Description

TECHNICAL FIELD

[0001] The present application relates to the injection line related technical field, especially to a portable angle adjusting mechanism for cyclotron injection line. BACKGROUND

[0002] There is an angle installation requirement between the accelerator deflection plate and the injection line magnetic pole, and a hard connection is currently adopted, and then the beam direction is fine-tuned through electric control to exclude the machining error of the device itself. Since the accelerator deflection plate is a single-arm support structure due to space limitation, there is an installation error. The injection line is also casted as a whole, and the magnetic pole concentricity position degree requirement cannot be generally accurate in theory calculation. Therefore, it is often found that even if the electric control is set to the limit value, it is still far away from the expected result. During the debugging period, a certain improvement is obtained by rotating the fixed angle, but because of the limitation of the fastening hole, the rotation angle can only be the fixed multiple value of 360 / n (the number of screw holes), which is not convenient for adjustment. For a production enterprise, how to improve the efficiency is the most important. In view of this problem, a portable angle adjusting mechanism for cyclotron injection line is needed to be designed.
