Encapsulated NaI(Tl) Scintillators

  • The usual type of NaI(Tl) scintillator is a g ray detector whose NaI(Tl) crystal is cut into a cylinder and encapsulated in aluminum cases with an optical windows on the top.  For measurements, the radiation would enter from bottom or side face of the cylinder, and flurescence light output can be obtained from the optical window on the top, an uniform light output and the excellent energy resolution could be obtain for this type of design, and this type of the NaI(Tl) scintillators are widely used for in scintillation measurement or scintillation spectrometer detector for ordinary g ray.  Hangzhou Shalom EO supplies the standard size of the cylindrical NaI(Tl) scintillators in stock with fast delivery, and we also provide the customized size of cylindrical NaI(Tl) scintillators upon customer's request.
  • HIgh temperature type NaI(Tl) scintillators is a kind of high demanding scintillators with high temperature resistance, vibration resistance and shock resistance design, and the most high quality NaI(Tl) crystals are selected to be used in this type of the scintillators, it is widely used in the well-logging applications, under the harsh environment of high-temperature, high pressure and high humidity, to measure the energy spectrum of Gamma ray. They are suitable for Measurement While Drilling(MWD), the operating temperature range is optinal at: 20℃~100℃, -20℃~150℃ and -20℃~175℃.
  • The well type NaI(Tl) scintillator is a g ray detector with a cylindrical part (well) that is set concentrically in a cylindrical NaI(Tl) crystal. This assembly is often encapsulated in an aluminium housing.  For measurements, specimen is entered to well part and light output can be obtained from the optical window on the top.  This well shaped design is especially useful when low-level radiation must be efficiently detected. Hangzhou Shalom EO offers the customized well type NaI(Tl) scintillators upon customer's request.
  • The side-hole type NaI(Tl) scintillator is a detector with a side-hole passing vertically through the axis of the cylindrical NaI(Tl) crystal. It is usually encapsulated in aluminum housing. The measured specimen is passed through the side hole, and light output can be obtained from an optical window mounted on one or both sides of the end surfaces.  Hangzhou Shalom EO offers the customerized side-hole type NaI(Tl) scintillators upon customer's request. 
  • The NaI(Tl) crystal is cut into thin disk and housed in a aluminum ring, beryllium or aluminum foil is used as the entrance window, and it is used for measuring soft X-rays at low energy levels.suitable for soft X-ray and low energy γ-ray detection.Hangzhou Shalom EO supplies the customized thin NaI(Tl) scintillators upon customer's request.
