The X-ray irradiator developed by Freiberg Instruments is a standalone quantitative irradiation device that can be used in conjunction with photoluminescence/thermoluminescence dating devices (such as Lexsyg), paramagnetic dating devices (such as Magnettech desktop devices), or other experiments that require irradiation, such as food irradiation, irradiation sterilization, etc. Silicon photodiodes provide real-time monitoring of X-ray irradiators, designed for small sample irradiation or dosimeters used in dosimetry dating and other dosimetry applications.
Characteristics of X-ray Dose
1)Portable and easy-to-use design
2)Automatic tilt to ensure durability of X-ray tube
3)Accurately defined sample irradiation
4)Real time monitoring of X-ray flux
5)Just change the current (0.1-1.0 mA) to linearly change the dose rate tenfold.
6)Hardened filters (such as Al) can be easily replaced
7)Compatible with ESR quartz tubes (?=3-6 mm, 135 mm long), culture dishes, and sample cups/plates
8)Interface with MS 5000 ESR spectrometer and Lexsyg TL/OSL reader, allowing unlimited irradiation and measurement cycles

Al2O3: C responds to photoluminescence signals (1st) with different voltage settings and doses.
The linear signal response shows the reproducibility of X-ray dose delivery at different dose rates (high voltage, kV) settings.

Excellent stability
The temperature stability of the X-ray device ensures long-term stability and a constant dose rate.
