Abstract
The Extended Q-range Small-angle Neutron Scattering Diffractometer (EQ-SANS) instrument at the spallation neutron source (SNS), Oak Ridge, Tennessee, incorporates a 69Â m3 detector vessel with a vacuum system which required an upgrade with respect to performance, ease of operation, and maintenance. The upgrade focused on improving pumping performance as well as optimizing system design to minimize opportunity for operational error. This upgrade provided the following practical contributions:
- Reduced time required to evacuate from atmospheric pressure to 2Â mTorr from 500 to 1000Â min to 60-70Â min
- Provided turn-key automated control with a multi-faceted interlock for personnel and machine safety.
