Abstract

Abstract

The key to design magnetic alloy (MA) loaded cavity is to test and research the performance parameter of the MA core. Using the resonant circuits, we have tested the performance parameters of the domestic MA core, including the permeability, Q value and shunt impedance. Test results show that the Q value of the MA core is low while the change caused by frequency is not obvious. The magnetic permeability is high and decreases with frequency increase while the shunt impedance increases with frequency increase. Within the working temperature from 0 ℃ to 100 ℃, the performance parameter of the MA core changes very little. The analysis of the performance test data of the MA core provides important technical indexes for the design of microwave power source and LLRF system.
- coaxial cavity,
- magnetic alloy ring,
