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 that enhances
its radiation tolerance. Over the last 2 years the RD42 collaboration has
constructed 3D CVD diamond detectors that use laser fabricated columns to
enhance radiation tolerance. The cells in these detectors had a size of
50µm x 50µm with columns 2.6µm in diameter. The beam test results for
both un-irrdiated and irradiated detectors will be presented.
