• Automation of etch pit analyses on solid-state nuclear track detectors with machine learning for laser-driven ion acceleration

  Solid-state nuclear track detectors (SSNTDs) are often used as ion detectors in laser-driven ion acceleration experiments and are considered to be the most reliable ion diagnostics since they are sensitive only to ions and measure ions one by one. However, ion pit analyses require tremendous time and effort in chemical etching, microscope scanning, and ion pit identification by eyes. From a laser-driven ion acceleration experiment, there are typically millions of microscopic images, and it is practically impossible to analyze all of them by hand. This research aims to improve the efficiency and automation of SSNTD analyses for laser-driven ion acceleration. We use two sets of data obtained from calibration experiments with a conventional accelerator where ions with known nuclides and energies are generated and from actual laser experiments using SSNTDs. After chemical etching and scanning the SSNTDs with an optical microscope, we use machine learning to distinguish the ion etch pits from noises. From the results of the calibration experiment, we confirm highly accurate etch-pit detection with machine learning. We are also able to detect etch pits with machine learning from the laser-driven ion acceleration experiment, which is much noisier than calibration experiments. By using machine learning, we successfully identify ion etch pits ∼105 from more than 10 000 microscopic images with a precision of ≳95%. A million microscopic images can be examined with a recent entry-level computer within a day with high precision. Machine learning tremendously reduces the time consumption on ion etch pit analyses detected on SSNTDs.

• The Role of Collision Ionization of K-Shell Ions in Nonequilibrium Plasmas Produced by the Action of Super Strong, Ultrashort PW-Class Laser Pulses on Micron-Scale Argon Clusters with Intensity up to 5 × 1021 W/cm2

  The generation of highly charged ions in laser plasmas is usually associated with collisional ionization processes that occur in electron–ion collisions. An alternative ionization channel caused by tunnel ionization in an optical field is also capable of effectively producing highly charged ions with ionization potentials of several kiloelectronvolts when the laser intensity q > 1020 W/cm2. It is challenging to clearly distinguish the impacts of the optical field and collisional ionizations on the evolution of the charge state of a nonequilibrium plasma produced by the interaction of high-intensity, ultrashort PW-class laser pulses with dense matter. In the present work, it is shown that the answer to this question can be obtained in some cases by observing the X-ray spectral lines caused by the transition of an electron into the K-shell of highly charged ions. The time-dependent calculations of plasma kinetics show that this is possible, for example, if sufficiently small clusters targets with low-density background gas are irradiated. In the case of Ar plasma, the limit of the cluster radius was estimated to be R0 = 0.1 μm. The calculation results for argon ions were compared with the results of the experiment at the J-KAREN-P laser facility at QST-KPSI.

• Measurement method for laser-accelerated multi-hundred-MeV protons utilizing multiple Coulomb scattering in an emulsion cloud chamber

  Takafumi Asai, Chihiro Inoue, Satoshi Jinno, Nobuko Kitagawa, Satoshi Kodaira, Kunihiro Morishima, Yuji Fukuda, Tomoya Yamauchi, Masato Kanasaki

  Abstract We have developed a measurement method for laser-accelerated multi-hundred-MeV-class protons using an emulsion cloud chamber (ECC), which consists of a stack of nuclear emulsion films and scatterer plates. Based on multiple Coulomb scattering (MCS) theory depending on the incident energy of protons, we have constructed a regression model to inversely estimate the incident energy by means of support vector regression (SVR) with a radial basis function. The prediction accuracy was approximately 10% (standard deviation) for protons with energies up to 0.3 GeV in a 25 layer ECC with 0.5 mm thick tungsten plates, corresponding to a 2 cm thick compact detector.

• Mass-resolved ion measurement by particle counting analysis for characterizing relativistic ion beams driven by lasers

  Particle counting analysis is a possible way to characterize GeV-scale, multi-species ions produced in laser-driven experiments. We present a multi-layered scintillation detector to differentiate multi-species ions of different masses and energies. The proposed detector concept offers potential advantages over conventional diagnostics in terms of (1) high sensitivity to GeV ions, (2) realtime analysis, and (3) the ability to differentiate ions with the same charge-to-mass ratio. A novel choice of multiple scintillators with different ion stopping powers results in a significant difference in energy deposition between the scintillators, allowing accurate particle identification in the GeV range. Here, we report a successful demonstration of particle identification for heavy ions, performed at the Heavy Ion Medical Accelerator in Chiba. In the experiment, the proposed detector setup showed the ability to differentiate particles with similar atomic numbers, such as C⁶⁺ and O⁸⁺ ions, and provided an excellent energy resolution of 0.41%–1.2% (including relativistic effect, 0.51%--1.6%).

• Laser-driven multi-MeV high-purity proton acceleration via anisotropic ambipolar expansion of micron-scale hydrogen clusters.

  Multi-MeV high-purity proton acceleration by using a hydrogen cluster target irradiated with repetitive, relativistic intensity laser pulses has been demonstrated. Statistical analysis of hundreds of data sets highlights the existence of markedly high energy protons produced from the laser-irradiated clusters with micron-scale diameters. The spatial distribution of the accelerated protons is found to be anisotropic, where the higher energy protons are preferentially accelerated along the laser propagation direction due to the relativistic effect. These features are supported by three-dimensional (3D) particle-in-cell (PIC) simulations, which show that directional, higher energy protons are generated via the anisotropic ambipolar expansion of the micron-scale clusters. The number of protons accelerating along the laser propagation direction is found to be as high as 1.6 [Formula: see text] [Formula: see text] 10[Formula: see text]/MeV/sr/shot with an energy of 2.8 [Formula: see text] MeV, indicating that laser-driven proton acceleration using the micron-scale hydrogen clusters is promising as a compact, repetitive, multi-MeV high-purity proton source for various applications.

• Sudden increase of the radiation chemical yield for loss of carbonate ester in PADC detector where the track overlapping of 28 MeV electrons becomes significant

  Tamon KUSUMOTO, Yutaka MORI, Masato KANASAKI, Keiji ODA, Satoshi KODAIRA, Yoshihide HONDA, Sachiko TOJO, Rémi BARILLON, YAMAUCHI TOMOYA

  The latent track structure of 28 MeV electrons in poly(allyl diglycol carbonate), PADC, has been investigated using FT-IR spectral method. The density of ether decreases linearly with increasing the fluence. Chemical damage parameters of effective track radius, damage density and radiation chemical yield, for loss of ether are evaluated as 0.023 nm, 0.01 scissions/nm and 19 sci

  固体飛跡検出器として用いられているCR-39は,光学材料として開発されたプラスチック素材で,大気中のラドン濃度計測や,宇宙線計測,生物細胞照射実験など様々な分野に利用されている.レーザープラズマのような電子線やX線が混在する場においても,イオンのみを選択的に検出し,またその精度が非常に高いことから,混成場におけるイオン検出器として注目を集めている.CR-39には,イオンビーム特性(エネルギー同定,核種同定など)に関する情報を引き出すために,様々な検出法や解析手法が存在する.しかし,それら手法のほとんどは,プラズマ研究者に広く知られていないのが現状である.本解説では,ここ数年間の日本原子力研究開発機構と神戸大学大学院海事科学研究科の共同研究の成果を中心に,CR-39を用いたレーザー駆動イオンビームの特性評価に関する解説を行う.

  27, Mar. 2013, Japanese, Kobe University, 高強度レーザーによる固体ターゲットを用いたレーザー駆動イオン加速実験では、最大で40 MeVのプロトンの発生が確認されている。イオン計測にはCR-39 が広く利用されているが、最大エネルギーの決定精度については、様々な問題点が残されていた。本研究では積層したCR-39 を用い、レーザーによって加速されたイオンの計測を行なった。エッチピットが確認された最終層のCR-39 に対して、多段階エッチング法を適用することで、最終層内での飛程を算出し、最大エネルギーをE=0.1 MeV という高い精度で決定した。また、ZnS(Ag)蛍光体を用いたオンライン型検出器による計測も行った。, Domestic conference
