MAC is a multi-purpose chamber placed at the direct beam line of the HHG source. It will provide a flexible environment for experiments in coherent diffractive imaging and AMO physics. The MAC chamber can accommodate different types of targets and can be equipped with a range of diagnostic devices. It will be possible to perform pump-probe experiments with two HHG beams in the MAC chamber or to use an HHG beam and a pump beam (with a tunable wavelength from the UV range and visible to the MIR or THz range).
Targets
There will be a particle injector capable of delivering a collimated beam of biological samples or artificial nano- and micro-particles with sizes in the range from tens of nanometers to a few micrometers. The injector will be employed predominantly for coherent diffractive imaging. It will also be possible to use atomic or molecular beams for AMO experiments or a cluster source delivering clusters with sizes starting from a few nanometers.
Diagnostics
A variety of detectors and diagnostics can be used at the MAC chamber. Imaging detectors for scattered radiation from the sample will be used for coherent diffractive stereo-imaging experiments. Electron and ion time-of-flight spectrometers will be provided to detect charged particles. In addition, velocity map imaging will allow mapping of the electron velocity on the position on the camera, thus enabling angular-resolved and energy-resolved photoelectron spectra to be captured. Users will also be able to bring their own diagnostics for their specific experiments.
Optical capabilities
MAC will be placed at the direct HHG beam lines that will deliver photons with energies in the range of 10–100 eV. It will be possible to use two HHG beams in the MAC chamber for two-beam coherent diffractive imaging or for pump-probe experiments in the VUV/XUV range. In addition to the HHG beams, a synchronized pump beam with a tunable wavelength from UV and visible to MIR or THz will be available for experiments.
