DeeMe experiment – An experimental search for a mu-e conversion reaction at J-PARC MLF

A new experiment searching for a mu-e conversion in nuclear field is going to be conducted at J-PARC Material Life Science Facility. Expected single event sensitivity of the experiment is 2×10−14 with 1MW accelerator operation and 2×107s data taking. Electron spectrometer is planned to be composed of low mass thin gap multi wire proportional chambers and research and development works with the prototype detector is performed.
