Magnet simulations for HISPEC position tracking detector — •Michael Armstrong and Gereon Hackenberg — University of Cologne

Future in-flight spectroscopy of radioactive heavy ion beams in HISPEC (HIgh resolution in-flight SPECtroscopy) experiments at GSI/FAIR will require highly precise beam tracking and timing [1]. For these experiments a pair of Secondary Electron Detector (SED) using Multi-Channel Plate (MCP) detectors are being designed to fulfil these requirements. In order to achieve the necessary precision the MCP's must be enveloped in a homogenous 100 gauss magnetic field. In this poster the design of a prototype permanent magnet is presented including simulations of the magnetic field it should be capable of providing.

This work was supported by GSI under F&E grant KJOLIE1820.
