Description
We present the design and initial prototype results of a pixellized proton beam profile monitor
for the COMET experiment at J-PARC. The active element of the detector is single crystal diamond grown
by chemical vapor deposition (sc-cvd). The goal of the COMET experiment is to look for charged lepton flavor
violation by direct $\mu$ to e conversion at a sensitivity of $10^{-18}$. In the first phase, an 8 GeV proton beam
pulsed at 100 ns with current corresponding to $10^{10}$ protons/second will be be used to create muons through
pion production and decay. In the final experiment, the proton flux will be raised to $10^{14}$ protons/sec to
increase the sensitivity with an intense muon beam. These requirements of harsh radiation tolerance and fast
readout have led us into developing a sc-cvd diamond based pixel detector to profile the proton beam.
The design details and first prototype readout results of the detector will be presented.
