The method of the dee voltage measurement using the turn separation of beam and the device for turn separation measurement

摘要

PURPOSE: A method of measuring a dee voltage of a cyclotron and a probe for measuring the dee voltage are provided to easily and effectively measure the dee voltage. CONSTITUTION: A probe (40) measures a dee voltage of a cyclotron and includes a body (42) and a beam passing part (45). The body is a member in a plate rod shape and is arranged lengthways in the direction perpendicular to the acceleration direction of a spirally-accelerated beam. The beam passing part is formed on the body in a slot shape. The beam passing part sends a part of the beam accelerated in the cyclotron and scatters a part of the rest by colliding with the body.
