Overview over the experimental progress of the dechirper planned at ELBE — •Franziska Reimann1, Ursula van Rienen1, Peter Michel2, and Ulf Lehnert2 — 1Universität Rostock, Institut für Allgemeine Elektrotechnik; Rostock, Germany — 2Helmholtz-Zentrum Dresden-Rossendorf; Dresden-Rossendorf, Germany
Dielectrically lined rectangular waveguides provide the possibility to passively reduce the energy spread of particle beams via the interaction of the beam and its own wakefield ([*],[**]). Such a device is commonly referred to as a dechirper, and is currently used as a prototype for perspective studies at the Helmholtz-Zentrum Dresden-Rossendorf. During the beam time in the second half of the year 2016, an 80 cm long structure was inserted into the beam line and tested regarding its dechirping effect on the beam. In this work, we present the geometry of the dechirper and report on the status of the prototype and the first measurements made with it.
This work is supported by the Federal Ministry for Research and Education BMBF under contract 05K13HR1.
