| Research Abstract |
The CHORUS experiment stored one million neutrino interactions in nuclear emulsion target. While the past analysis for neutrino oscillation and charm analysis such for short life time particle detection was just based only 0.2 million events. The limitation of the analyzed event comes from limitation of scanning power and inefficiency due to target tracker prediction accuracy tail.
Then the aim of this study is locating of 1 million neutrino events by faster scanning machine and deal about 20,000 charmed particle associated events.
The R&D of improving track finding efficiency and reducing background tracks in the large area scanning like level of 10cmx10cm was done.
And the parameters of track goodness are tuned to keep signal background level and track finding efficiency and the track pick up for event location was done.
All neutrino event location in the CHORUS detector and neutrino events with charmed particle will be followed.
