Description
We have measured the pulse height and spatial resolution in 3D detectors
constructed with single-crystal and poly-crystalline CVD diamond. The work
using single-crystal diamond was performed in 2014 and published in 2015[1].
Since our first results we have constructed 3D detectors using poly-crystalline
diamond. Our results indicate that the 3D geometry allowed us for the first
time to collect essentially all the deposited charge in a poly-crystalline
diamond detector. This result indicates that the grain boundaries in
poly-crystalline material may not be fundamental impediments to
charge collection in diamond. The electrical properties and beam test
results from 2015 and 2016 of the recent single-crystal and poly-crystalline
3D devices we have constructed will be presented and compared.
