MCenter Control Room (MC-CR) x3726 or x8871
6 117 Jennifer Raaf
* Call the Main Control Room (x3721) at the start and at the end of shift. This is required, and pleasant.
7 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 
51 1 William Badgett
52 152 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.
53 152 Jason St. John
54 179 Jason St. John
h2. *Trouble getting started*
55 152 Jason St. John
56 205 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).
57 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.

h2. *Trigger and DAQ system*
60 152 Jason St. John
61 188 Jason St. John
When the DAQ crashes, please post the relevant information to [[DAQerrors]] for experts to study.
62 188 Jason St. John
63 187 Jason St. John
h3. Common failures:
64 187 Jason St. John
65 187 Jason St. John
* DAQ fails with @ERROR: ReadRegisgter ACQUISITION_STATUS CAEN_DGTZ_CommError BoardId 0@  wait 2 minutes, then try to start again.
66 187 Jason St. John
** 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.
68 187 Jason St. John
* DAQ fails with @Found persistent communication port still open@
69 187 Jason St. John
** Wait 8 minutes for the ports to clear, then try again.
70 187 Jason St. John
71 187 Jason St. John
h3. Other failures: 
72 187 Jason St. John
73 1 William Badgett
* 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.
74 187 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.
75 187 Jason St. John
* If the trigger crate has been power cycled and the V1495 is not emitting triggers: [[Reset1495]]
76 83 Jason St. John
77 152 Jason St. John
h2. *Wire Chambers*
78 152 Jason St. John
79 162 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.
80 135 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.
81 83 Jason St. John
82 172 Jason St. John
h2. Power Cycle the ASICs (TPC Wire Noise)
83 168 William Badgett
84 168 William Badgett
* Anecdotal evidence has shown that analog noise on the TPC wire readout channels can be 
85 169 William Badgett
alleviated by power cycling the TPC electronics: ASICs and Warm Receiver/Drivers
86 203 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 
87 173 William Badgett
second powerless interlude.
88 173 William Badgett
* Further important informations can be found on the white board in MC-CR.
89 168 William Badgett
* This mechanism is controlled by a smart power distribution unit (PDU) located under the 
90 168 William Badgett
TPC electronics power supply near the cryostat in the enclosure.   Due to electrical safety 
91 170 William Badgett
rules you must *NOT* use any of the other outlets on this PDU.  Do *NOT* remove the protective 
92 168 William Badgett
outlet covers at any time.

h2. Recover from a LAr level interlock
96 181 Jason St. John
97 182 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.

# Be sure HV is set to zero for these: Cathode Drift, Wire Bias, cryo-PMTs
100 183 Sarah Lockwitz
How to control the [[Drift HV]]
101 181 Jason St. John
# Power down the ASICs. (They should be off when TPC voltages change.)
102 181 Jason St. John
# Bring up the Cathode
