The Mainz Energy-Recovering Superconducting Accelerator (MESA) is currently under construction at Johannes Gutenberg-University Mainz. It is a mulit-turn ERL for particle and nuclear physics experiments. As the centerpiece for acceleration a turn-key solution was chosen. Two modified ELBE/Rossendorf-type cryomodules will accelerate the electrons up to 25 MeV per turn. The modules will be operated in cw at an accelerating gradient of 12.5 MV/m. The modifications comprise of an integration of a piezo tuner system and a better thermal connection of the HOM antennas for allowing high beam current in cw operation. Site acceptance tests of both modules have been carried out at the Helmholtz Institute Mainz (HIM) and by now the first cryomodule was successfully operated at design gradient and could be accepted. This talk will cover the experiences with a turn-key solution made by industry and will show the results of the site acceptance tests.
