EC test for SoLID
Preparation
- DAQ
Hardware: Done! VME based: CPU(VxWorks) + TI + 2V792 + NIM modules ---> can handle 64 channels
Software: CODA 2.6.2 is already installed, and configuration is done!
To do:
An issue in boot script need to be fixed, Alex and I are working on it.
Readout list(based on v792) should be modified to feed our needs, I am working on it
- 2D table: done!
It can be operated interactively through serial connectors.
- MaPMT related issues:
Yi is asking Carl for a H8500
Cable to connect H8500 and V792, need to make new ones???
H8500--->Socket: "SQT-118-01-L-D SAMTEC"; 2 rows, 18*2 pins, 16 pins for signal, 1 of no use, others are GND
V792---> Socket for "3431-5202 Header-type male connectors"; 17*2 pins, 16 pins for singal, 1 of no use, others are GND
- Black Box:
Need a box which can host 2D motional table(rough size of table:50cm X 50cm X 50cm), build a new one???
- LED related issues:
I have a LED controller on hand(from Alex), it is part of a integrated LED system,
where is the LED part, Alex?
Test plan in the early stage
- 1.Calibrate ADC channels
Using a generator to produce a well-known amplitude signal to calibrate ADC
A generator is needed
- 2.Gain VS Voltage scan (H8500: -700V <---> -1100V)
Fast Measurement: relative gain VS voltage curve
Sinle channel measurement is enough
Setup: LED->fiber->Any single pixel->Readout
Or no fiber: LED->Any single pixel->Readout
Longer plan measurement: absolute gain calibration
- 3.Uniformity measurement at low gain case
No fiber is needed in this test, open cathode
Challenge: A uniform distributed light should be produced -> need to figure out,Yi has experience on this
Setup: Uniform light->open cathode->64 channels readout->uniformity
- 4.Cross talk measurement
Size of a Pixel: 5.8mm X 5.8mm
Setup: LED->fiber->pixel->readout(surrounded pixels)
As suggested by Yi, do a position dependent cross-talk study---> scan fiber within a pixel to see the cross-talk effect

- bought by Xiaochao, The serial numbers are from Ramesh's record.
- 3x PS706 SN: 24509,24510, 24511.
- 1x PS755 SN: 24508
- 4x PS757 4 out of 9, 24472, 24473, 24506, 24507, 24455, 24456, 25618, 25807, 25808, record mixed UVa with JLab properties
- 2 scalers, either SIS3820 or 3821. I don't have the SN#
- according to Albert
1. PS706 SN: 24510- we use L HRS.
2. PS706 SN: 24511- we use L HRS
3. PS755 SN: 24508- we use L HRS
4. PS757 SN: 25807- in cabinet.
About rest, I don't see in my list.
