Abstract

We present a description of the RD2 design for a silicon tracking detector and discuss its function as an integrated component of an LHC experiment. An advantage of the design is that considerable flexibility is possible in the granularity and radial position of each plane; these parameters are determined by the physics requirements as well as by the radiation environment, engineering and electronics considerations. The simulated performance of the detector is discussed and our experimental investigations of irradiation effects are summarised. The development of an analogue pipe-line and related front-end electronics for the storage and processing of the signals is described. Our work indicates the suitability of silicon as a detector for LHC experiments.

Recent results of radiation damage studies in silicon
1994, Nuclear Inst. and Methods in Physics Research, A
The RD2 Collaboration is making preliminary studies on a silicon tracking detector for use at the LHC. It is a priority that this detector should withstand the high level of radiation to be expected for LHC operation. Therefore systematic studies on the change of the detector performance due to radiation damage have been made, or are in progress. Well established results on neutron related damage at room temperature have been extended to lower temperatures, as foreseen for operation at LHC. For comparison proton damage studies have also been started. The detector properties under investigation include the reverse current, the depletion voltage and the charge collection efficiency. With a compressed 10 year LHC operational scenario we have successfully checked the ability of silicon detectors to survive the period influences of high fluence irradiation and subsequent annealing.
Study of neutron irradiated silicon counters with a fast amplifier
1993, Nuclear Inst. and Methods in Physics Research, A
Silicon detectors have been irradiated with fluences of up to 2.7 × 10¹³ neutrons/cm², and have been subsequently studied using low-noise preamplifiers with a peaking time of about 15 ns. The detector response to minimum ionizing particles was found to be close to that of non-irradiated detectors. The short integration time of the preamplifier makes the shot noise due to the detector dark current tolerable up to at least 15 μA/channel.
