“…Considering the advantage of neutron angular distribution with the 9 Be(d, n) 10 B reaction for the measured deuteron energies [45][46][47] , an off-axis wing-shaped polyethylene pre-moderator was attached to the catcher, producing a thermal peak at room temperature. Additionally, in the future, a combination of reflectors will be employed to enhance the pre-moderated flux further.…”

The scientific and technical advances continue to support novel discoveries by allowing scientists to acquire new insights into the structure and properties of matter using new tools and sources. Notably, neutrons are among the most valuable sources in providing such a capability. At the Institute of Laser Engineering, Osaka, the first steps are taken towards the development of a table-top laser-driven neutron source, capable of producing a wide range of energies with high brightness and temporal resolution. By employing a pure hydrogen moderator, maintained at cryogenic temperature, a cold neutron ($$\le 25\hbox { meV}$$ ≤ 25 meV ) flux of $$\sim 2\times 10^3\hbox { n/cm}^2$$ ∼ 2 × 10 3 n/cm 2 /pulse was measured at the proximity of the moderator exit surface. The beam duration of hundreds of ns to tens of $$\upmu \hbox {s}$$ μ s is evaluated for neutron energies ranging from 100s keV down to meV via Monte-Carlo techniques. Presently, with the upcoming J-EPoCH high repetition rate laser at Osaka University, a cold neutron flux in orders of $$\sim 1\times 10^{9}\hbox { n/cm}^2/\hbox {s}$$ ∼ 1 × 10 9 n/cm 2 / s is expected to be delivered at the moderator in a compact beamline.

“…The total amount of accumulated charge was calculated using the beam current and the irradiation time. This value, which determines the neutron yield, is estimated to be 2 × 10 9 n/µC with a deuteron energy of 3 MeV [29]. This is an experimental value, and the test's condition is not the same as previous studies.…”

We developed a novel design of a Micro Pixel Chamber (µ-PIC) with resistive electrodes for a charged-particle-tracking detector in high-rate applications. Diamond-Like Carbon (DLC) thin film is used for the cathodes. The resistivity can be controlled flexibly (10 5−7 kΩ/sq.) at high uniformity. The fabrication-process was greatly improved and the resistive µ-PIC could be operated at 10×10 cm 2 . Resistors for the HV bias and capacitors for the AC coupling were completely removed by applying PCB and carbonsputtering techniques, and the resistive µ-PIC became a very compact detector. The performances of our new resistive µ-PIC were measured in various ways. Consequently, it was possible to attain high gas gains (> 10 4 ), high detection efficiency, and position resolution exceeding 100 µm. The spark current was suppressed, and the new resistive µ-PIC was operated stably under fast-neutrons irradiation. These features offer solutions for a chargedparticle-tracking detector in future high-rate applications.
