摘要: Abstract We describe details of the construction and performance a large area cylindrical cosmic ray anticoincidence detector suitable for medium energy neutrino experiment. The device provides 4π coverage with approximately 400 m2 liquid scintillator. Cosmic muons are rejected on-line an inefficiency ⋍ 10−4 which is improved to level 3 × 10−6 or less application off-line cuts. also discuss custom electronics used operate read out device. Results from studies attenuation neutral backgrounds by passive shielding included.
