We investigate the ionisation processes of rubidium in strong infra-red laser fields and in the electromagnetic field of a 400 GeV energy proton beam via ab initio calculations.We reduce the latter phenomena to photoionisation with the Weizsäcker–Williams method. The bound and the continuum states are described with Slater orbitals and Coulomb wavepackets, respectively. The bound state spectrum has been calculated with the variational method. Using this approach, ionisation processes can be studied successfully [1]. We investigate the effects of the shape and the parameters of the pulse to the photoionisation cross section. These calculations may provide a valuable contribution at the design of laser and plasma based novel accelerators, e.g. the CERN AWAKE experiment [2].
