- The broad range of research topics investigated at SINQ requires not only a large zoo of neutron scattering instruments but also a large collection of sample environment devices. At present, any temperature between 100 mK to 1400 K, any magnetic fields up to 9 T and any high pressure up to 30 kbar may be achieved. The PSI-[Risų|http://www.risoe.dk/afm/index.htm] collaboration helped to complete the sample environment park in the direction to higher magnetic fields and very low temperatures for single crystals.

- * Two dilution cryostats for powder neutron diffraction were built in house. The two devices are to be used one after the other on the
- same instrument. This enables to change the sample on the instrument every 3 days with only a short loss of beam time.
- * From Risų we have a dilution stick for single crystals. They may be entered into a Helium-4 cryostat or into one of the
- [Oxford Instruments|http://www.oxford-instruments.com/] Cryomagnets MA02 and MA09.
