  1. Sensor ReviewSlides for Jörn Talk IBL Sensor Review Kick-off Meeting CERN, May, 4th 2011 G. Darbo / INFN-Genova Indico agenda: https://indico.cern.ch/conferenceDisplay.py?confId=135725

  2. prototype program & tests

  3. FE-I4 Assemblies • Already made assemblies • CiS: 35 of which 10 of IBL design • CNM: 8 of which 8 of IBL design • FBK: 8 of which 0 of IBL design • Assemblies to be made with priority with IBL design • CiS: 10 • CMN: 7 • FBK: 12 + 4 (to x-check prior assembly test with removable metal)

  4. FE-I4 Performance • Analog performance of FE-I4 are better than for FE-I3 • Noise ~130÷150e- with sensors before irradiation, chip simulation gives a noise of 220e at 50nA leakage current and 400fF capacitance. No systematic studies done yet with irradiated sensor, but first measure confirm it. • 3 FE-I4 irradiated (Los Alamos 800 MeV protons) at 200 Mrad: threshold dispersiondoesnot change, while noise increasesbyabout 20%, nosystematiceffects. • No systematic studies of minimum operating threshold: unirradiated assemblies successfully tuned at 1500e- (and below).

  5. FE-I4 Wafers • Total of 16 FE-I4 wafer available for IBL prototypes • 9 fully probed and analyzed • 65% average yield • Additional 6 wafer bought from spare IBM production for IBL uses. Not delivered yet.

  6. Irradiated Devices • Irradiate devices with p (Karlsruhe - KS) of 23MeV and neutrons (Ljubljana - LJ) from reactor. Qualification dose: 5E15N or 5E15P neq/cm2 • Karlsruhe: DUT on SCC → test → irradiate → test → test beam • Ljubljana: DUT on SCC → test → remove DUT from SSC → irradiate → reload on SCC → test → test beam • Plan to have for CERN test beam in May/June • CiS: 4 KS + 4 LJ - CNM: 2KS + 2LJ - FBK: 2KS + 2LJ • More devices will be irradiate to recover handling failure (especially for LJ)

  7. Test Beams with FE-I4 • Desy: • February From, Alessandro, Jens & Philippe Slides No results, only what has been done

  8. May/June Test Beam at CERN Problem with TAX in the north area, all FT affected. At least 5 weeks delay! Risk to loose beam period! • IBL test beam: May 20 to June 13 • Morpurgo Magnet • Ciller box with temperature control IBL Reference for Schedule: http://sps-schedule.web.cern.ch/sps-schedule/

  9. Cold Box for Test Beam • Special cold box in preparation for CERN test beam in May/June • Up two 6 modules, design specs: • Sensor temperature: -20ºC • Heat load: 5 W / module • Adjustment w.r.t beam line of pitch and jaw angles • Active liquid cooling of individual modules: graphite cold plate in contact with the DUT (low X0) • Commercial recirculating chiller 120 W @ -40ºC (LAUDA RK20-KS) • Specs: http://www.lauda.de/hosting/lauda/website_en.nsf/urlnames/KPEI-5D2MQR/$file/Yace050a.pdf
