Scintillation light increase of carbontetrafluoride gas at low temperature

Scintillation detector is widely used for the particle detection in field of physics. Particle detectors containing fluorine-19 ($^{19}\mathrm{F}$) are known to have advantages Weakly Interacting Massive Particles (WIMPs) dark matter search, especially spin-dependent interactions with WIMPs due its spin structure. In this study, scintillation properties carbontetrafluoride ($\mathrm{CF_{4}}$) gas at low temperature was evaluated because dependence light yield has not been measured. We by cooling from room (300K) 263K. As a result, $\mathrm{CF_{4}}$ found increase $(41.0\pm4.0_{\rm stat.}\pm6.6_{\rm syst.})\%$ and energy resolution also improve temperature.
