Cadmium Tungstate Scintillator Array

Product Material: Cadmium Tungstate Crystal Atomic Number (Effective): 74
Application: High-energy X-ray Inspection Equipment,CT Scanner Equipment Advantage: High X-ray Stopping Power ,low Afterglow
Array Type: Liner And 2D Afterglow@30ms: 0.1-0.2%
Minimal Pixel Size: Liner:0.4mm ;2D:1mm Hygroscopic: No
High Light:

CWO cadmium tungstate scintillator


14000nm CWO Matrix


Liner 2D cadmium tungstate scintillator

High-energy X-ray inspection equipment CWO Matrix CWO scintillatior Array


CWO array with high X-ray stopping power is used especially in high-energy X-ray inspection equipment.

It is suitable for a CT scanner equipment due to its low afterglow property.

We can prepare various types of arrays.Large area 2D array can be used in the airport checked baggage inspection equipment (CT) for security application.

Mechanical design for assembling:


Based on the end use of assembled array, there are many kinds of mechanic design from Kinheng to meet the medical and security inspection industry.

1D Liner array are mainly used for Security inspection industy, such as Bagger scanner, Aviation scanner, 3D scanner and NDT. Material Including CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. They are typically coupled with Silicon Photodiode linear array for read out.

2D array are normally used for imaging, including Medical(SPECT, PET, PET-CT, ToF-PET), SEM, Gamma camera. These 2D array are typically coupled with SIPM array, PMT array for read out. Kinheng provide 2D array including LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator etc.

Below is kinheng’s typically design drawing for 1D And 2D array for industry.
