Status of the MESA ERL project* — •Florian Hug — Johannes Gutenberg-Universität Mainz

MESA is a recirculating superconducting accelerator under construction at Johannes Gutenberg-Universität Mainz, which will be operated in either external beam or ERL mode. After completion, it is planned to be used for high precision particle physics experiments. The operating cw beam current and energy in EB mode is 0.15 mA with polarized electrons at 155 MeV. In ERL mode a polarized beam of 1 mA at 105 MeV will be available. In a later construction stage of MESA the beam current in ERL-mode may be upgraded to 10 mA (unpolarized). Civil construction and commissioning of components like electron gun, LEBT and SRF modules have been progressed already. In this contribution we give a project overview including the accelerator layout, the current status and an outlook to the upcoming construction and commissioning steps.
