	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under cooperative agreement DE-SC0000661. Updates to the FRIB β=0.53 half wave resonator (HWR) design have provided an opportunity to test new buffered chemical polish (BCP) flow control techniques. New processing fixtures have been fabricated and used to process the FRIB β=0.53 HWR. This paper will present details of the fixture mechanical design iterations, the resulting BCP flow simulations, a qualitative evaluation of the agreement between simulations and measured results, and developments in process validation techniques.
