| Research Abstract |
When a charged-particle beam passes through a gap of a vacuum pipe, an electromagnetic field of the beam is radiated into free space out of the vacuum pipe. The frequency spectrum of the radiation spreads over microwave to millimeter wave region depending on the bunch length of the beam. These radiation spectrum, intensity, and spatial distributions in free space have been numerically investigated in detail depending on the bunch length. Based on the systematic calculations, the fundamental parameters have been optimized in order to fabricate a prototype detector, which is based on a Fabry-Perot resonator type interferometer with a wide band(10-50 GHz) and high sensitivity. The detector was successfully calibrated and it could be confirmed to fully meet the bunch length measurement for a single-bunch electron beam delivered from the KEKB injector linac.
