abstract = {We present the design and initial prototype results of a proton  beam profile monitor for the COMET experiment at J-PARC.  The goal of COMET is to look for charged lepton flavor  violation by direct μ to e conversion at a sensitivity of 10−19.  The 8 GeV proton beam pulsed at 100 ns with 1010 protons/s will  be used to create muons through pion production and decay.  In the final experiment, the proton flux will be raised to 1014  protons/s to increase the sensitivity.  These requirements of harsh radiation tolerance and fast readout make  diamond a good choice for constructing a beam profile monitor in COMET. We present first results of the characterization of single crystal diamond  (scCVD) sourced from a new company 2A SYSTEMS Singapore.  Our measurements indicate excellent charge collection and high carrier mobility down to cryogenic temperatures.}
