Comet machine for the detection of the impuritie while the process of the diamond is being performed

SLTL has designed this COMET machine for the detection of the impurities while the process of the diamond is being performed. It scans the diamond and changes its colors to know the impurities zooming it up to 200X. We present the design and initial prototype results of a proton beam profile monitor for the COMET experiment at J-PARC.
