MOPP052 | Development of 5-Cell β=0.9 650 MHz Elliptical Cavities for Project X | 171 |
|
||
Several 5-cell 650 MHz elliptical cavities have been fabricated for the PIP-II Project. Two versions of the cavities have been designed to accelerate protons of relative group velocity of β=0.9 and β=0.92 in the high energy region of the linac. In this paper, we report the development status of these cavities, summarize the results of the quality control measurements performed on five initial prototypes, and outline the VTS test results. | ||

Test of Electromechanical Actuators for SRF Cavity Tuners | |
|
||
SRF cavities required slow tuner. Major component of slow tuner is electromechanical actuator based stepper motor/gear system/spindle & nut. Failures of the electromechanical actuators made significant impact on operation of the linear accelerators. Fermilab is designing linear accelerator for PIP II. 325MHz and 650MHz SRF cavities, which designed to work at PIP II linac, have large stiffness. FNAL and Phytron developed electromechanical actuator based on stepper motor/gear system/shaft as a component for tuners to serve SRF cavities for PIP II linac. Results of the cold test of the actuators prototypes mounted on the SRF cavity presented. Review of reliabilities for available on the market electromechanical actuator presented. | ||
