Voltage Division Resistor for Acceleration Tubes, Acceleration Tube, and Accelerator

摘要

To provide a voltage division resistor for acceleration tube, an acceleration tube, and an accelerator capable of reducing the cost of the acceleration tube and enhancing the operation efficiency. [MEANS FOR SOLVING PROBLEMS] An acceleration tube (1) for accelerating ions (charged particles) I by applying an acceleration voltage V comprises a tubular acceleration tube body (2) made of synthetic resin, a plurality of ring-like acceleration electrodes (3) arranged in a row on the inner circumferential surface (2a) of the acceleration tube body (2) at predetermined intervals in the axial direction of the acceleration tube body (2), a plurality of voltage division resistors (voltage division resistors for the acceleration tube) (5) wound spirally on the outer circumferential surface (2b) of the acceleration tube body (2), and a plurality of terminal bolts (terminal member) (4) provided in close contact with the acceleration tube body (2) while penetrating the acceleration tube body (2) radially and having a forward end (front end) (4a) connected electrically with the acceleration electrodes (3) and a head (rear end) (4b) connected electrically with each connector (connection point) (16) of the voltage division resistor (5).
