The aim of the AMO beamline at ASTRID2 is to conductphoto-physics investigations of molecular and atomic ions.
In order to provide the photons a collimated-beamplane-grating monochromator (cPGM) equipped with two variable-groove-depth (VGD) gratings is designed. Particular emphasis is paid to the transmission characteristics, including efficient suppression of higher diffraction orders and the provision of a high-flux (low-resolution) mode of operation. The beamline is sourced by a P53 undulator that provides photon from 5 eV to >150 eV. Single-bunch operation of the ASTRID2 is envisaged for timing experiments.
A novel dedicated ion-beam end station will allow for either merged- or crossed-beams experiments with a stored beam of fast-moving ions. Moreover it is possible interact with ions stored in an rf trap. The end station will offer several detection schemes, including, momentum-resolved measurements of both charged and neutral fragments as well as electrons.
