Description
Results from prototypes of a novel detector using 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 detector system
consisting of 3D devices, one based on single-crystal CVD diamond and one
based on poly-crystalline CVD diamond was connected to a multi-channel
readout and 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 devices will be presented.
