Description
Fermilab’s PIP-II project seeks to enhance its proton beam capabilities for scientific research by modifying the existing synchrotrons and replacing the linear accelerator with a superconducting linear accelerator. To mitigate risks in technology readiness and prepare for operational maintenance, test stands of various complexities were built. Many of the RF components, subsystems, and systems have been tested further reducing risk. The conversion of the former Tevatron RF gallery into a test area has allowed for 162.5MHz and 650MHz circulator, SSA, and amplifier module testing. In the RF test cave for warm cavities, both the prototype dual-tetrode 52-53MHz and prototype 30-53MHz ferrite loaded cavities were fully characterized. At the single cavity SRF test cave, individual SRF cavities continue to be tested individually before string assembly. The PIP-II Injector Test (PIP2IT) facility was used to successfully test the Linac components with beam up to 10MeV. These tests included the 162.5MHz RFQ, buncher cavities, eight-cavity half wave resonator cryomodule (HWR), and the 325MHz eight-cavity prototype single spoke resonator cryomodule (pSSR1). After its beam run, this facility was converted into the test bed for all future 325MHz and 650MHz cryomodules. All of these test facilities will be utilized for quality control testing and the advancement in the TRL of key high-risk technologies.
