Minutes

Hardware

FEB mezzanine boards for HV and LV are here (10 each).

Breakout board for hybrid testing next week. 

Layout work on HV flange starts today, ready mid next week (HV first). Expect to review next meeting on HV and order after that. 

RTM layout done. Get it in 2weeks time. 

Final COB board is here and looks good. We can use that for developing. Ryan are waiting to place large bulk order for our and other experiments.

FEB status

There is a voltage regulation issue on the analog side; trimming of voltages didn't work but Ben identified it as a bad component and nothing wrong with the FEB board.

Next week ready to start testing with hybrids.

Hybrid testing

Omar reported that the testing of two new bonded hybrids were all ok. We can go ahead and build a L4-6 half-module with them.

Event sizes

Omar showed older calculation of the event sizes. We decided that what we are interested in is the number of hits per sensor since the data format will change. We also want to know the expected hits depending on the layer/sensor position. The idea is that we can see how well we are balancing the events out per RCE. There are 14 RCE's in total and 36 hybrids. Idea is to process data from 2 hybrids/RCE in L1-3 and 3 hybrids/RCE in L4-6. 

Omar promised to calculate and send the hit counts per sensor.
