 ARRAY: An Open Source, Modular and Probe-Card based System with Integrated Switching Matrix for Characterisation of Large Area Silicon Pad Sensors / Pitters, Florian Michael (Austrian Academy of Sciences (AT)) ; Brondolin, Erica (CERN) ; Dannheim, Dominik (CERN) ; Kulis, Szymon (CERN) ; Maier, Andreas Alexander (CERN) ; Quast, Thorben (Rheinisch Westfaelische Tech. Hoch. (DE)) ; Sicking, Eva (CERN) Silicon pad sensors are proposed as active material in highly granular sampling calorimeters of future collider experiments such as the Compact Linear Collider (CLIC) or the International Linear Collider (ILC). The electromagnetic section of these designs often include O(1000m2) of silicon pad sensors. [...] CLICdp-Pub-2019-002.- Geneva : CERN, 2019 - 12. Fulltext: PDF;
