Status of the laser test setup and test beam news Dmytro Hohov

TB plans (period : 4th – 25th July, at CERN) LAL period 8-15 July (with MPI group) LPNHE: 6-11 July MPP samples for July 2017 RD53A modules built with SOI4 sensors with different topologies 50x50 25x100 100 um thick 150 um thick No PT With PT *Still to be delivered from IZM SCC cards still missing + some of them have to be reworked to remove the copper plate for irradiation

Tooling and an interlock system for the laser operating

Instrumentation Laser light power meter PC with linux: standalone C++ program, that reads histograms from a TOT_CALIB scan and use them to convert ToT from raw data SOURCE_SCAN to charge. So we can get the collected charge, knowing the injected charge the CCE can be calculated Temperature and humidity meter The rack with laser system devices

Laser system setup Analysis is an important step in the development New optics (larger working distance) Space for the cooling Space for the rotation New production with openings*

Col 0 Wire bonding side Col 80 1000 125 1000 What we want to have: Left edge side (col 0)– is half covered with Al; Right side is fully covered with Al to compare efficiency at test beam Holes 30 by 80 as was in previous design (the pixels should be well efficient ) Large openings ( 1mm by 1 mm). Maybe we can have a few different sizes (500 um by 500 um or the like), pixels perhaps will be less efficient with the large opening, but less reflection, and full pixel area to test.
