flor de maria Blaszczyk | |
125 | 62 | Flor de maria Blaszczyk | !>MWPCHV_animated.gif! |
126 | 62 | Flor de maria Blaszczyk | 1) To enable settings, click on the button on the bottom right hand corner. |
127 | 62 | Flor de maria Blaszczyk | 2) Select for how long you wish to enable the settings (Disable, 10mn, 1h or 8h). Do not forget to disable the settings once you are done! |
128 | 1 | Flor de maria Blaszczyk | |
129 | 62 | Flor de maria Blaszczyk | _There are pop-up confirmation windows that will prevent you from changing anything by mistake but it is still better to disable the settings once you have finished._ |
130 | 1 | Flor de maria Blaszczyk | |
131 | 62 | Flor de maria Blaszczyk | 3) To turn on / off an power supply, click on the on / off button. A window will pop-up for confirmation. When the supply is on, the light should be green. |
132 | 1 | Flor de maria Blaszczyk | |
133 | 62 | Flor de maria Blaszczyk | 4a) Turn off the regulate function if it's on (the light is dark red when off, green otherwise). |
134 | 1 | Flor de maria Blaszczyk | |
135 | 63 | Flor de maria Blaszczyk | 4b) Set the nominal voltage *in the RAMP frame* by clicking on the bright button next to the power supply you would like to set a voltage to. A window will pop up, enter the value *including the "-" sign* and validate (hitting the enter key doesn't work). If you enter a positive value and the supply is negative only, or if you enter a value out of range, nothing will happen. You will have to re-enter a value. |
136 | 1 | Flor de maria Blaszczyk | |
137 | 63 | Flor de maria Blaszczyk | *WAIT until the readout value has stabilized and is around the nominal value you set.* |
138 | 1 | Flor de maria Blaszczyk | * FYI, ramp times from 0 to nominal: ~ 2mn for the wire chambers, ~2h for the cryo PMTs, ~2mn for the bias voltage |
139 | 63 | Flor de maria Blaszczyk | * You can stop the ramp at anytime by clicking on the stop button. |
140 | 1 | Flor de maria Blaszczyk | |
141 | 63 | Flor de maria Blaszczyk | %{color:red}Keep an eye on the current draw when ramping up the wire chambers. If current > 10 uA, the power supply will trip. Repeat from step 3.% |
142 | 1 | Flor de maria Blaszczyk | |
143 | 63 | Flor de maria Blaszczyk | There will be an offset between the readout and the setting, you can fine tune as follows. |
144 | 63 | Flor de maria Blaszczyk | |
145 | 1 | Flor de maria Blaszczyk | 5a) Turn on regulate (light should be green when on). |
146 | 1 | Flor de maria Blaszczyk | |
147 | 63 | Flor de maria Blaszczyk | 5b) Set the nominal voltage (again) *in the quick settings frame* by clicking on the bright button. Wait for ~30s-1mn until the voltage stabilizes. |
148 | 1 | Flor de maria Blaszczyk | |
149 | 51 | Flor de maria Blaszczyk | 6) Check if the readout value matches what you were expecting within < 10V. |

154 | 67 | Flor de maria Blaszczyk | |
155 | 62 | Flor de maria Blaszczyk | Notes: |
156 | 62 | Flor de maria Blaszczyk | * Current can be readout in the bottom left hand side of the display. The top plot shows the voltage as a function of time, the bottom plot is the current as a function of time. |
157 | 62 | Flor de maria Blaszczyk | * When regulate is off, there is an offset between the value you set and the actual readout. The lower the voltage you set (with respect to the range of the PS, ie 0-2kV or 0-500V), the larger the offset. |
158 | 62 | Flor de maria Blaszczyk | * In particular, *for the induction plane bias, set a value of ~ 36-38 V to get 18V on the output*. Do not use regulate for this value, it will not work. |
159 | 62 | Flor de maria Blaszczyk | * The VME power supplies are not stable below a certain a value: for the 0-2kV ones (all PMTs, including cryo ones), do not set voltages below 200V; for the 0-500V (bias PS), do not set values below 36V (which will give you an 18V output). |

161 | 1 | Flor de maria Blaszczyk | h1. 5) For experts: Controlling the power supplies with ACNET |
162 | 1 | Flor de maria Blaszczyk | |
163 | 1 | Flor de maria Blaszczyk | *Please use this method ONLY if the Synoptic displays are not working even after restarting the Synoptic Viewer* (and contact F. Blaszczyk to report the issue). Once ACNET settings permissions are enabled, it is very easy to make mistakes: there is no confirmation window so you could cause a power supply to turn off or trip if you are not familiar with ACNET. |

167 | 1 | Flor de maria Blaszczyk | h1. Troubleshooting |
168 | 14 | Flor de maria Blaszczyk | |
169 | 1 | Flor de maria Blaszczyk | If Synoptic crashes or hangs up, do not panic! Only the application is affected, not the devices themselves. You only need to close the application and restart it. The non-historical plots will be reset. |
170 | 30 | Flor de maria Blaszczyk | |
171 | 27 | Flor de maria Blaszczyk | *The most common reasons why the Synoptic viewer does not start, crashes or gives you random errors are:* |
172 | 58 | Flor de maria Blaszczyk | |
173 | 1 | Flor de maria Blaszczyk | * You are not opening Synoptic correctly, i.e. you forgot to get a Kerberos ticket or you didn't open Synoptic with the script (or through the ACNET console) when working on a control room desktop computer. Please read the instructions carefully. |
174 | 58 | Flor de maria Blaszczyk | |
175 | 13 | Flor de maria Blaszczyk | * From your personal computer: you don't have the right Java environment. Make sure you have the "Sun / Oracle Java Runtime Environment (JRE)":http://www.oracle.com/technetwork/java/javase/downloads/index.html installed and up-to-date. OpenJRE / IcedTea does not seem to work well with Synoptic (unless you're lucky). |
176 | 58 | Flor de maria Blaszczyk | |
177 | 30 | Flor de maria Blaszczyk | * From your personal computer: your Java security parameters are not configured correctly. Because of some recent changes on the Java platform, you might have to do some tweaks to the Java security parameters. If you get an error that says that the application cannot be launched because it is from an unknown source / signature, please do the following: |
178 | 1 | Flor de maria Blaszczyk | |
179 | 1 | Flor de maria Blaszczyk | 1) Open the Java control panel. How to access it varies according to the OS (Google is your friend). You might have to launch it with admin privileges. |
180 | 1 | Flor de maria Blaszczyk | |
181 | 1 | Flor de maria Blaszczyk | 2) Select the security tab. |
182 | 1 | Flor de maria Blaszczyk | |
183 | 1 | Flor de maria Blaszczyk | 3) Drop the security to medium level. |
184 | 1 | Flor de maria Blaszczyk | *Note: This might not be possible in recent java versions. If you only have the high and very high options, choose high. |
185 | 1 | Flor de maria Blaszczyk | |
186 | 1 | Flor de maria Blaszczyk | 4) Add the following links to the exceptions list: |
187 | 1 | Flor de maria Blaszczyk | http://synoptic.fnal.gov |
188 | 1 | Flor de maria Blaszczyk | http://www-bd.fnal.gov |
189 | 31 | Flor de maria Blaszczyk | |
190 | 1 | Flor de maria Blaszczyk | 5) Validate. You might have to restart the computer for these changes to take effect. _Note: Make sure you type "http" and not "https". The latter will not work._ |
191 | 30 | Flor de maria Blaszczyk | |
192 | 30 | Flor de maria Blaszczyk | |
193 | 30 | Flor de maria Blaszczyk | *The most common reasons why you cannot do settings are:* |
194 | 30 | Flor de maria Blaszczyk | |
195 | 30 | Flor de maria Blaszczyk | * You forgot to enable the settings or you went past the time the settings were enabled. |
196 | 30 | Flor de maria Blaszczyk | |
197 | 30 | Flor de maria Blaszczyk | * There are no possible settings on the display (monitor only plots). |
198 | 35 | Flor de maria Blaszczyk | |
199 | 34 | Flor de maria Blaszczyk | * You are not including the "-" sign in front of the value you are trying to set. All the negative VME power supplies require you to include the sign, while the Glassman does not. |
200 | 36 | Flor de maria Blaszczyk | |
201 | 36 | Flor de maria Blaszczyk | * You are trying to set a value larger than the allowed limit. For security reasons or physical reasons (maximum PS voltage), some settings have been restricted to a particular range. |
202 | 30 | Flor de maria Blaszczyk | |
203 | 30 | Flor de maria Blaszczyk | * Your Kerberos account has not been granted setting permissions. There is only a few people who have settings permissions on their individual accounts. If you really need to do settings, all desktop computers in the control room can do settings, provided you started Synoptic correctly. |
204 | 30 | Flor de maria Blaszczyk | |
205 | 30 | Flor de maria Blaszczyk | * You are off-site. Even if you follow the procedure, and even if you're connected using the Fermilab VPN, you will not be able to enable settings. |
206 | 37 | Flor de maria Blaszczyk | |
207 | 33 | Flor de maria Blaszczyk | * We (as in LArIAT users) do not have settings permissions for that particular device. This shouldn't happen since all the devices used on Synoptic are LArIAT devices so we should have permissions for all of them. If it does happen, the device might be a recent one so we haven't been granted permissions yet. Please let Flor Blaszczyk and Charlie Briegel know. If you are doing settings on ACNET, make sure it is one of our devices and refrain from trying to change other devices (unless you are 100% sure you should). |
208 | 30 | Flor de maria Blaszczyk | |
209 | 30 | Flor de maria Blaszczyk | *Common web-viewer issues:* |
210 | 30 | Flor de maria Blaszczyk | |
211 | 1 | Flor de maria Blaszczyk | * "I know the device is on, why does it show as if it were off?" Because of Fermilab firewalls or your respective institution firewalls, it might take couple minutes for the displays to show up. If you see little "stars" instead of values with a unit in the readout sections of the displays and that nothing shows on the time plots, it means you're not getting any information from the devices. Only way to go around or speed things up: use the Fermilab VPN. |
