Sample environment at the China spallation neutron source.

The progress in sample environment at the China Spallation Neutron Source (CSNS) is presented. During the past two years, the Sample Environment group (SE Group) has made substantial efforts towards the procurement, design, development and maintenance of a series of sample environments for the three commissioning instruments. The equipment includes cryostats, an 3He insert, magnets, furnaces, continuously-loaded pressure cells, clamp cells, a gas handling panel, automatic sample changers, etc. The SE Group also constructs and maintains three user laboratories for sample preparation, characterization and complimentary analysis. Future developments are also briefly described. [ABSTRACT FROM AUTHOR]
