Abstract：
The water tank prototype with a dimension of 1m×1m×13m was constructed as a building block of the Cerenkov calorimeter for very long baseline neutrino oscillation experiments. The effective attenuation length of the water tank was measured to be (5.74±0.29)m, and the light collection probability as a function of the incident angle of the particle is studied. Results are compared with a Monte Carlo simulation based on GEANT4 package which incorporates detailed optical processes. A good agreement is achieved and the water tank is feasible for the construction of the Cerenkov calorimeter.
