Cryogenic Tunable Microwave Cavity at 13 GHz for Hyperfine Spectroscopy of Antiprotonic Helium
For the precise measurement of the hyperfine structure of antiprotonic helium microwave radiation of 12.9 GHz frequency is needed, tunable over ±100 MHz. A cylindrical microwave cavity is used whose front and rear faces are meshed to allow the antiprotons and laser beams to enter. The cavity is embe...
