Rugged NaI(Tl) Crystals for Well Logging

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. 

Sodium Iodide crystals doped with Thallium (or NaI(Tl) crystals) have a very high scintillation or luminescence efficiency and a good energy resolution, NaI(Tl) scintillators have the largest light-out and an emission range well matched to photomultipliers with bialkali photocathodes at high efficiency, and combination with its easy availability of variety size and geometries and low cost, NaI(Tl) scintillators has become most widely used scintillators. NaI(Tl) crystals are a highly hygroscopic material, they must be put in a hermetical sealing housing in use.

Well-logging is done in harsh environments of high temperature, high pressure, and high humidity, the energy spectrum of Gamma rays needed to be measured in well-logging. Hangzhou Shalom EO selects high-quality temperature resist NaI(Tl) crystals as the scintillators, uses Titanium alloy as housing and Sapphire as optical windows to make the rugged well-logging NaI(Tl) scintillators, and combines with anti-shock and vibration design, our encapsulated well-logging NaI(Tl) crystals has a good reflects from well-logging equipment customers.
