APXPS proposal submission
As there are two complimentary APXPS beamlines at MAX IV, many proposals could be carried out at either HIPPIE or SPECIES. Such proposals can therefore be submitted with a preference of beamline, which is recommended if a proposal would benifit from specific capabilities of either beamline (e.g. photon or sample environment requirements), or without a preference in which case the proposal will be considered for both beamlines.
Scanning probe microscopy
If your experiment would benefit from UHV scanning probe microscopy (STM or NC-AFM) of your surfaces, samples from HIPPIE can be transferred via vacuum suitcase to an Omicron VT SPM. For more information, refer to the Scanning Probe Microscopy lab webpages.
HIPPIE sample requirements
HIPPIE uses slightly custom “flag” style sample plates. These can have a hole in the plate to allow for direct heating of the sample via an infrared laser and a thermocouple electrical contacts for direct measurement of the sample temperature. Samples are typically mounted on the plates using clips, that can either be attached to the plate by spot welding or screws. Typically, samples are approximately 8 x 8 mm, with a maximum size of 10 x 10 mm (but this is more challenging to mount).
