摘要:

The first experimental demonstration of the physical mechanism underlying multi‐electron‐beam Cherenkov free‐electron lasers has been carried out. Electron beams of a total beam current of 280 A at 500 kV were introduced into a multi‐dielectric cavity and stimulated Cherenkov radiation of 1.7 MW at 33.4 GHz was generated. The interaction efficiency was about 1.2%.
