EP-DT-DD Intro Detector Development • Two main project: • SSD Team § RD 50 collaboration • Skiroc team § CMS HGCal project • SSD Team (RD 50) § § Lead by Michael Moll(deputy group leader of EP-DT) Labview software development Mechanical prototyping and cooling system development New main (independent) software for several instrument in the lab (Keithley 2410, Keithley 2000, TTi TSX 3510 P, Laird PR 59, Agilent scope, and so on) • Main project: TCT master software (One SW to rule them all) § Labview software for TCT (transient Current Technique) measurements that can run on several work places within the SSD lab § Stability and speed improvements • Side software tasks § § Full VI revision and update Interfaces normalization IO clustering for main Vis Parallelization of all main software and working loops. • Skiroc Team (CMS HGCal) • § Lead by Dave Barney (manager of HGCal project for CMS) § New main (independent) software for several instrument in the lab (Tektronic and Lecroy scopes, Agilent E 3630 A and TTi TG 5011) Main Project: Skiroc 2 test bench design and development § All hardware has been selected, purchased or rented and installed § First workbench with Skiroc 2 board, already working. § Second workbench for Skiroc 2 CMS is on going. Some tips needed from Omega (developers) but measuring already working § Very complex and advanced DAC systems with several iterations, involved institutes from France and USA § There is a little team on my back, to do the work with me. All of us sharing time from other projects SSD - Solid State Detector Lab - Nov 16 -3 -

EP-DT-DD Detector Development Skiroc subproject (High granularity calorimeter for CMS end caps) SSD - Solid State Detector Lab - Nov 16 -4 -

EP-DT-DD Detector Development The needs • CMS and Atlas are rushing to their Hi. Lumi upgrade • Actual end cap electronic and hadron calorimeters will not survive the radiation increase • Improving the calorimeter and its radiation hardness means a change in the sensors AND • • in the DAQ Front & Backend systems Many sensors implies many channels so… We need a new way: new design of readout chips and smarter electronics embedded in the detector, 600 m 2 of silicon detectors will be implemented and need a new readout chip: Skiroc 2 CMS SSD - Solid State Detector Lab - Nov 16 -5 -

EP-DT-DD Detector Development • • • The solution Skiroc 2 CMS is an evolution from the Skiroc chip family. My main task in this project is to stablish a Skiroc knowledge base at CERN Keeping in touch with developers: Stéphane Callier and Christophe de la Taille (CNRS-Omega) I set up a workbench lab from scratch, and we are testing the different parts of the device in term like SNR, systematic noise, offset and any other issue we can have during the operation (HL-LCH run 1) We started with skiroc 2 development board, and I developed the tools which will be used to repeat the same study when Skiroc 2 CMS arrives. Automatization of massive number of ROC channels. SSD - Solid State Detector Lab - Nov 16 -6 -

EP-DT-DD Detector Development skiroc 2 • Skiroc 2 assets (towards Skiroc 2 CMS): § 64 Channels. Fully independent § Preamplifier (adjustable gain) § High dynamic range (two parallel amplifiers) • 0. 5 to 150 MIPs (High Gain amp) • 150 to 2500 MIPs (Low Gain amp) §Auto trigger + Analog + Digitalization (On chip) §Token ring read out All 64 channels has its own parameter for trigger and Delay, both amplifiers and dedicated SCA memory • Work status § Test lab fully deployed § First measurements on going § Measurement automatization ongoing • Next steps § Mass measurements to generate statistics § Data analysis of “massive” in-lab data Control software developed by Omega SSD - Solid State Detector Lab - Nov 16 -7 -

EP-DT-DD Detector Development skiroc 2 CMS • Software suite § Very different software, to manage all the devices § Some proprietary software (Xilinx Vivado), some freeware (like SSH, SFTP or serial command interface) and some self designed software to automatize several tasks § No integration at all § Parser needed to simplify data readout. Probably, C++ (Qt toolkit) or Labview SSD - Solid State Detector Lab - Nov 16 -8 -

EP-DT-DD Detector Development SSD Software development and engineering support (RD 50 - Radiation hard semiconductor devices for very high luminosity colliders) SSD - Solid State Detector Lab - Nov 16 -9 -

EP-DT-DD The needs Detector Development • Solid state devices are based in the PN junction concept. High exposition to radiation change the device properties • Actual technologies cannot cope with Hi. Lumi requirements. Fluences of 1 e 16 neq/cm 2 is too much for any semiconductor based technology we have… up to now • Solid State Community’s efforts are in a variety of new devices: LGADs, Pi. N Diodes, Monolithic technologies, APDs, DEPFETs… to increase radiation hardness. ! t!!

EP-DT-DD Detector Development The solution • We need a better understanding of solid state detector in high intensity radiation fields • RD 50 collaboration is formed by 50 institutes, more than 300 members, 22 observers universities • and laboratories. New techniques and models are developed to study radiation hardening of solid state detectors. Now, we are able to measure the electric field in the detector bulk.
