Observation of sub-GeV electrons mirrored by ultrathin crystalline Si

Observation of sub-GeV electrons mirrored by ultrathin crystalline Si

Detailed experimental studies are performed on the mirroring effect for 255-MeV electrons channeled through a 0.74-μm-thick Si crystal at the injector linac of the SAGA-LS facility. For the planar channeling alignment, deflection of the beam by 0.45 mrad is observed with 29% efficiency. The effect i...
