The MESA Experimental Program: A Laboratory for Precision Physics with Electron Scattering at Low Energy
2021
A rich experimental program is currently being prepared at a new laboratory for high-intensity electron scattering at the Mainz Energy recovering Superconducting Accelerator (MESA). The physics pro...

POLARIZED ELECTRONS AND POSITRONS AT THE MESA ACCELERATOR
2011
We suggest starting an accelerator physics project called the Mainz Energyrecovering Superconducting Accelerator (MESA) as an extension to the experimental facilities at the institute for nuclear physics. MESA may allow us to introduce an innovative internal target regime based on the ERL principle. A second mode of operation will be to use an external polarized electron beam for parity violating experiments. Furthermore, MESA could also allow us to establish a CW source of polarized positrons.
Preaccelerator concepts for an energy-recovering superconducting accelerator
2021
In this paper we compare two concepts of a preaccelerator for the energy-recovery linac MESA: a hybrid injector that combines normal conducting and superconducting technology and a fully normal conducting injector. The particle source delivers polarized electrons at 100 keV. Thus the first accelerating section has to be of a graded-β kind. The graded-β section is designed with a final energy exceeding 1 MeV so TESLA-type nine-cell resonators can be used as superconducting cavities. The final energy of the preaccelerator shall be 5 MeV to avoid neutron production in the beam dump of the energy-recovery linac.
