1.5" x 1.5" CsI(Tl) Gamma Scintillation Detector
These small 1.5" detectors are great for portable systems, small enough to handle yet big enough to produce a decent gamma spectrum.
Thallium doped Caesium Iodide or CsI(Tl) scintillation crystals are a great alternative to NaI(Tl) and have several advantages.
- Caesium Iodide is not hygroscopic allowing for the crystal to be coupled directly to the PMT
- Caesium iodide has a density of 4.51 gr/cm^3 and is almost 23% more efficient than NaI(Tl)
- Slightly less fragile
The detector is supplied with an SHV male connector, compatible with the GS-USB-PRO, but can be supplied with a HV-BNC if required.
We recommend this detector for use with the GS-PRO-V5 spectrometer.
This detector is built by Bee Research from quality new components.
