“…Proton acceleration up to energies of tens of MeV using high intensity laser pulses (I >10 18 W/cm 2 ) that interact with thin solid targets has been an issue of considerable interest over the last two decades, both experimentally and theoretically [1][2][3][4][5][6]. Most studies on laser-driven proton acceleration were performed under experimental conditions which are characteristic of the so-called Target Normal Sheath Acceleration (TNSA) mechanism.…”

“…The analysis of proton beams characteristics and of the associated energy distribution is usually performed with radiochromic films or solid-state nuclear track detectors, most often coupled with Thomson Parabola spectrometers [3,4]. The CR-39 nuclear track detector [polyallyl-diglycol-carbonate (PADC), C 12 H 18 O 7 ], has demonstrated its capabilities to detect protons as it is insensitive to electromagnetic noise [3,7,8], while showing high uniformity and high sensitivity to ions, as well as excellent etching properties. As reported in [3], once the laser accelerated protons are analyzed by means of CR-39 detectors, the output data can be used to characterize accelerated ion beams without requiring an additional spectrometer.…”

A high energy charged particle (for example a proton) travelling through a CR-39 detector loses energy along its trajectory in matter by electronic collisions, by scattering, then stops when it has completely deposed its energy into the detector material, according to the Bragg curve.…”

We show that a spectral distribution of laser-accelerated protons can be extracted by analyzing the proton track diameters observed on the front side of a second CR-39 detector arranged in a stack. The correspondence between the proton track diameter and the incident energy on the second detector is established by knowing that protons with energies only higher than 10.5 MeV can fully deposit their energy in the second CR-39 detector. The correlation between the laser-accelerated proton track diameters observed on the front side of the second CR-39 detector and the proton incident energy on the detector stack is also presented. By calculating the proton number stopped in the CR-39 stack, we find out that its dependence on the proton energy in the 1–15 MeV range presents some discontinuities at energies higher than 9 MeV. Thus, we build a calibration curve of the track diameter as a function of the proton incident energy within the 1–9 MeV range, and we infer the associated analytical function as the calculations performed indicate best results for proton spectra within the 1–9 MeV range. The calibration curve is used as a tool to ascertain the pits identified on the surfaces of both CR-39 detectors to proton tracks. The proton tracks spatial distribution analyzed by optical and atomic force microscopy is correlated with the peculiarity of the used targets.

Henna leaves are a pri or ity ma te rial for hair dyes and body tat toos and have been used for this pur pose for de cades. In Iraq, henna is used widely but it re quires sub stan tial con trols. Iraq is con sid ered an en vi ron men tally pol luted area as a re sult of the wars it has ex pe ri enced, hence, this study has been con ducted to cal cu late the level of 222 Rn con tam i na tion in henna leaves using a CR-39 nu clear track de tec tor. The leaves were col lected from the prov ince of Basrah, which is lo cated in south ern Iraq and is fa mous for cul ti va tion of this plant. The ra don concen tra tions were found to range from 12.140 to 16.255 Bqm-3 in Al-Faw, and from 7.613 to 11.111 Bqm-3 in Abu Al Khasib. Ra don ac tiv ity ranged from 6.09×10-4 to 8.16×10-4 Bq in Al-Faw, whereas, in Abu Al Khasib it ranged from 3.82×10-4 to 5.58×10-4 Bq. Ra don specific ac tiv ity ranged from 1.22×10-4 to 1.63×10-4 Bqg-1 in Al-Faw, and from 7.64×10-5 to 1.12×10-4 Bqg-1 in Abu Al Khasib. The ra don ex ha la tion rate ranged from 4.05×10-4 to 5.43×10-4 with an av er age of 4.69×10-4 Bqm-2 d-1 in Al-Faw, and from 2.54×10-4 to 3.71×10-4 with an av er age of 3.22×10-4 Bqm-2 d-1 in Abu Al Khasib. Af ter ob tain ing the re sults, one can con clude that the henna plant col lected from these ar eas is safe for hu man use and is free from high rates of 222 Rn.

“…CR39 nuclear track detectors also represent a very convenient tool for time-integrated measurements of charged particle fluences as well as for neutron dosimetry based on the detection of recoil protons [26][27][28]. The main advantages of these detectors are their high sensitivity for ions within certain energy ranges and their insensitivity to photons and electrons for reasonable dose.…”

ELI (Extreme Light Infrastructure) multidisciplinary applications of laser-ion acceleration (ELIMAIA) is one the user facilities beamlines of the ELI-Beamlines facility in Prague. It will be dedicated to the transport of laser-driven ion beams and equipped with detectors for diagnostics and dosimetry, in order to carry out experiments for a broad range of multidisciplinary applications. One of the aims of the beamline is also to demonstrate the feasibility of these peculiar beams for possible medical applications, which means delivering controllable and stable beams, properly monitoring their transport parameters and accurately measuring the dose per shot. To fulfil this task, innovative systems of charged particle beam diagnostics have been realized and alternative approaches for relative and absolute dosimetry have been proposed. Concerning the first one, real-time diagnostic solutions have been adopted, involving the use of time-of-flight techniques and Thomson parabola spectrometry for an on-line characterization of the ion beam parameters, as well as radiochromic films, nuclear track detectors (typically CR39), and image plates for single shot measurements. For beam dosimetry, real-time beam/dose monitoring detectors have been realized, like the secondary emission monitor and a double-gap ionization chamber, which can be cross calibrated against a Faraday cup, used for absolute dosimetry. The main features of these detectors are reported in this work together with a description of their working principle and some preliminary tests.
