Abstract :
Gyrotron FU CW V operating at the fundamental cyclotron resonance is used for measurement of hyperfine structure on positronium. The gyrotron delivers high power radiation with the frequency of 203.2 GHz and output power of 0.7 kW under CW operation mode. This radiation can be used for direct measurement of energy level transition of positronium, because expected energy level difference is near 203.4 GHz.
