AbstractThe helium cryogenic system at Spallation Neutron Source (SNS) provides cooling to 81 superconducting radio frequency cavities. To support the operation of the cryogenic facility, a highly reliable control system consisting of software, hardware, and Human Machine Interface (HMI) has been developed and improved during the first fifteen years of operation. Integrating the cryogenic control system with other subsystems of the SNS complex is an important aspect to the success of the operation. The operating experience, lessons learned and recommendations to consider for future facilities will be detailed in this paper.

Design Challenges

Kirkpatrick–Baez (KB) neutron supermirrors can efficiently focus polychromatic neutron beams to micrometre dimensions. The ultimate size is determined mainly by the perfection of the mirrors and by the size of the beam needed to have sufficient experimental signal. Nested or Montel KB mirrors can collect ∼2.6 times more beam than standard sequential KB optics, but require good figure perfection at the edge of one mirror. This paper describes the characterization of the figure errors over the important reflective portions of the two mirrors needed for a Montel focusing pair. The measurements are placed in context with theoretical predictions and are used to predict mirror focusing performance. Strategies to improve on the focusing of this class of optics are suggested and early results from these mirrors installed on the Spallation Neutrons at Pressure (SNAP) Beamline 3 at the Spallation Neutron Source (SNS) at Oak Ridge are presented.
