Abstract: RD39 collaboration develops new detector techniques for particle trackers, which have to withstand fluences up to <f>1016 cm−2</f> of high-energy particles. The work focuses on the optimization of silicon detectors and their readout electronics while keeping the temperature as a free parameter. Our results so far suggest that the best operating temperature is around <f>130 K</f>. We shall also describe in this paper how the current-injected mode of operation reduces the polarization of the bulk silicon at low temperatures, and how the engineering and materials problems related with vacuum and low temperature can be solved.
