Neutron velocity distribution from a superthermal solid 2 H 2 ultracold neutron source
نویسنده
چکیده
We have determined for the first time the velocity distribution of neutrons from a solid H2 ultracold neutron (UCN) source. The spectrum rises sharply above 4.5m/s and has a maximum around 7m/s after transport in an 8m long guide. The number of neutrons in the UCN velocity range (< 7m/s) may be increased by a factor of two by placing the experiment 1m above the UCN source level.

An apparatus to control and monitor the para-D2 concentration in a solid deuterium, superthermal source of ultra-cold neutrons
In a recent investigation of solid D2 as a UCN source[1], it was surmised that the yield of UCN is correlated with the spin states of the deuterium molecules. Subsequently, detailed neutron scattering calculations and measurements of the UCN lifetime in mixtures of paraand ortho-deuterium quantitatively verified this conjecture.[2,3,4,5,6] The work we report here was motivated by our attempt to...
متن کاملUltracold-neutron infrastructure for the gravitational spectrometer GRANIT
The gravitational spectrometer GRANIT will be set up at the Institut Laue Langevin. It will profit from the high ultracold neutron density produced by a dedicated source. A monochromator made of crystals from graphite intercalated with potassium will provide a neutron beam with 8.9 Å incident on the source. The source employs superthermal conversion of cold neutrons in superfluid helium, in a v...

متن کاملMeasurements of ultracold-neutron lifetimes in solid deuterium.
We present the first measurements of the survival time of ultracold neutrons (UCNs) in solid deuterium (SD2). This critical parameter provides a fundamental limitation to the effectiveness of superthermal UCN sources that utilize solid ortho-deuterium as the source material. These measurements are performed utilizing a SD2 source coupled to a spallation source of neutrons, providing a demonstra...
متن کاملEstimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user
Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
