Scintillation dectectors use a solid or liquid material whose atoms are easily excited by the incoming radiation. These excited atoms emit visible light when they return to their ground state. Common materials used as scintillators are crystals of sodium iodide and certain plastics. If such a material is attached to one end of a photomultiplier tube the photons emitted by the scintillator can be converted to an electric signal. This pulse can, in turn, be sent to an electronic counter. The scintillator device is much more sensitive than the Geiger Counter, mainly because of the higher density of the detecting medium.
Products & Services
Radiation Detectors
Radiation detectors are used for medical diagnoses, radioactive dating measurements, and measurements of background radiation, activity levels and radiation doses.
Chucks
Chucks are attachments used to hold a workpiece or cutting tool on a machine tool. This product area covers a variety of chuck types, including: core, diaphragm, draw bar, electrostatic, gear, grinding, lathe, milling, pull down, roll, safety, scroll, universal, and vacuum chucks.
Chuck Jaws
Chuck jaws are inserts that fit into a chuck and grip the workpiece. There are three types of chuck jaws: base jaws, hard jaws, and soft jaws.
Tool Holders
Tool holders (toolholders) are the physical interface between tooling and the machine tool. They vary in terms of machine-mount styles and are designed to perform specific applications.
Vises
Vises are used for work holding and during inspection, assembly, forming, welding, and machining operations. They usually consist of a screw, level, or cam-type mechanism that closes and holds two or more jaws around a workpiece
