Title:
CHARGED PARTICLE BEAM DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/090129
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a charged particle beam device capable of continuous stable operation with low noise and high efficiency. In the charged particle beam device, a high-voltage power source (103) and a charged particle gun (114) containing a charged particle source are connected through a high-voltage cable (106). The charged particle beam device comprises: a power-receiving coil of a power-send-receive device (124) installed in a hollow portion of the high-voltage cable (106) and supplying the power used in the charged particle gun (114); and a power-sending coil of the power-send-receive device (124) installed on the outer side of the high-voltage cable (106) and sending power. The power is transmitted by magnetic field resonance coupling between the power-sending coil and the power-receiving coil.
