Research Abstract	A new type of high brightness lithium ion beam for plasma diagnostic is under development. The ion source is heated by radiation from SiC, which is used as an microwave absorber. The target of this research was to heat the ion source of 50 mm diameter up to 1,500℃ using a microwave source of 1.3 kW/2.45 GHz, which is not achieved yet. The achieved temperature so far was 1,200℃.
