Recent results on the radiation hardness of silicon detectors fabricated on gloat zone bulk silicon enriched by carbon and oxygen are reported. The results indicate that the radiation hardness of silicon detectors can be determined by the concentration of oxygen and carbon atoms in the bulk material. The study has been carried out in the framework of the RD48 collaboration, which is studying the radiation hardening of silicon detectors.
Preliminary results from Gamma ray experiment installed on a micro-satellite, Techsat 1, are reported. The experiment is based on CdZnTe detectors coupled to custom designed CMOS electronics, which includes low noise charge sensitive preamplifiers, pulse shaping amplifiers and sampling circuits. It was realized as a mile stone towards a micro- satellite mounted Gamma ray space telescope. The experiment is a stand-alone spectroscopy system that measures the radiation inside the micro-satellite and transmits the spectra to ground station via the main satellite computer. The radiation level inside micro-satellites is expected to be significantly lower compared to that inside large satellites. Additional goal of the experiment is to test the CdZnTe detectors and the front-end electronics, implemented in a standard CMOS process, under space radiation environment. In particular, the degradation in performance will be monitored. The Techsat 1 micro-satellite has been designed and constructed at Technion-Israel Institute of Technology. The satellite is approximately 50 X 50 X 50 cm-3 cube with a total weight of about 50 kilograms. It was successfully launched in July 1998 to a 820 km orbit.

An x-ray detector experiment is presented. The experimental setup integrates on board new and commercially available x-ray detectors, custom designed charge sensitive amplifiers, signal processing, control unit and memory chips. The experimental system is included in TECHSAT (Technion Satellite), scheduled to be launched in 1994.
