New data on the proton form factor at low-Q^2 from Mainz using a cluster/gas-jet target

Motivated by the decade old, still not fully resolved proton radius puzzle and the striking difference in low-Q^2 form factor extractions between the PRad and Mainz measurements, the A1 collaboration measured several kinematic points in the overlap region between the two data sets. To improve on previous measurements, a cluster/gas-jet target and additional halo shielding and veto detectors were installed. In the talk, we discuss these upgrades and the results of the first measurements.
