Description
Based on the expertise in high-intensity electron accelerator technology at the Mainz Microtron MAMI, a new accelerator MESA (Mainz Energy-Recovering Superconducting Accelerator) is currently under construction at the Institute for Nuclear Physics at Johannes Gutenberg University Mainz. MESA will be operated at low beam energies below 155 MeV, but at high inensities of at least 1 mA of beam current. The high intensity will provide the basis for a series of precision experiments in the fields of hadron and low-energy particle physics. In this talk, highlights of the research programme at MESA will be discussed including a new measurement of the electroweak mixing angle at low momentum transfer (P2 experiment), measurements of the electromagnetic form factors of the nucleons (MAGIX experiment) as well as searches for dark sector particles (the MAGIX and the beam dump experiment BDX). These experiments will be operated either in the extracted beam mode of MESA (P2 and BDX) or in the energy-recovering mode (MAGIX) of the accelerator, in which for the first time a high-intensity energy-recovering beam will be operated in conjunction with a gas internal target.
