Miniature 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...
متن کاملDesigning an Am-Be miniature neutron source
Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...

متن کاملMiniature, sub-nanometer resolution Talbot spectrometer.
Miniaturization of optical spectrometers has a significant practical value as it can enable compact, affordable spectroscopic systems for chemical and biological sensing applications. For many applications, the spectrometer must gather light from sources that span a wide range of emission angles and wavelengths. Here, we report a lens-free spectrometer that is simultaneously compact (<0.6 cm<s...
متن کاملA miniature mass spectrometer for chemical and biological sensing
An experimental study has been carried out using a Miniature Quadrupole Mass Spectrometer (MicroQuad) for gas analysis. Conventional quadrupole rods have been replaced with a micromachined mass filter made from silicon with Au metallised specially drawn glass fibres of length 30 mm and diameter 0.5 mm. A standard hot filament ion source and both Faraday detection and a channel electron multipli...
