  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.
