Abstract: The main issue of this paper is to introduce the application of phase lock loop (PLL) in superconducting RF technology. The voltage-controlled oscillator phase lock loop (VCO-PLL) can be used for locking the eigen frequency of the superconducting cavity. It can keep superconducting cavity resonant stably. In thispaper, the principle of the cavity locking by the VCO-PLL is verified by a simulation, which is done by using NI-Labview software. The simulation result shows that the different gain of the PLL system can impact the locking situation of the whole system. In the test stage, the locking test plant is set up and passed validation. Finally, at the low temperature test stage, the frequency of the IMP-HWR010 superconducting cavity is locked by the test plant. The frequency change with helium pressure of the cavity is about 0.73 Hz/Pa.
