Title
Diamond Detectors for Particle Physics
Contributors
AS Howard
Abstract
Chemical Vapour Deposited (CVD) diamonds have been investigated for particle physics applications. A review of the requirement for a particle physics vertex detector is given, and the need for a radiation hard material discussed. Special attention is given to the measurement of CP violation in the B-meson system in the LHC-B detector at the proposed Large Hadron Collider (LHC) at CERN. An overview of the properties of diamond and their relation to characterisation techniques are presented and applied to particle detectors. Charged particle detection has been characterised with a sensitive set-up for measuring the response to minimum ionising charged particles. High energy particle beam tests have been carried out and the subsequent analyses of data are presented. Extensive neutron irradiation studies have been undertaken, with the first evidence for damage seen in CVD diamond particle detectors. A model has been developed which explains the observed degradation in particle detection as a result of neutron damage. In order to utilise diamond detectors in a high radiation, high particle density environment, a novel pixel read-out amplifier chip has been studied and tested. Initial tests of this amplifier were performed using silicon as the detecting material, including chip functionality, and beam tests in a 2T magnetic field. A comprehensive Monte Carlo model has been developed, and the comparison with other systems is made in the simulation. It is believed that diamond material of sufficient quality to operate in the LHC will be produced within its lifetime, although the problem of radiation hardness is not definitively solved.
