Saxon}, title = {Commissioning the Felix Bunching System}, abstract = {The FELIX injector consists of a thermionic triode gun driven at 1 GHz, a 1 GHz subharmonic prebuncher, and a travelling wave (3 GHz) buncher. Further acceleration will be achieved with two identical constant-gradient, travelling-wave (3 GHz) linacs. The buncher, which provides an exit energy of 4 MeV, has the feature that an unambiguous relation between the particle phase and energy is established. In this article we report our experiences in commissioning the bunching system. This includes a discussion of the gun characteristics, emittance measurements with and without rf modulation, and investigations of the achievable pulse length behind the gun.}, year = {1991}, journal = {Nuclear Instruments & Methods in Physics Research Section a-Accelerators Spectrometers Detectors and Associated Equipment}, volume = {304}, number = {1-3}, pages = {173-176}, month = {Jul 1}, isbn = {0168-9002}, doi = {10.1016/0168-9002(91)90843-f}, language = {eng}, }
