Microwave plasma heating by cavity modes at electron cyclotron and lower hybrid frequencies

Description
Plasma heating by radio frequency (RF) in the electron cyclotron and lower hybrid frequency ranges has been studied using Langmuir and magnetic probes in the linear mirror machine, LISA. It has been shown that global modes have been excited. The plasma has been heated by the electron cyclotron resonance and linear mode conversion at r = ±3 cm using a RF source of 2.45 GHz and 1 kW. When an additional FR source of 30 MHz and 350 W was introduced, it heated the plasma via the lower hybrid resonance at r = ±5 cm. An increase in overall electron temperature and plasma density has been observed when both sources were present
