A Measurement System for Channeling Radiation at High Charge Densities* — •W. Bayer, H. Genz, A. Richter, and A. Zilges — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany
The objective of the project is to investigate if channeling
radiation (CR) can be produced in crystals by high electron bunch charges,
a topic of crucial importance in the realm of plasma acceleration
[1]. It has been suggested to use channeling in solid state plasma
acceleration in order to minimize beam spread [2]. So far, CR has been
investigated in detail mainly for Si crystals [3,4]. Since diamond crystals
may be even more suitable the current project is using diamond
crystals and a radiation detector and data acquisition system that allows
to
record the spectral distribution of the CR in order to investigate the
electron-crystal interaction in more detail. The system must be able
to handle more than 106 counts per second. First measurements
have been performed in order to test the system.
