Meeting note (Dionisio)
ePixM
beam time scheduled for Run23
Labor Day weekend MFX
Plus a Science measurements at Rixs
Tasks to be done below
Bias voltage setting
Who:
Just need to find out the correct bias and this should be very minimal of non existent. -50V vs -110V
What to do:
Get working carrier
Perform measurements starting from -50V and going to -110V and come up proper valueSecond question
Can we reliably work at -110V for long periods of time?
Dead pixels
Who: Zongde
Map of 0 gain
Map of low gain
Check if the number of them changes with time
What to do
Generate maps from existing data
Missing lanes
Who: Dawood
Why do we have so many missing lanes per ASIC
Electrical measurements
Cross talk
Who: Bahvna
In the lab use mask and check fro cross talk with
Linearity analyses (sti)Software
Who:
Do we have all the modules that are needed to make the analysis
Charge injection analyses
Firmware
Who: Dawood
Charge injection
Hardware
Who: Xavier
Getting new modules in the existing detectors
Charge Injection
Who: Xavier/Philip
From Lorenzo how do we do set the charge injection (how many columns)
Philip needs a dataset from rogue to make the analyses
Definition of science grade measurements
Charge Injection
Blue light
Single photons
Intensity scan
List of analyses/tools document
Who: Philip/Nolan
Status
First experiment
Direct beam ~2mm
Changes in intensity
How to calibrate lab vs beam
Spent beam lab
Who: Alex
Status
OIP requested
Sequence of tasks
1 - New module at ASC
2 - Bias level
3 - charge injection
4 - crosstalk
5 - List and status of analyses
6 - DAQ support (check that the database is available at the DAQ software) (WHO:zongde)
