After phenomenologically considering the RF heating the RF heating as an additive contestant to the buffer gas damping, we calculated the storage time of trapped ions in terms of the mean first passage time of the Brownian motion of their energy in the pseudopotential well of a Paul trap.

RFID is one of the automatic equipment identification,which develops rapidly recently.
