Development of novel Silicon detectors for next generation nuclear physics experiments (SIDET) O. Kiselev University of Mainz JRA21/JRA22
Integrated E – E detectors New technological process – Quasi-Selective Epitaxy E-E scatter plots obtained after irradiation by heavy ions and alpha particles Novel double-sided monolithic E-E detector Potential applications – GANIL, LNL Legnaro, LNS Catania, GSI
Membrane-like E detectors Anodic dissolution of large area n – n+ epitaxial oxidated structures Potential applications – GANIL, LNL Legnaro, LNS Catania, GSI Very thin strip detectors produced by new technology - Planar Process Partially Performed on Thin Silicon Membrane (PPPP process) Passivated 52 µm thick transmission E strip detector
Sub-segmented strip detectors 2D position sensitivity on one side (like pixel detectors) Same number and type of readout channels as strip detectors 30 - 50 µm position resolution is possible Large pads on back side for timing/trigger Thin dead layer on front side – low energy threshold Spectroscopy Potential applications – any nuclear physics experiment, medicine, safety Absolutely novel technique!
Thick Si calorimeters Very good energy resolution High efficiency Low noise Thick (7-10 mm) Li drifted Si detectors (SiLi) Very expensive Very long and complicated production process Almost no producers in the world Thick (≥3 mm) Si PIN detectors Very good energy resolution High efficiency Low noise Simple and fast production Any active area possible Low price Need an R&D on voltage termination at the detector periphery Careful choice of the Si wafers Potential applications – GANIL, LNL Legnaro, LNS Catania, GSI
Particle and ion ID Spectroscopy Position measurement Self-triggering, TOF measurement Integrated E-E detector Summary of JRA activity Membrane-like strip detector Sub-segmented strip detector Thick Si calorimeters Merging potential with some other JRAs – dialog is going on Substantial improvement Full advanced telescope for charged particle detection
