Thu Feb 6 00:45:25 2020, Dinko Ferencek, Cold box tests, Lost at least one Peltier in the coldbox
|
During an overnight (Feb. 4-5) FullQualification run with modules 1545, 1547, 1548, and 1549 the coldbox lost the ability to maintain the temperature at
-20 C. As can be seen from the attached temperature log, the problems already started during the temperature cycles where the last 2 cycles were noticeably
longer than the first 3 and finally during the second Fulltests at -20 C the temperature started rising and stabilized around -10 C. Based on these observations |
 Thu Feb 6 17:28:23 2020, Dinko Ferencek, Cold box tests, New Peltiers installed
|
Today new Peltiers were installed and tested. Unfortunately, we had trouble reaching -20 C with this new set of Peltiers (they are of different type than
the ones that were taken out). After better insulation ofthe sample compartment and lowering the chiller temperature from 11 to 6 C, the coldbox was able
to reach close to -19.8 C after about half an hour

Thu Feb 6 17:09:50 2020, Dinko Ferencek, Module assembly, Gluing stamp improvements
|
Silvan has made additional grooves on the gluing stamp which now sits stably on top of the module without any rocking motion and also allows better glue
distribution to all the HDI components that are supposed to receive the glue. |

Wed Feb 5 16:18:30 2020, Dinko Ferencek, Module transfer, Module location tracking added to the assembly spreadsheet
|
To keep track of the module location, two columns were added to the module assembly spreadsheet [URL=https://docs.google.com/spreadsheets/d/12m2ESCLPH5AyWuuYV4KV1c5O_NEy7uP5PQKzVsdr3wQ/edit?usp=sharing]https://docs.google.com/spreadsheets/d/12m2ESCLPH5AyWuuYV4KV1c5O_NEy7uP5PQKzVsdr3wQ/edit?usp=sharing[/URL]
that contain the dates when a given module is shipped to ETHZ and when it is returned to PSI. |
|
Wed Feb 5 16:07:03 2020, Dinko Ferencek, Module assembly, Module assembly spreadsheet migrated to Google Sheets
|
Excel file stored on CERNBox containing the module assembly spreadsheet has been replaced with a Google Sheet [URL=https://docs.google.com/spreadsheets/d/12m2ESCLPH5AyWuuYV4KV1c5O_NEy7uP5PQKzVsdr3wQ/edit?usp=sharing]https://docs.google.com/spreadsheets/d/12m2ESCLPH5AyWuuYV4KV1c5O_NEy7uP5PQKzVsdr3wQ/edit?usp=sharing[/URL].
This change should make common editing of the spreadsheet easier.

Today I continued where Matej left off with commissioning the blue coldbox setup for reception tests. All the necessary software (pXar and elComandante)
Matej already installed (just had to add the BB2 section in testParameters.dat). What was a problem in communication with Keithley (Model 2400) which was
fixed after changing the BAUD rate in elComandante/keithleyClient/keithleyInterface.py to 19200 (value set in Keithley's communications settings) and changing |

|
During the first fulltest@-20 of the full qualification procedure for modules: 1539, 1541, 1542 and 1543; an error message popped up "psi Agente: self.Testboards[0]
failed - the following boards are busy: TB1(DTB...:M1541), TB2(DTB...:M1542), TB3(DTB...:M1543). This means that the first fulltest for module 1539 was
not executed.

Mon Jan 27 17:50:48 2020, Matej Roguljic, Cold box tests, Failing modules at -20
|
Friday, 24.1., it was noticed that the modules are graded as 'C' in similar fashion. Module is graded A/B at +10 degrees and then graded C at -20. The reason
for grade C was that the trimming procedure was not successful on at least one of the ROCs on each module. This problem was further investigated on 27.1.
Wolfram suspected that the problem lies in zero suppression mode since the pixels with failed threshold comes in groups of four pixels. The corresponding |
