VPN Based Data Acquisition System for KASKA Prototype Detector

KASKA is a Japanese neutrino oscillation experiment to measure the neutrino mixing angle thetas

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.
