Measurements at the new external beam line at ELSA with a Mimosa telescope — •Yannick Dieter, Tomasz Hemperek, Toko Hirono, Fabian Hügging, Jens Janssen, Hans Krüger, David-Leon Pohl, Norbert Wermes, and Jochen Dingfelder — Physikalisches Institut der Universität Bonn

A new beam line was constructed at the electron accelerator ELSA (Elektronen-Stretcher-Anlage) in Bonn to provide a test area for detector tests. The accelerator delivers an electron beam of a variable energy of maximum 3.2 GeV with an available current of 100 pA which corresponds to a rate of about 600 MHz. The extraction can be steered with a feedback scintillator to achieve a constant beam rate. To test new detectors the ANEMONE (A Nice Eudet Mimosa Bonn Telescope) beam telescope which was developed by the EUDET project is installed. It consists of six Mimosa26 sensors and one ATLAS FE-I4 module. Besides a high-precision beam tracking, the telescope allows for a high-rate time stamping. In this talk, a setup to take test beam data with the telescope and the analysis of the recorded test beam data are presented, with a focus on beam characteristics like rate stability, beam size and divergence will be presented.
