Response functions of Fuji imaging plates to monoenergetic protons in the energy range 0.6–3.2 MeV

Abstract

We have measured the responses of Fuji MS, SR, and TR imaging plates (IPs) to protons with energies ranging from 0.6 to 3.2 MeV. Monoenergetic protons were produced with the 3.5 MV AIFIRA (Applications Interdisciplinaires de Faisceaux d'Ions en Région Aquitaine) accelerator at the Centre d'Etudes Nucléaires de Bordeaux Gradignan (CENBG). The IPs were irradiated with protons backscattered off a tantalum target. We present the photo-stimulated luminescence response of the IPs together with the fading measurements for these IPs. A method is applied to allow correction of fading effects for variable proton irradiation duration. Using the IP fading corrections, a model of the IP response function to protons was developed. The model enables extrapolation of the IP response to protons up to proton energies of 10 MeV. Our work is finally compared to previous works conducted on Fuji TR IP response to protons.

Everything SAXS: small-angle scattering pattern collection and correction

“…A decay time correction should therefore be considered for accurate reproduction of intensity, and such a correction is described amongst others by Hammersley et al [67]. It should be noted that this time decay is likely also dependent on the energy of the used x-rays as it is for protons [16].…”

Collimated fast electron beam generation in critical density plasma

“…The cut off energy, average energy and divergence angle are 5 MeV, 0.5 MeV, and 138 (FWHM), respectively. Assuming the conversion efficiency from laser to proton energy of 1% and using proton sensitivity for IP, 20,21 signal intensity on the IP from protons are 20 times smaller than that from electrons. 16 …”

“…IV) indicates also similar large divergence and the signal intensity on the IP from protons could be 20 times smaller than that from electrons. 16,20,21 Thus, the narrow divergence signal is due to fast electrons.…”

Two parameter model of Fuji imaging plate response function to protons

“…The composition of this layer can vary from one type of IP to the other and is detailed in Ref. 11. The following layer serves as support and the last layer is magnetized to facilitate handling.…”
