We discuss the results obtained from the R&D; studies, done within the CMS experiment at LHC related to the behaviour of silicon microstrip prototype detectors when they are operated at high bias voltages before and after heavy irradiation, simulating up to 10 years of LHC running conditions. We have found detectors from several manufacturesrs that are able to work at V_bias > 500 Volts before and after the irradiation procedure, maintaining an acceptable performance with S/N > 14, efficiency close to 100% and few ghost hits..

The paper describes the Silicon Tracking System of the Compact Muon Solenoid ( CMS) and reviews the most recent results of the R&D; activity on radiation resistant microstrip silicon detectors. The Silicon Tracker of CMS consists of 5 layers of microstrip detectors in the barrel and 10 disks on either side of the end-cap region. [...]

CMS silicon tracker developments
/ Civinini, C ; Albergo, S ; Angarano, M M (INFN Perugia and Univ., Bari, Italy) ; Azzi, P ; Babucci, E ; Bacchetta, N ; Bader, A ; Bagliesi, G ; Basti, A ; Biggeri, U et al.
The CMS Silicon tracker consists of 70 m/sup 2/ of microstrip sensors which design will be finalized at the end of 1999 on the basis of systematic studies of device characteristics as function of the most important parameters. A fundamental constraint comes from the fact that the detector has to be operated in a very hostile radiation environment with full efficiency. [...]

/ Demaria, N ; Albergo, S ; Angarano, M M ; Azzi, P ; Babucci, E ; Bacchetta, N ; Bader, A J ; Bagliesi, G ; Basti, A ; Biggeri, U et al.
Interstrip and backplane capacitances on silicon microstrip detectors with pf strip on n substrate of 320 mu m thickness were measured for pitches between 60 and 240 mu m and width over pitch ratios between 0.13 and 0.5. Parametrisations of capacitance w.r.t. [...]

High-voltage breakdown studies on Si microstrip detectors
/ Albergo, S ; Angarano, M M ; Azzi, P ; Babucci, E ; Bacchetta, N ; Bader, A J ; Bagliesi, G ; Basti, A ; Biggeri, U ; Bilei, G M et al.
The breakdown performance of CMS barrel module prototype detectors and test devices with single and multi-guard structures were studied before and after neutron irradiation up to 2-10/sup 14/ 1 MeV equivalent neutrons. Before irradiation avalanche breakdown occurred at the guard ring implant edges. [...]
