Absolute calibration of imaging plate detectors for electron kinetic energies between 150 keV and 1.75 MeV

Abstract

This paper presents the calibration of two different kinds of image plates (IPs) for detecting electrons with kinetic energy in the range of 150 keV-1.75 MeV. The calibration was performed using a Sr β source. The paper also provides the measured fading response for the IPs in the time range from 12 min to 18 h. Calibration results are compared to Monte Carlo simulations of energy deposited by the electrons in the sensitive layer of the IPs. It was found that within this energy range a linear relation between simulated energy deposited by the electron in the phosphor layer and the measured photo stimulated luminescence in the IP is adequate to model the response of the IP.

“…This method provides a possibility to obtain in a single shot two frames with data containing information on both plasma density and the magnetic field distribution. Additional data was provided by the X-ray K α imaging 12 , electron spectrometer 13 , ion grid collectors 14 , current probe 15 , and a 4-frame X-ray pinhole camera 16 .…”

Monte Carlo Study of Imaging Plate Response to Laser-Driven Aluminum Ion Beams

“…Since IPs were developed by Fuji film Co. in the early 1980s, they have been widely used in nuclear science and in medicine. While an IP is a passive detector and cannot be used in high repetition rate experiments, IPs have several advantages over other particle detectors: (1) immunity to electromagnetic pulse (EMP), (2) high dynamic range (4-5 orders of magnitude), (3) high spatial resolution (resolving to as low as 10 µm), and (4) reusability (signals of IPs can be erased with white light) [1,[5][6][7]. For radiation detection, Biological Analysis System (BAS) IP types are commonly used [8].…”

“…For ions, the spectral response function of an IP is measured in units of PSL per incident ion of a given energy. This must be done for each type of radiation and IP and scanner combination, because each combination has in general different responses [5,7,[13][14][15][16].…”

“…Researchers have measured the response of IPs to various radiation types such as electrons [5,7,13,[17][18][19][20][21], protons [12,14,[22][23][24], and X-ray [16,25] for a wide energy range. The measurement of IP responses to energetic heavy ion beams, however, is more challenging because it is difficult to produce heavy ion beams with sufficient particle fluence for IP calibration at a range of energies in a reasonably short time.…”

“…Recently, Rabhi et al reported on the responses of BAS-MS, SR, and TR for 1-200 MeV protons [12] and for 40-180 MeV electrons [21] using Geant4. Singh et al used FLUKA to calibrate the responses of BAS-MS and SR to 150 keV-1.75 MeV electrons [5].…”
