 09 Nov 2019 07:29, Marco Rescigno, Problem Fixed, MIDAS, this morning problem
|
frontend process still alive but slow, causing lot of rejected triggers.
stopped and restarted the feov1725 process to fix this |

03 Apr 2019 15:31, Thomas, Routine, Software, test of elog
|
| The last elog didn't go out cleanly. Modified the elogd.cfg to point to the proxy. Try again. |

16 Jul 2019 03:53, Marco Rescigno, Routine, General, run 774, scintillation events triggering on all 24 channels and 200 us window 
|
Majority of 8, threshold at 1000 ADC count, 24 channels enabled (16 trigger signals) 10 Hz, 200 us window, trigger at 9.5 microseconds.
10 k events recorded.
By direct inspection pileup seems at the 10 % level in the 200 us window. |
|
16 Jul 2019 03:51, Marco Rescigno, Routine, General, run 773, scintillation events triggering on all 24 channels
|
Majority of 5, threshold at 1000 ADC count, 24 channels enabled (16 trigger signals) 100 Hz, 30 us window.
38 k events recorded. |
|
16 Jul 2019 03:17, Marco Rescigno, Routine, General, run 772, scintillation events triggering on all channels
|
Majority of 5, threshold at 1000 ADC count, 13 channels enabled (10 trigger signals) 50 Hz, 30 us window.
58 k events recorded. |
|
16 Jul 2019 02:39, Marco Rescigno, Routine, General, run 771, scintillation events triggering on ch11 and ch12 of board0
|
Trigger setup with a threshold of 1500 ADC count wrt to baseline, on just two channels.
This is also to limit the trigger to 50 Hz, since the busy still did not work.
100 K events on disk. |

Run 956
Gas pocket: ON (thickness 7mm)
Fields: drift 200 V/cm, extraction 2.8 kV/cm |
|
07 Nov 2019 23:48, Yi Wang, Routine, General, morning data taking
|
Run 973
Gas pocket: ON (thinkness 7mm)
Fields: drift 200 V/cm, extraction 3.78 kV/cm |

11 Jul 2019 15:52, Thomas, Routine, Trigger, invert first chronobox busy signal
|
The DAQ seems to be ready for tests with proto-0 tomorrow.
I had to invert the first busy input in order to get chronobox to produce triggers. I modified the setup script
