Seminare de DPNC ================ Mercredi, 28. mai 1997 17.00 - Auditoire Stuckelberg Universite de Geneve Departement de physique nucleaire et corpusculaire 24, quai Ernest-Ansermet 1211 Geneva 4 Tel. 022 702 6273 Fax. 022 781 2192 ****************************************************************************** Sujet: Silicon microstrip detectors for high energy physics experiments: a review Par: Dr. Davide Vite DPNC/ Universite de Geneve Resume: Since a few decades silicon detectors have been made use of in particle physics experiments, with systems of a complexity never imagined before now under construction or design, such as the tracker system for the AMS experiment or the silicon central detectors for the approved LHC experiments. A review of microstrip detectors will be presented starting from the basic principles and functioning, summarising topical properties such as possible single and double-sided geometries, and bulk and surface characteristics such as interstrip isolation, resistance, capacitance. Material budget concerns are not minor in sensitive experimental configurations. The microstrip systems used at LEP collider experiments will be briefly presented, among other. Recent developments for LHC detectors, where the radiation hardness is a major issue, will be discussed, along with the proposed configurations and geometries. Vaste programmes of radiation hardness studies and test irradations have been and are being carried out since a few years to this purpose, with important results and consequences to microstrip manufacturing.
