A eihcon strip detector (SSD) ryrtem for use in very high rate experimentr haa been operated in Experiment E771 (Cox, 1989) at the Fermi National AcceIerator laboratory. The detector electroniu were de&red (Swoboda, 1990; Bowden, 1990; Zimmerman, to meet the rpeeific needa of Fermiiab exp 1989; Christian, 1991) eriment E771 uming ASIC chip tetr where commerc& circuits were not r&able. The eiectroniu for the SSD were deeigned to operate at rater up to 60 Mha and were operated at interaction rates up to 10' interaction/ree (beam rater of 2 x 10' proton/m). In addition to being very frut, the detector for the 1991 run w= very compact with 10000 &am& of active detector in a volamc of 5cm x 5cm x 19cm. An expaualon of the @em to 16000 channeia is planned for the next Fermilab fIxed target run. The rtrip pitch ranged Corn 26 pm in the center of the detector near the target to 100 pm pitch at the mort downstream, outer M of the detector. The readout is a iatch design with pipehned readout and appearr to have ningIe rtrip dilciencim of -75% even in the presence of a high radiation dose (-10" protoxu/d) and hi& leakage currentr(-1 r&/&rip). The detector and amociated amp&r electronicr bar presently been operated at 17' C and is designed to operate IU low aa 8' C.
