Xray Dose for ESR

Benchtop X-ray irradiator for treating ESR samples

Versatile applications

The Xray Dose device is useful to simulate environmental impacts such as cosmic & terrestrial radiation, or industrial processes such as irradiation of food & pharmaceuticals.

Linear regression analysis of blue OSL dose response of a single α-Al2O3:C
(in 4 sets at different times after various down times) to irradiations using different
voltage settings. DAP-dose is the surface dose as measured by an ionisation
chamber in the beam.

 Features

  • Portable and easy-to-use design

  • Automated ramping to ensure durability of X-ray tube

  • Precisely defined sample irradiation

  • Real-time monitoring of X-ray flux

  • The dose rate can be linearly varied by a factor of ten by
    simply changing the current (0.1 – 1.0 mA)

  • Hardening filter (e.g. Al) can be changed easily

  • Compatibility with ESR quartz tubes (Ø = 3 – 6 mm,
    135 mm long), petri dish and sample cups/discs

  • Interface to MS 5000 ESR spectrometer and lexsyg TL/OSL
    reader, allows unlimited irradiation and measurement cycles

Easy Operation from touch screen

 

The Xray Dose can work individually, controlled by a touch screen.

  • individual adjustment of dose rate

  • time of irradiation may be chosen freely

  • display temperature, high voltage & current

 

Alternatively, it can be connected to the MS 5000 and controlled by ESRStudio.
