| Research Abstract |
A calibration system that inserts gamma or X-ray sources into a dark matter search detector and calibrates mainly position where scintillation photons were generated inside the detector was produced. Position and energy resolutions and trigger efficiency were measured, and optical parameters of materials inside the detector were calculated using a Monte Carlo simulation. Based on the result dark matter search experiment was conducted and certain parameter region which is allowed by other experiments for light mass WIMP around 10 GeV was excluded.
