Abstract

This note is motivated by preparations of a new ep elastic scattering experiment in the low transfer momentum region to be carried out in the 720 MeV electron beam of the Mainz Microtron MAMI. This experiment will use an innovative method allowing for detection of recoil protons in coincidence with the scattered electrons. The goal is to measure the ep differential cross sections in the Q² range from 0.001 GeV² to 0.04 GeV² and to determine the proton charge radius with sub-percent precision.
