Abstract
Imaging plates are widely used in laser-plasma interaction experiments for detection of electrons, x-ray, gamma-ray, ions, and neutrons, therefore, the calibration of imaging plates to different types of ionizing and non-ionizing radiation is vital. In this paper, a universal response function of FUJI BAS-TR imaging plate is presented using experiment and Monte-Carlo simulation with respect to high-energy photons and ions. The sensitivity of imaging plate sensitivity to x-ray radiation was examined using radioactive Co-60 isotope. Furthermore, the fading and decay mechanism affected by phosphor stimulated process were also investigated by employing the high energy gamma-rays produced in laser-plasma experiment. Finally, an ion spectrometer was designed to examine the IP response to different ion energies during a laser-driven plasma experiment. The universal relation given, can be used to evaluate the response of the imaging plate against any other types of radiation.
