An ion source is a device that creates atomic and molecular ions. [1] Ion sources are used to form ions for mass spectrometers, optical emission spectrometers, ...
As a particle bunch travels around a cyclotron, two effects tend to make its particles spread out. The first is simply the particles injected from the ion source having some initial spread of positions and velocities. This spread tends to get amplified over time, making the particles move away from the bunch center.
They are a major source of iron and are mined for commercial use. [1] The main iron ores are from the oxide group consisting of hematite, goethite, and magnetite. The carbonate siderite is also typically mined. A productive belt of iron formations is known as an iron range. [2]

The direct-EI interface is a miniaturized interface for nano- and micro-HPLC in which the interfacing process takes place in a suitably modified ion source. Higher sensitivity, linearity, and reproducibility can be obtained because the elution from the column is completely transferred into the ion source. Using these two interfaces electron ...
An ion beam is a beam of ions, a type of charged particle beam. Ion beams have many uses in electronics manufacturing (principally ion implantation) and other industries. There are many ion beam sources, some derived from the mercury vapor thrusters developed by NASA in the 1960s. The most widely used ion beams are of singly-charged ions.
The short pulse induced molecular fragmentation may be used as an ion source for high performance mass spectroscopy. The selectivity provided by a short pulse based source is superior to that expected when using the conventional electron ionization based sources, in particular when the identification of optical isomers is required. [53] [54]
The figure shows the main components of an APPI source: a nebulizer probe which can be heated to 350–500 °C, an ionization region with a VUV photon source, and an ion-transfer region under intermediate pressure that introduces ions into the MS analyzer. The analyte(s) in solution from the HPLC flows into the nebulizer at a flow rate that can ...
