Superheated Drop as a Neutron Spectrometer
Superheated drops are known to vaporise when exposed to energetic nuclear radiation since the discovery of bubble chamber. The application of superheated drops in neutron research specially in neutron dosimetry is a subject of intense research for quite sometime. As the degree of superheat increases in a given liquid, less and less energetic neutrons are required to cause nucleation. This prope...
متن کاملDrop impact on superheated surfaces.
At the impact of a liquid droplet on a smooth surface heated above the liquid's boiling point, the droplet either immediately boils when it contacts the surface ("contact boiling"), or without any surface contact forms a Leidenfrost vapor layer towards the hot surface and bounces back ("gentle film boiling"), or both forms the Leidenfrost layer and ejects tiny droplets upward ("spraying film bo...
متن کاملExperiments with a Slow Neutron Velocity Spectrometer
Neutron bursts were produced by modulation of the arc source of a small cyclotron. Neutrons subsequently slowed down in paraffin were detected by a BF3ionization chamber and linear amplifier. Modulation of an additional amplifier allowed the counting of all detected. neutrons as well as those arriving in a specified time interval. Time of flight experiments were carried out at 3.0 meters with "...
متن کاملNIST Calibration of a Neutron Spectrometer ROSPEC
A neutron spectrometer was acquired for use in the measurement of National Institute of Standards and Technology neutron fields. The spectrometer included options for the measurement of low and high energy neutrons, for a total measurement range from 0.01 eV up to 17 MeV. The spectrometer was evaluated in calibration fields and was used to determine the neutron spectrum of an Americium-Berylliu...
متن کاملMiniature Neutron-Alpha Activation Spectrometer
We are developing a miniature neutron-alpha activation spectrometer for in-situ analysis of chem-bio samples, including rocks, fines, ices, and drill cores, suitable for a lander or Rover platform for Mars or outer-planet missions. In the neutron-activation mode, penetrating analysis will be performed of the whole sample using a y spectrometer and in the ex-activation mode, the sample surface w...
