2. The Experimental HEP group at ICCUB The Experimental HEP group at ICCUB has a long record of electronic development, based on a strong collaboration with Electronic department & others: –For particle physics experiments: Calorimetry, Tracking This has produced a strong expertise on: –ASIC design (new chips) –Control systems –Data Acquisition systems –With harsh conditions: radiation, cooling, power, frequency, etc. Key points: –No constant working level ( peaks at detector construction, upgrades, test …) –Budget fluctuations (actually decreasing) –Experienced engineers and technicians based mainly on temporary contracts We want to keep and exploit this expertise. Solution: (I) extend fields of application: –For astroparticle experiments: Cherenkov –Future experiments: Silicon Tracker –Medical imaging: Silicon PMTs –Other applications (II) under a given structure: SiUB 20/10/20142Introduction to SiUB
