Commissioning for TB2017-06 at DESY

Slabs commissioned

We have commissioned slabs 13-22.

Information about the slabs is in https://forge.in2p3.fr/projects/calice/wiki/Si-WEcalSLABS

For example, if one looks into https://forge.in2p3.fr/projects/calice/wiki/SiWEcalSlab13 will see:

sU_4b_11_F_#13

FEV11 n33

SMBV4b n11

Then, the PCB n 33, corresponds to the row 5 of the table table, and the wafers Wafers n 10 13 15 14

There is also an ASU table (PCB+Wafer) https://forge.in2p3.fr/projects/calice/wiki/Si-WEcalASU

Bad Slabs history

Slab 13: issue when gluing the SMB at LAL, laso a short in M21 (fixed)

Slab 14: jumper s9 broken, very high leakage (~10ua for 100V at 20degrees), chips 4-7 lost during data acquisition.

Slab 15: ? Nothing was wrong with it.

Commissioning results

A comprehensive commissioning procedure has been done before the test beam. It consisted in two phases: the commissioning of single slabs and the commissioning of the full proto with 7 slabs. Slabs 13,14,15 were considered not ready for the beam test. Slab 16-22 were found optimal, and used in the beam test.

Proto passport (7 slabs)

Summary of dead channels = 0 !!

Summary of masked channels: Total # of channels not masked --> 6204 (87%)

Layer 1, Slab 21 → 43.4% (one wafer) Layer 2 6 , slabs 16,-20 ~6-8% Layer 7, slab 22, ~ 16% (one chip)

5% are masked manually just before starting the commissioning → same patter in all slabs: Chn 37 in all chips, Chn 41-53, chips 1,9 Chn 5, chips 0 and 8 Chn 3, 9, 10, chip 7 and 15

The trigger threshold were set chip-wise as the maximum of the scurve threshold + 5 sigmas or 225 DAC.
