* Call the Main Control Room (x3721) at the start and at the end of shift. This is required, and pleasant.

* If the beam goes away for more than a few spills, look for Accelerator Alarms in ACNET (a default window). If the problem persists a few minutes, and you see nothing about it in the MCR elog, (or you just really want to find out more), call the MCR.  They're friendly, though they may be super-busy.

h2. *Trouble getting started*
54 152 Jason St. John
55 205 Luke Batten
* If you cannot ssh to FTBFLX machines: Get a kerberos ticket for yourself: @kinit <yourKerberosPrincipal>@, then ssh ftbf_user@ftbflx18 (or ssh ftbf_user@ftbflx15 or ssh ftbf_user@ftbf-cr-03).
56 216 Luke Batten
* If your Kerberos username and password are good, but you can't log on to FTBFLX[NN] machines:  Have someone who CAN log into those machines check that your kerberos principal appears in @~ftbf_user/.k5login@ in the LArIAT section (email the Run Co-ordinator at stjohn@fnal.gov). 
57 216 Luke Batten
* The same ssh errors may also apply to computers at ROC West. Troubleshoot using the above methods.

** Try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.
67 187 Jason St. John
This command is appropriate when one sees any type of "CAEN_DGTZ" error.  This command will NOT help the persistent ports error.

* DAQ fails with "An exception occurred when trying to send a message to ..." 
71 223 Pawel Kryczynski
** Check that the terminal you are running the DAQ from is indeed lariat-daq00 (or a screen within it).  Output from @klist@ should show the default principal as "lariat/lariat/lariat-cr-02.fnal.gov@FNAL.GOV" or similar if running from a screen off lariat-daq00 from the ROC-West station.

82 135 Jason St. John
* If the wire chamber system is skipping spill numbers, it may be a high trigger rate (> 30 k per spill).  The wire chamber controller may still be reading out the hits from the last spill.

* Anecdotal evidence has shown that analog noise on the TPC wire readout channels can be

alleviated by power cycling the TPC electronics: ASICs and Warm Receiver/Drivers
88 203 Will Foreman
* You can remotely power cycle the TPC electronics.  Log onto lariat-gateway00.fnal.gov with X-forwarding enabled, type "firefox", and go to http://lariat-pdu02.fnal.gov.  Usename "ftbf" (password posted on whiteboard in MC7).  Choose the *CYCLE* option, which will automatically give a 60

* This mechanism is controlled by a smart power distribution unit (PDU) located under the 
92 168 William Badgett
TPC electronics power supply near the cryostat in the enclosure.   Due to electrical safety 
93 170 William Badgett
rules you must *NOT* use any of the other outlets on this PDU.  Do *NOT* remove the protective

* The readback voltage doesn't make any sense, is of the wrong polarity and/or is way above the nominal value, but just for a fraction of time.
116 220 Flor de maria Blaszczyk
This is most likely just a glitch in the readout, please ignore if it happens once or twice. If it happens too frequently, set voltage to 0, turn off the power supply and report it. 
117 219 Flor de maria Blaszczyk
118 220 Flor de maria Blaszczyk
* The readback voltage doesn't make any sense, is of the wrong polarity and is way above the nominal value, and the value is stable~ish (you might see small fluctuations over time)
119 220 Flor de maria Blaszczyk
This is a typical symptom of a bad power supply. Try to set it back to 0, turn it off and disconnect the SHV cable. If the readout values remain the same, it confirms there is a hardware problem. Please contact Brian Fellenz for repairs if we don't have a spare for that unit.
120 1 William Badgett
121 220 Flor de maria Blaszczyk
FYI, the power supplies have a given voltage rating and cannot physically deliver voltages beyond that range. Also, their polarities cannot be swapped so if you see the wrong sign on the readout ie a positive voltage on a negative power supply or vice versa, then you can be sure the unit is broken or you have a problem somewhere else in the system.
122 221 Flor de maria Blaszczyk
- Bias voltage rating: - 500 V for the shield and induction planes, + 500 V for the collection plane.
123 221 Flor de maria Blaszczyk
- ELT and Hamamatsu PMTs: +2000 V
124 221 Flor de maria Blaszczyk
- All of the other units: -2000 V

126 219 Flor de maria Blaszczyk
* Something went wrong during a ramp, I need to turn off the supply!
127 220 Flor de maria Blaszczyk
There is an interlock that prevents you from using the normal fast controls on the power supply when a ramp is on-going. First, *stop the ramp by clicking on the STOP button*. This will stop the ramp and clear the interlock. If you need to go back to 0 quickly, use the fast controls to set the voltage to 0 and *don't forget to turn off the supply!*
128 219 Flor de maria Blaszczyk
129 221 Flor de maria Blaszczyk
*Even if the controls appear not to respond, set the voltage to 0 and turn the supply off*. Contact Charlie Briegel first and describe the problem in detail. If you can and if it's safe, disconnect the SHV cable from the power supply. If the readback values remain the same, then the power supply is broken.
