Description
Detectors based on Chemical Vapor Deposition (CVD) diamond have been used successfully in beam conditions monitors 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 after fluences of 10^{16}/cm^2 and 10^{17}/cm^2. Diamond is one candidate due to its large displacement energy which enhances its radiation tolerance.
Over the last few years the RD42 collaboration has constructed and characterized detectors using CVD diamond material with a planar geometry and more recently with a 3D geometry to extend the materials' radiation tolerance. In this talk, we present test beam results of the latest planar and 3D diamond pixel detectors measured in the MALTA telescope at CERN using our prototype diamond detector ASIC. The 3D cells in these detectors have a size of 50µm x 50µm with columns 2.6µm in diameter and 100µm x 150µm with columns 4.0µm in diameter. A description of the production techniques used to produce these devices and beam test results for detectors will be presented and compared.
