|
This morning I installed the xrootd-client and python3-devel packages from yum. For the latter to work, I needed to do a yum update. This was long overdue,
and updated 1200+ packages.

01 Nov 2019 06:15, Ben Smith, Problem Fixed, Software, Restoration of elog
|
After booting, the elog was only showing logs from before July, and was missing the "For Shifters" category. It appears we were loading the incorrect config
file. The running command was:

01 Nov 2019 06:07, Ben Smith, Problem Fixed, Software, Restoration of network settings
|
For a few days we were unable to access ds-proto-daq remotely. We were also unable to reach the outside world from ds-proto-daq.
To gain more control over the network settings, I have disabled the automatic configuration by dracut. I created the file /etc/dracut.conf.d/no-ifcfg.conf |
28 Oct 2019 15:10, Simone Stracka, Configuration, Hardware, LV for steering module and current status of CAEN mainframe 
|
The HV board from Naples did not turn on: Yury gave it to the CAEN guys to check and/or bring back for replacement.
Yi and Luigi rented a new HV module (A1519). The HV module (A1520P) we used for tests of the I-V script is also present in the Mainframe (see
below). |

28 Oct 2019 14:56, Simone Stracka, Problem, Software, Issues with network configuration for steering module
|
We have tried to connect the steering module to the DAQ pc via Luigi's USB-Ethernet adapter.
That does not appear to work. We'll receive another USB-Ethernet adapter tomorrow, and it should be configured to have a static IP address
: 192.168.121.1 and NetMask 255.255.255.0 |

27 Oct 2019 06:08, Simone Stracka, Configuration, Hardware, Converters installed in VME crate
|
People: Edgar, Simone
Installed differential to single-ended converters in VME crate, and turned crate back on. elog:47/2
Channel count in the converters is 0 to 15 starting from the low end. Wired according to: |

|
> V1725 board #0 logic level is set to TTL (boards #1, #2, #3 to NIM)
There was a problem with CMakeLists for the V1725 driver, and the frontend was only connecting to 1 board. This is now fixed, and all the boards should |

28 Oct 2019 06:28, Simone Stracka, Problem, Software, Need python3 package tkinter on DAQ pc
|
We need python3 package tkinter installed on ds-proto-daq in order to run the steering module GUI.
I don't have root privileges.

28 Oct 2019 08:33, Ben Smith, Problem Fixed, Software, Need python3 package tkinter on DAQ pc
|
| I have installed the python3-tkinter package from yum. I checked that "import tkinter" works from a python3 prompt. |

26 Oct 2019 07:33, Sam Hill, Problem, Software, Test of IV Script
|
People: Simone, Sam, Tom, Edgar
Tested IV curve python script that runs using MIDAS. Measured resistance consistant with resistor specification. elog:46/1
The resistance is attached to ch11, and we called the script (channels go from 0 to 24): |

|
Crew: Edgar Sanchez Garcia, Sam Hill, Simone Stracka, Tom Thorpe, Yi Wang
Morning: Set up equipment for the IV curve measurements. We enable the interlock system in the SMU in order to go higher than 42 V (handle with care).

25 Oct 2019 07:17, Simone Stracka, Routine, Hardware, Photoelectronics activities on October, 24
|
Crew: Edgar Sanchez Garcia, Sam Hill, Simone Stracka, Tom Thorpe, Yi Wang
Morning: Tested photocurrents for MB2 on tabletop using SMU and Keithley switching matrix. All measured between 1-10 microAmps.
Afternoon: Tested PDU mounting procedure with TPC assembled and with the mockup. No showstoppers. This will be the procedure for installation |

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. |
