Descripción
Sumario:Diamond is a nearly ideal material for detecting ionizing radiation. Its outstanding radiation hardness, fast charge collection and low leakage current allow it to be used in high radiation environments. These characteristics make diamond sensors particularly appealing for use in the next generation of pixel detectors planned for experiments at Fermilab and the LHC. Over the last year we have worked with several groups who have developed pixel readout electronics in order to optimise sensor preparation on diamond substrate for bump-bonding. We describe the four different approaches that are being actively pursued and the results of one fully bonded sensor tested in a beam. This device shows good hit efficiency as well as clear spatial correlations to tracks measured in the reference telescope. The position resolution is that expected given the detector pitch. Preparations for the next generation of CVD diamond pixel detectors will also be described.
