Miniscat is a compact atom scattering beamline designed to be compartible with the He-3 SpinEcho to perform preliminary measurements as well as independent atom diffraction experiments. The experiment is performed under high and ultra-high vacuum and involves scattering a beam of He-4 atoms off the sample. A custom sample transfer (compatible with the SpinEcho) is used for mounting samples within the scattering chamber and gaseous, liquid, and metallic species may be dosed in the scattering chamber. The apperatus has largely been built in house and therefore has a number of bespoke components.

Item | Specification |
---|---|
Sample temperature range | 20K – 1100K |
Sample chamber vacuum range | 1e-10mbar – 1e-7 mbar |
Incident beam energy | 8meV-65meV |
Beam spot size | ~3mm diameter |
The substrate must be a single crystal of at least 5mm dimension. Dosing of gaseous, liquid, and metallic species is possible (please contact if you have a specific requirement). In general substrates should be able to withstand temperatures >100C. The sample mounting/sample transfer is not compatible with other techniques, therefore the substrate must be mounted in atmosphere on the custom sample cartridge.
Experiments are unlikely to be completed in less that 1wk of beam time.
