In August 2018, our company successfully completed the development of two sets of IH Buncher cavities for MSU FRIB (13–22 MeV, 161 MHz). In October, the company assigned technical staff to install and conduct testing on the cavities at MSU FRIB. Currently, the vacuum and frequency test results of the cavities have met the technical requirements, and all installation dimensions conform to the on-site standards for installation.
