Longitudinal Dispersion Measurements at the S-DALINAC Using RF Monitors*
Presented by Florian HUG
The superconducting electron accelerator S-DALINAC is a recirculating linac with two recirculations. Currently the effect of different longitudinal working points on the resulting energy spread of the linac is investigated in order to provide an electron beam with a lower energy spread for the experimental setups in future. For this purpose it is necessary to know the properties of the beam transport system exactly, especially the effects of different settings on the longitudinal phase space. We will report on a new setup for the measurement of the longitudinal dispersion in the recirculation arcs using rf phase measurements on beam intensity monitors and the time of flight method.
