A 166.667 MHz Proof-of-Principle (PoP) superconducting RF cavity has been fabricated by IHEP for the High Energy Photon Source Test Facility (HEPS-TF) [1]. After a series of post-processing including chemical etching (BCP), high temperature heat treatment, High Pressure water Rinsing (HPR) and 120°C baking, the cavity was cold RF tested and reached Epeak=86.5 MV/m and Bpeak=132.1 mT with Q0=5.1×〖10〗8 at 4.2K. The cavity was RF tested again at 2K, and reached Epeak=85.5 MV/m and Bpeak=131.1 mT with Q0=3.3×〖10〗9.
