The motorised orifice system for the PANDA Beam Dump: programming and implementation of a control software in a local EPICS Slow Control System — •Liridon Deda, Daniel Bonaventura, Philipp Brand, and Alfons Khoukaz for the PANDA collaboration — Institut für Kernphysik, Universität Münster, 48149 Münster, Germany

The planned PANDA experiment at the future HESR ring will be vital for investigating the mysteries of hadron physics at FAIR in Darmstadt. A high target thickness of more than 10¹⁵ atoms/cm² will be crucial for the p−p interation studies at PANDA. The cluster-jet target system for the PANDA experiment, already achieved these required target thickness in PANDA geometry, i.e. in a distance of more than 2 m from the jet nozzle. Providing such a target thickness at the interaction point, requires to effectively remove the target beam after the interaction point via a beam dump. In order to mitigate any gas backflow, a multi-stage beam dump system with differential pumping has been implemented. Each stage comprises adjustable orifices, allowing for modification of the orifice width and position, in one direction. Additionally, the orifice control system and its implementation into the local EPICS slow control system is presented. Furthermore, the orifices are equipped with two motors each, controlled through a robust CAN-Bus communication system ensuring resistance against electrical disturbances and electromagnetic interference. The setup and its performance will be presented and discussed.

This project has received funding from BMBF (05P21PMFP1).
