BEAM POSITION MONITOR DEVICE AND PARTICLE RAY TREATMENT DEVICE

Title:

BEAM POSITION MONITOR DEVICE AND PARTICLE RAY TREATMENT DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/108393

Kind Code:

A1

Abstract:

The purpose of the present invention is to reduce the interval for acquiring the position of irradiation by a charged particle beam, even in the presence of an effect of radiation generated during irradiation by the charged particle beam. A beam position monitor device (30) is provided with a plurality of position monitors (4) and a beam data processing device (11) for computationally processing the state of the charged particle beam (1) on the basis of a plurality of signals outputted by the position monitors (4). The beam data processing device (11) has: a plurality of channel data converter parts (21) for executing AD converter processing on the plurality of signals outputted by the position monitors (4); position size processors (23) for calculating the beam position of the beam (1) on the basis of the voltage information which has been subjected to AD converter processing, a position size processor (23) being provided for each position monitor (4); and an overall controller (40) for controlling the plurality of channel data converter parts (21) so as to execute AD converter processing on the plurality of signals in a staggered manner for each corresponding position monitor (4) while the beam (1) is being beamed onto the irradiation subject (15).
