Measurement of neutron whispering galley at monochromatic neutron beam
We continue a series of precision measurements of neutron whispering gallery motivated by the possibility to provide competitive constraints for fundamental short-range forces. On the other hand, this phenomenon can serve at certain conditions to study surface. Currently, the precision is limited by the neutron wavelength calibration, which is of the order of 10^(-3) in the time-of-flight mode of measurement at D17 instrument. We are going to use a monochromatic neutron beam at SuperADAM to further improve the precision of this calibration. Preliminary measurement showed that the count rate in the monochromatic mode at SuperADAM is sufficiently high, the mean wavelength of 5.2A corresponds nicely to our range of interest and the spectrum band width of 0.5% should allow to resolve the interference lines on one hand and provide high statistics on the other hand. The proposed experiment consists of a few measurements of the neutron whispering gallery at different parameters also a dedicated calibration of the neutron wavelength with the precision 10^(-4) using a new compact time-of-flight device developed for GRANIT.
