Description
A redesign of the injector beamline for the S-band linac at ELSA is underway, including the replacement of the existing electron gun by a hybrid gun that combines thermionic emission and thermally assisted photoemission in a single setup. The goal is to offer a new single-bunch injection mode alongside the long pulse mode already provided by the current gun. Measurements have been conducted to verify this emission technique using caesium dispenser cathodes.
Another step in the scope of the project is the replacement of the current prebuncher cavity. A new design has been worked on and already undergone different tests of quality factor and bunching capabilities.
The development of a dedicated test stand is currently being carried out to facilitate more detailed studies and serve as a prototype for the future injector section. Recent work has concentrated on the lattice and magnet design, as well as on evaluating suitable beam-diagnostic instrumentation.
