33Gas chromatography-mass spectrometry — (GC MS) is a method that combines the features of gas liquid chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC MS include drug detection, fire investigation, environmental analysis,… …
34Hollow cathode lamp — A hollow cathode lamp (HCL) is type of lamp used in physics and chemistry as a spectral line source and as a frequency tuner for light sources such as lasers.An HCL usually consists of a glass tube containing a cathode, an anode, and a buffer gas …
35Magnetosphere of Jupiter — Discovery[1] Discovered by …
36A Large Ion Collider Experiment — ALICE (A Large Ion Collider Experiment) is one of the six detector experiments being constructed at the Large Hadron Collider at CERN. It is optimized to study heavy ion collisions. Pb Pb nuclei collisions will be studied at a centre of mass… …
37geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… …
38Ion thruster — An ion thruster is a form of electric propulsion used for spacecraft propulsion that creates thrust by accelerating ions. Ion thrusters are characterized by how they accelerate the ions, using either electrostatic or electromagnetic force.… …
39Neutron radiation — is a kind of ionizing radiation which consists of free neutrons. A result of nuclear fission or nuclear fusion, it consists of the release of free neutrons from atoms, and these free neutrons react with nuclei of other atoms to form new isotopes …
40Neutron generator — Neutron generators are neutron source devices which contain compact linear accelerators and that produce neutrons by fusing isotopes of hydrogen together. The fusion reactions take place in these devices by accelerating either deuterium, tritium …
