  1. Update on Active RADMON sensors Federico Ravotti (TS-LEA-CMS) Maurice Glaser & Michael Moll (PH-TA1-SD)

  2. Active Radiation Monitors • + new devices (D2) 0.4 mm oxide thickness; • Isochronal Characterization of all FET types •  under way! RadFETs • Investigation on thick devices for • high sensitivity measurements •  under way! p-i-n diodes Optically Stimulated Luminescence (OSL) • Annealing studies  under way! • Radiation Hardness problems with the Readout electronics  under investigation! RADMON Meeting 22-07-2004

  3. RadFETs RADMON Meeting 22-07-2004

  4. OSL on-line sensor OSL+B OSLs deposed on GaAsP photodiodes for CERN sensor  OSL pure OSL+ Paraffin GaAsP + OSL coupled with a NIR LED • NIR LED known Radiation Hardness problems: • Diodes InGaAsP/InP 1050 nm under investigation! • GaAsP photo-sensor  unexpected Radiation Hardness problems: • (~ 30 % signal loss after ~ 2x1013Feq) • Problem under investigation; • Research of new solutions.
