The SwissMX has currently only been commissioned to accept two styles of fixed-target: the PSI MISP (MIcro-Structured Polymer) and the MPI SOS (Sheet-On-Sheet) chip (Doak et al., 2018). The MISP-chip is composed of an array of apertures in defined locations in a similar style to the Oxford (Horrell et al., 2021) and HARE chips (Mehrabi et al., 2020). The MISP-chips can be fabricated in either a clear or an opaque polymer, with the only latter being compatible with pump-probe measurements. The SOS chip by comparison is made by carefully sandwiching a sample between two sheets of polymer film and are ideal for samples of limited volume in viscous media such as LCP. Liquid-crystal samples will need to be embedded in a moderately viscous medium to be used effectively. Please indicate in the DUO which chip or both you would like to use.
The SwissMX is capable of both SFX and nanosecond resolution SFX pump-probe measurements. The endstation can be fibre-coupled to an EKSPLA nanosecond OPO and the pump-probe measurements have been commissioned using the opaque MISP chips. Pump-probe is only possible using these chips.
Our standard SFX beamtime configurations are: X-ray photon energy of 12 keV with standard bandwidth (0.15 % SASE), nano-second laser excitation between 410 nm - 700 nm (if required), Jungfrau 8M detector and either MISP or SOS chips. Max beamtime length will be 2 days (6 shifts). Please indicate if you would only like 0.5/1 shifts for non-pump-probe SFX measurements.
