Paper Abstract

We purpose a new method for 1s-2s spectroscopy of atomic hydrogen. Our method is based on a new detection scheme, utilizing a three-photon ionization to obtain a signal correspondent to the excitation of atoms into 2s state. We report about assembling and test of a proton detection system for this measurement. To measure a second order Doppler shift we purpose a delayed detection scheme. Using this method we plan to reduce the uncertainty of the absolute frequency measurement to the 10-15 domain.
