Progress in diamond detectors

Conference item

Detectors based on Chemical Vapor Deposition (CVD) diamond have been used successfully in Luminosity and Beam Condition Monitors (BCM) in the highest radiation areas of the LHC. Future experiments at CERN will accumulate an order of magnitude larger fluence. As a result, an enormous effort is underway to identify detector materials that can operate under fluences of 1 · 1016 n cm−2 and 1 · 1017 n cm−2. Diamond is one candidate due to its large displacement energy that enhances its radiation tolerance. Over the last 30 years the RD42 collaboration has constructed diamond detectors in CVD diamond with a planar geometry and with a 3D geometry to extend the material’s radiation tolerance. The 3D cells in these detectors have a size of 50 μm×50 μm with columns of 2.6 μm in diameter and 100 μm×150 μm with columns of 4.6 μm in diameter. Here we present the latest beam test results from planar and 3D diamond pixel detectors.
