Claim 3:
4. A charged particle emission control method comprising steps of:
receiving a first detection signal obtained by detecting a current value of charged particles orbiting in a synchrotron;
performing calculation including at least time differentiation on the first detection signal to output a beam-intensity equivalent-value;
outputting a control signal for emitting a charged particle beam from the synchrotron to a beam transport system in such a manner that the beam-intensity equivalent-value matches a target value;
receiving a second detection signal obtained by detecting an intensity of the charged particle beam emitted to the beam transport system; and
switching whether the beam-intensity equivalent-value or the second detection signal is inputted to the emission controller,
wherein, when the second detection signal is received, outputting the control signal for emitting the charged particle beam from the synchrotron to the beam transport system in such a manner that the second detection signal matches the target value.
