Abstract
We have designed and realized a prototype of a high energy particle microst rip detector with Josephson readout circuits. The key features of this devi ce are: minimum ionizing particle sensitivity, due to the use of semiconduc tive sensors, fast speed and radiation hardness, due to the use of supercon ductive circuitry, and current discrimination, which allows the use of seve ral types of semiconductors as detector (Si, GaAs, CVD-diamond) without los s in performances. The Josephson circuitry, made by a combination of RSFQ a nd latching logic gates, realizes an 8-bit current discriminator and parall el to serial converter and can be directly interfaced to room temperature e lectronics. This device, which is designed for application as vertex detect or for the Compass and LHC-B accelerator experiments, has been tested with small radioactive sources and will undergo to a test beam at the C.E.R.N. S PS facility with 24 GeV/c protons. Current results and future perspectives will be reported.
