Conceptual Studies on a Beam Abort System for HADES — •Florian Marx for the HADES collaboration — Goethe-Universität Frankfurt

The physics cases studied with the HADES experiment at SIS-18 (GSI Darmstadt) require high beam intensities of several MHz well focused on a target. During the beam time, there is a risk of the beam not hitting the target but rather its surroundings, potentially harming the detectors and electronics. Reasons may be bad beam alignment or failure of guiding magnets for the particle beam. The aim of this work is to design and realize an FPGA based monitoring system, which is able to analyze the relevant hit rates in various detectors and compare them to a preset default. A dedicated algorithm can assess whether the rates significantly exceed the given limits and cause a possible thread for the detectors and/or electronics. As a results various follow-up actions can be triggered, including aborting the beam on a short time scale. This talk will present the implementation and first test results.
