Abstract
The current paper deals with analytical bunch compression studies for FLUTE whose results are compared to simulations. FLUTE is a linac-based electron accelerator with a design energy of approximately 40 MeV currently being constructed at the Karlsruhe Institute of Technology. One of the goals of FLUTE is to generate electron bunches with their length lying in the femtosecond regime. In the first phase this will be accomplished using a magnetic bunch compressor. This compressor forms the subject of the studies presented. The paper is divided into two parts. The first part deals with pure geometric investigations of the bunch compressor where space charge effects and the backreaction of bunches with coherent synchrotron radiation are neglected. The second part is dedicated to the treatment of space charge effects. The upshot is that the analytical results in the two parts agree quite well with what is obtained from simulations. This paper shall form the basis for future analytical studies of the FLUTE bunch compressor and of bunch compression, in general.
Highlights
FLUTE is a linac-based electron accelerator which is presently being built at the ANKA Synchrotron Radiation Facility at the Karlsruhe Institute of Technology [1,2,3,4,5,6,7,8,9,10,11,12]
The acronym FLUTE stands for the German expression Ferninfrarot Linac- Und Test-Experiment translated to English as “Far-infrared Linac- and Test Experiment.”
Analytical studies for bunch compression at the future linear accelerator FLUTE were performed whose results were compared to the simulation output of the tool Astra
Summary
[13] it was shown theoretically that by applying an external oscillating electric field to a sample of graphene, it is possible to produce higher harmonic modes At room temperature this effect may occur for frequencies in the THz regime. The applications have two characteristics in common: they need high electric and magnetic field strengths (in the order of magnitude of MV=m and several hundred kA=m, respectively) and they happen on ultrashort time scales (picoseconds) These properties can be provided by pulses of coherent synchrotron radiation in the THz regime (see, e.g., [4]). Due to space charge effects and the self-interaction of bunches with their own coherent radiation field a compression of bunches to a length of several femtoseconds is a challenging task— for FLUTE but for a number of other future machines as well.
