Abstract
We measured the response of BAS-TR imaging plate (IP) to energetic aluminum ions up to 222 MeV, and compared it with predictions from a Monte Carlo simulation code using two different IP response models. Energetic aluminum ions were produced with an intense laser pulse, and the response was evaluated from cross-calibration between CR-39 track detector and IP energy spectrometer. For the first time, we obtained the response function of the BAS-TR IP for aluminum ions with a kinetic energy as high as 222 MeV. On close examination of the two IP response models, we confirm that the exponential model fits our experimental data better. Moreover, we find that the IP sensitivity in the exponential model is nearly constant in this energy range, suggesting that the response function can be determined even with little experimental data.
Highlights
An imaging plate (IP) is a film-like image sensor that records the incident radiation flux on a thin sheet called a phosphor layer
We find that the IP sensitivity remains nearly constant for all the incident Al ion energy in the exponential model, which suggests that the IP response function can be calculated for the entire energy range of the ion beams using just a few experimental data points
We measured the response of Biological Analysis System (BAS)-TR IP to Al ions up to 222 MeV
Summary
An imaging plate (IP) is a film-like image sensor that records the incident radiation flux on a thin sheet called a phosphor layer. 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]. Biological Analysis System (BAS) IP types are commonly used [8]. BAS-MS, SR, and TR IPs were primarily designed for high sensitivity, high resolution, and detection of beta particles from tritium, respectively [9,10]
