<P>PROBLEM TO BE SOLVED: To provide a system and a method for charged particle irradiation which is capable of shortening the irradiation time and shortening the treatment time by performing efficient irradiation even when irregular variation occurs in an object to be irradiated during gate irradiation. <P>SOLUTION: Beam emission is stopped by regular emission permission end signal reception by regular movement signals. In the meantime, an emission possible state maintaining function 46b is activated by emission permission end signal reception. When set standby time elapses without receiving an emission permission start signal again during standby, the operation of the emission possible state maintaining function 46b ends. A charged particle beam generator 1 decelerates the beam. Sometimes the beam emission is stopped by irregular emission permission end signal reception during irradiation. In the meantime, the emission possible state maintaining function 46b is activated by the emission permission end signal reception, and the charged particle beam generator 1 maintains an emission possible state. When the emission permission start signal is received again during standby, the beam emission is restarted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
