Description
In the current beseline design, the photo-coverage of the HK inner tank is 20%. For the low energy neutrino measurement (for example, a precise measurement of the solar neutrino spectrum or a measurement of the day-night asymmetry of the solar neutrino flux), higher photo-coverage is desirable. This R&D is to enlarge the effective photo-coverage using light collection system. I will show the current status of test measurements for a commercially available 30cm*30cm acrylic Fresnel lens.
