Development and test of TAB bonded silicon PAD detectors and micro-cables for the construction of silicon probes for imaging

Detection and spectroscopy tests of the first functional unit of a self-dependent silicon detection module constructed on the base of micro-cable and TAB technology are presented. The tests were performed using pulse-height analysis of the signals induced by gamma rays in the silicon sensor. Good shapes of the spectra and satisfactory spectroscopy resolution (given by FWHM which is less than 2 keV) correspond with results on wire bonded modules. This fact demonstrates that the micro-cable technology does not degrade performance of the detection modules and the TAB is a prospective technology for construction of small stack of self-triggered spectroscopy system suitable for medical applications where very dense packaging of sensors and front-end electronics into small volumes is necessary.
