Scintillator Zn. S(Ag) Li on TIMEPIX 3 • Process • Scintillator attached to Si sensor on TIMEPIX 3 • A window has to be opened in the back contact • Cluster analysis to find point of interaction • Limited efficiency? • Tests spring or summer 2016 Mittuniversitetet
Boron layer on TIMEPIX 3 • Process • Deposition on TIMEPIX 3 in Linköping (when? ) • Masking, protection of bondwires … • Cluster processing will allow extreme spatial resolution • Still limited quantum efficiency due to self absorption in the converter layer Mittuniversitetet
Li. In. Se 2 • Material presented at NSS 2015 in San Diego • Check availability • Literature study – expected performance • Possibly experiments during autumn 2016 Mittuniversitetet
New semiconductor materials • Pre-study going on with Mo. S 2 and similar 2 D materials • Investigation of semiconductor performance for stacks of these materials • Methods to add 10 B? • Some preliminary results expected before summer Mittuniversitetet
Stuffed neutron detectors • Process • • Pore etching and diode formation in Silicon Filling with Li. F or BN Bodning to TIMEPIX(3) Testing with neutron sources • Detail planning in Prague on February 10 - 11 Mittuniversitetet
