Beam diagnosis high-precision linear transmission device

Abstract

The invention discloses a beam diagnosis high-precision linear transmission device which comprises a probe, a transmission rod, a bellows, a dynamic seal, an electric cylinder and a grating ruler. Thetransmission rod and the probe are connected through a screw. The transmission rod passes through the bellows, a dynamic seal. The bellows and the dynamic seal are connected through a CF ultra-high vacuum flange. The transmission rod and the dynamic seal are sealed through an O-shaped seal ring. The reading head of the grating ruler is connected with the slider of the electric cylinder. The electric cylinder is connected with the tail end of the transmission rod. The transmission rod is driven by the electric cylinder to carry out reciprocating linear motion along a guide sleeve. According tothe invention, different types of detection targets can be arranged on the front end of the transmission rod, and the measurement range can be adjusted according to use needs; the probe on the frontend of the transmission rod can measure the beam current intensity and position information to provide beam reference information for beam debugging personnel; stable and efficient operation of an accelerator is realized; and the device has the advantages of high repeated positioning accuracy and simple measurement.
