Runs 26184022-28 were plagued with TPC Anode HV trips, particularly (Sector 4, Channel 5) and (Sector 20, Channel 5). Also faced several iTPC RDO trips, particularly (Sector 13, RDO 3). These runs are marked as bad.
Set HV for TPC (Sector 4, Channel 5) to 1345V, masked out iTPC (Sector 13, RDO 30 on Tonko's advice. Alexei increased (Sector 20, Channel 5)'s trip level from 2uA to 4uA. There has been no trips since.

-
iS22-4 masked in high rate running because it was giving us issues
-
take a better look in the logs at e.g. run 26182028, 29
-
PROM?
-
reburned just in case but still issues? Probably power, damn.
-
-
yes, power, voltage is 3.2V on input which is at the very edge
-
perhaps kill a few FEEs???
-
stays masked

iS05-1 masked (PROM?)
-
hm, looked OK but reburning just in case…
-
reburned, try
-
should unmask after the test
-
-
IS21-2 masked
-
FEE PROM?
-
reburned, try
-
should unmask after the test
-
-
iS06-2 masked – PROM?
-
yes, reburned
-
should unmask
-
-
iS04-2 failed prom-check but I need more time
-
reburned
-
-
iS22-3 failed prom-check, ibid

iS13-2 masked – PROM?
-
yes, but the master image? But then it recovers??
-
will stay masked until I get more time…
-
reburned image 0 and 1
-
should unmask after the test

-
iS11-2 auto-recovers a lot, from day 1
-
generally flaky FEE connection, on most FEEs
-
-
-
Jun 27
-
iS03-3-FEE#2 first 32 channels (1 SAMPA) look noisy
-
monitor it…
-
masked FEE
-
-
iS02-2 – PROM
-
reburned – looks OK
-
should unmask
-
-
iS03-1
-
configures but I need to see it running
-
bad in running; FEE #6 masked so let’s see; lppks OK
-
-
iS03-3
-
configures but I need to see it running
-
bad in running; FEE #10 masked so let’s see; looks OK
-
-
iS04-1 flaky since day 1
-
configures but this is the problematic RDO with likely power issues
-
stays masked?
-
bad while running; but OK with empty events
-
unmask for a test
-
-
1S10-3 masked; suspect PROM
-
yup, PROM – reburning…
-
unmasked
-
-
iS17-4 – nasty, no FEEs respond – power? a2?
-
PROM
-
reburned – should unmask
-
-
iS18-1 – looks like power but I need to check more
-
no FEEs succeed for many attempts but sometimes they do??
-
reburned I1 and I2 PROM and now looks OK
-
should unmask
-
nope, bad again
-
on 2nd look: many FEEs don’t boot… but not all, and they change so some power issue?
-
looks OK again, unmask
-
-
iS19-2 – no FEEs respond – power? a2?
-
PROM
-
reburned – should unmask
-
-
iS24-4 OLD; stays masked
-
also has bad tokens and trg_cmd so mask it forever
Jun 16-
iS05-3 masked
-
FEE #1 masked
-
RDO unmasked
Jun 15 (AuAu 4kHz rate)
-
-
TPX S01-4 masked
-
there seem to be 2 iffy FEEs, even from last year – masked them
-
let’s unmask the RDO
-
-
iS09-3 masked
-
flaky. Looks like FEE #6. But keep masked until I get time.
-
should unmask RDO at re-test
-
-
Flaky
