The Spallation Neutron Source

• The SNS will begin operation in 2006

• At 1.4 MW it will be ~8x ISIS, the world’s leading pulsed spallation source

• The peak neutron flux will be ~20–100x ILL

• SNS will be the world’s leading facility for neutron scattering

• It will be a short drive from HFIR, a reactor source with a flux comparable to the ILL

Neutron Choppers

• Fabrication and assembly of T0 chopper for powder diffractometer underway.

• Five 60-Hz bandwidth choppers have been delivered by Astrium, and have completed testing in the chopper lab at Argonne.

• Second procurement for 60-Hz bandwidth choppers has been awarded to Revolve. These will be magnetic bearing choppers.

BW Choppers for Backscattering Spect.


Sample Environment Activities

• Standards

– Documented standards for sample environment mechanical interfaces to instruments

– Communication protocols developed and standardized

– Functioning communication system tested

• Prototype development– Procuring several equipment items to develop

sample holders, cryostat tails, etc

– SBIR/STTR with Containerless Research, Inc to develop automated sample changing at low and high temperatures

– Developing rapid-change refrigerator in collaboration with Penn State


Sample Environment Activities – cont’d

• Basic suite of general sample environment equipment will be procured in FY06-FY07 using operating budget

– Inventory will be adequate to meet all needs for standard sample environments

– Operating staff adequate to support needs for all operating instruments will be ramped up beginning in FY2005

• Working with user groups to identify needs and pursue development of equipment for specialized sample environments

– White paper and draft policy on magnetic field interference issues

– Self-compensated high-field magnets


Analysis Software

• SNS is assuming an active role in the development of data analysis software

• The NESSI workshop to document requirements for such software was held at SNS October 13-15, 2003

• Draft requirements document prepared

• SNS team leader for scientific computation (Steve Miller) on board

• Preliminary implementation plan prepared

• Extensive international collaboration

• Part of team is already at work
