Description
A prototype of a novel detector using single-crystal chemical vapor deposited
diamond and resistive electrodes in the bulk forming a 3D diamond device
will be presented. The electrodes of the device were fabricated with laser
assisted phase change of diamond into a combination of diamond-like-carbon,
amorphous carbon and graphite. The connections to the electrodes of the 3D
device were made using a photo-lithographic process. A prototype detector
system consisting of the 3D device connected to a multi-channel readout was
successfully tested in a 120GeV proton beam at CERN proving for the first
time the feasibility of the 3D diamond detector concept for particle tracking
applications. The electrical properties and beam test results of the
prototype device will be presented.
