A test set-up was built at Helmholtz-Insitut Mainz (HIM) to conduct a feasibility study. One of the main goals of the test set-up is to evaluate the gun design proposed by TSL (Uppsala) with respect to vacuum handling, electric and magnetic fields, and the resulting beam parameters. Another purpose of the set-up is to reduce recuperation losses to less than 10⁻⁵. To measure this quantity and to mitigate collection losses, a Wien filter has been designed and installed. Beam diagnostics will be carried out with a COSY-style beam position monitor. The latest progress of the project is presented.
