We present a new model which represents the mechanism of loss of ions stored in a radio frequency quadrupole trap. We observed the storage time and the temperature of Mg⁺ ions as a function of the cooling gas (He) pressure in the presence of Kr gas, which is introduced as a heavy collision partner. Our model well reproduces the observation.
