Calibration of liquid argon detector with ${}^{83m}Kr$ and ${}^{22}Na$ in different drift field

Weixing Xiong, Mengyun Guan, Changgen Yang +7

${}^{83m}Kr$ and ${}^{22}Na$ have been used in calibrating a liquid argon (LAr) detector.${}^{83m}Kr$ atoms are produced through the decay of ${}^{83}Rb$ and introduced into the LAr detect…
