I have designed the neutron switch, figure (a, c), working under ultra high vacuum (UHV) conditions, to achieve high neutron densities at UCN experiments at low noise.
With my design a transmission of up to 95% is achievable for a guide diameter of 50mm with an 60° angular deflection and 70mm radius (see figure (b).
Whereas, by usage of simulations and my cutting edge manufacturing technology, as well as, coating knowledge a leakage of (0.6 ± 0.2) × 10e−5 is possible.
These goals are achieved together with other experimenter friendly requirement as
- high robustness of stainless steel (SS) at lowest possible weight < 10kg of fully assemblies
- repositioning and easy SW handling
- Operation in any three dimensional alignment
For further projects also shutters have been designed fulfilling the same requirements. Also more than 3 way switches are possible. Further information on the switch can be found in my master thesis. You can also contact me. I am happy to answer your questions and help you with your problem.
