MCenter Control Room (MC-CR) x3726 or x8871

* Call the Main Control Room (x3721) at the start and at the end of shift. This is required, and pleasant.
6 69 Jason St. John
* 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.

h1. Troubleshooting 
44 1 William Badgett
45 152 Jason St. John
Any time day or night, please call experts if you are in need of help and the answer is not provided below.
46 152 Jason St. John
47 179 Jason St. John
h2. *Trouble getting started*
48 152 Jason St. John
49 146 Jason St. John
* If you cannot ssh to FTBFLX machines: Get a kerberos ticket for yourself: @kinit <yourKerberosPrincipal>@, then ssh ftbf_user@ftbflx01 (or whichever machine...).
50 1 William Badgett
* 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 heck that your kerberos principal appears in @~ftbf_user/.k5login@ in the LArIAT section.
51 1 William Badgett
52 152 Jason St. John
h2. *Trigger and DAQ system*
53 152 Jason St. John
54 180 Jason St. John
* If the DAQ is having trouble talking to the crates, try issuing the command @lariatReset 0 1@ waiting more then 5 seconds, and trying again.
55 1 William Badgett
* If the trigger crate has been power cycled and the V1495 is not emitting triggers: [[Reset1495]]
56 161 Jason St. John
* If the DAQ cannot initialize, and you suspect the configuration XML files were changed recently, check their formatting. [[XML Checker]]
57 178 Will Flanagan
* When the DAQ crashes, please post the relevant information to [[DAQerrors]] for experts to study.
58 83 Jason St. John
59 152 Jason St. John
h2. *Wire Chambers*
60 152 Jason St. John
61 162 Jason St. John
* If the wire chambers are acting strangely: "remote power cycling instructions":https://redmine.fnal.gov/redmine/projects/lariat-online/wiki/Communicating_with_the_wire_chambers including mini-DAQ and telnet interface.
62 135 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.

64 172 Jason St. John
h2. Power Cycle the ASICs (TPC Wire Noise)
65 168 William Badgett
66 168 William Badgett
* Anecdotal evidence has shown that analog noise on the TPC wire readout channels can be 
67 169 William Badgett
alleviated by power cycling the TPC electronics: ASICs and Warm Receiver/Drivers
68 172 Jason St. John
* You can remotely power cycle the TPC electronics via the web site http://lariat-pdu02.fnal.gov 
69 173 William Badgett
logging in as user "ftbf".  Choose the *CYCLE* option, which will automatically give a 60 
70 173 William Badgett
second powerless interlude.
71 173 William Badgett
* Further important informations can be found on the white board in MC-CR.
72 168 William Badgett
* This mechanism is controlled by a smart power distribution unit (PDU) located under the 
73 168 William Badgett
TPC electronics power supply near the cryostat in the enclosure.   Due to electrical safety 
74 170 William Badgett
rules you must *NOT* use any of the other outlets on this PDU.  Do *NOT* remove the protective 
75 168 William Badgett
outlet covers at any time.

h2. Recover from a LAr level interlock
79 181 Jason St. John
80 182 Jason St. John
Assuming the LAr Level dropped low enough to trip off the TPC Cathode power supply, and maybe you even powered down the PMTs.
81 182 Jason St. John
82 181 Jason St. John
# Be sure HV is set to zero for these: Cathode Drift, Wire Bias, cryo-PMTs
83 181 Jason St. John
# Power down the ASICs. (They should be off when TPC voltages change.)
84 181 Jason St. John
# Bring up the Cathode
85 181 Jason St. John
# Bring up the Wire Bias
86 181 Jason St. John
# Bring up the ASICs
87 181 Jason St. John
# Bring up the PMTs
