We demonstrate a sensor that measures wavefronts of multiple extreme ultraviolet wavelengths simultaneously. By incorporating transmission gratings into the apertures of a Hartmann mask, we can record wavefront information for series of discrete harm

It is nearly 10 years since a measurement in muonic hydrogen by the CREMA collaboration resulted in a surprisingly small proton charge radius [1]. Since then, an increasing number of high-precision atomic physics experiments have been started (and pe
