Abstract content

E61 is a proposed water Cherenkov near detector in the J-PARC neutrino beam. We will describe the design of the E61 detector; in particular, we will focus on the photosensors and electronics for E61. Key challenges for the design include maintaining good reconstruction performance for a relatively small inner volume and handling large rate of pile-up events from the high-intensity J-PARC neutrino beam. Our design is based on the 'mPMT' module; using sets of twenty four 3" PMTs assembled in acrylic and metal cylinders, mounted on a support frame. Over the past year we have made substantial progress on the design and construction of an mPMT prototype for E61, including: detailed characterization of the candidate 3" PMTs; tests of various optical gels; prototyping of the 3-D printed support structure for holding the PMTs; design of the low-power waveform digitizing electronics. We will also show updated estimates of the reconstruction performance for the E61 mPMT design.
