What are scintillation crystals?
Scintillation crystals are used in detectors to convert X-rays or gamma rays into light pulses that are subsequently detected by either a Photomultiplier Tube (PMT) or a Silicon Photomultiplier (SiPM). …
How do scintillation crystals work?
How do they work? Scintillators are a group of materials that luminesce when exposed to ionizing radiation. In layman’s terms that means these materials emit light when they absorb particles or electromagnetic waves that create “free” electrons in the material.
What material is used in scintillation crystal?
NaI(Tl) Sodium Iodide Sodium Iodide crystals are the most widely available scintillation detector today. It has a variety of uses from Isotopic identification to medical gamma cameras. Good light yield, combined with an emission wavelength that matches up well with PMTs, makes NaI(TL) ideal for many applications.
What are the scintillating materials?
What Are Scintillation Materials? Scintillators are materials that absorb energetic radiation such as gamma rays, X-rays, or neutrons and convert that energy into short bursts of visible photons. These photons are then converted into electrical pulses by photo-detectors.
What is a scintillation crystal and photomultiplier in CT detector and describe it?
A scintillation detector consists of a crystal or other phosphor coupled with its mount to a PM tube with a silicone oil light-couple. The oil light-couple is necessary to obtain an intimate connection of the phosphor with the photomultiplier to ensure the efficient passage of very small light photons.
What do scintillators do?
Scintillators are materials that are able to convert high energy radiation such as X or gamma-rays to a near visible or visible light. They are widely used as detectors in medical diagnostics, high energy physics and geophysical exploration (ref. Knoll).
Why are scintillators used?
What does a scintillation detector do?
Scintillation detectors are used for the determination of the high-energy part of the X-ray spectrum. In scintillation detectors the material of the detector is excited to luminescence (emission of visible or near-visible light photons) by the absorbed photons or particles.

What are the different sizes of scintillating crystals?
The scintillating core contains a combination of fluorescent dopants selected to produce the desired scintillation, optical and radiation-resistance characteristics. Current sizes range from 0.5 mm to 3 mm round cross-sections and are available in canes, spools, ribbons, and arrays. Custom sizes and designs available upon request.
What kind of material is a scintillator?
Scintillator – a special material that converts particle energy (e.g. the energy in a gamma ray or any source of ionizing radiation) into visible light. Offering a wide variety of scintillator crystal materials and continuing to develop new scintillators to meet current and future market needs.
Which is the best Crystal for a scintillation detector?
Sodium Iodide crystals are the most widely available scintillation detector today. It has a variety of uses from Isotopic identification to medical gamma cameras. Good light yield, combined with an emission wavelength that matches up well with PMTs, makes NaI (TL) ideal for many applications.
