VPN Based Data Acquisition System for KASKA Prototype Detector

KASKA is a Japanese neutrino oscillation experiment to measure the neutrino mixing angle thetas₁₃ by using reactor neutrinos. This collaboration had conducted studies for the actual experiment till recently, march of 2007. As one of the studies, a prototype detector had been constructed and that is used for various studies. As almost of the prototype studies have been finished, we decided to do a trial to detect actual neutrino events at the experimental fast reactor JOYO by using the prototype detector. To detect a neutrino event from a fast reactor is experimental attempt. This paper describes briefly a present status of the experiment in focusing to the outline of DAQ, monitoring system and controlling system used there.
