At CERN, gas-filled ionization chambers PTW-34031 (PMI) are commonly used in radiation fields including neutrons, protons and $$gamma$$-rays. A response function for each particle is calculated by the radiation transport code FLUKA. To validate a response function to high energy neutrons, benchmark experiments with quasi mono-energetic neutrons have been carried out at RCNP, Osaka University. For neutron irradiation with energies below 200 MeV, very good agreement was found comparing the FLUKA simulations and the measurements. In addition it was found that at proton energies of 250 and 392 MeV, results calculated with neutron sources underestimate the experimental data due to a non-negligible gamma component originating from the target $$^{7}$$Li(p,n)Be reaction.

We have measured neutron energy spectra for the 80, 100 and 296 MeV proton incident reactions at the RCNP cyclotron facility using time-of-flight method. The neutron energy spectrum consisted of the peak and continuum parts and the peak intensity was 0.9-1.1 $$times$$ 10$$^{10}$$ neutrons/sr/$$mu$$C. The ratio of peak intensity of the spectrum to the total intensity was between 0.38 and 0.48. To consider the correction required to derive a response in the peak region from the measured total response for neutron monitors, we proposed the subtraction method using energy spectra between 0$$^{circ}$$ and 25$$^{circ}$$. The normalizing factor k against the 25$$^{circ}$$ neutron fluence that equalizes the 0$$^{circ}$$ neutron fluence in the continuum region was from 0.74 to 1.02. With our previous results, we have obtained data for characterization of monoenergetic neutron field for the $$^{7}$$Li(p,n) reaction with 80$$sim$$389 MeV protons at the RCNP cyclotron facility.

This topical review presents results from neutron inelastic scattering experiments on single crystals of UPd$$_2$$Al$$_3$$. We present a detailed and complete characterization of the wave vector- and energy-dependent magnetization dynamics in UPd$$_2$$Al$$_3$$ as measured by neutron inelastic scattering primarily in the form of extensive surveys in energy-momentum space under a wide range of experimental conditions, and put our observations in context with data that has been published previously by two independent groups. This study yields unique insight into the low-temperature ground state, which exhibits a microscopic coexistence of antiferromagnetism and superconductivity, makingUPd$$_2$$Al$$_3$$ one of the most accessible heavy-fermion superconductors that can be fully characterized by neutron spectroscopy.

Investigation on Cs penetration behavior into concrete using INAA

Yoneyama, Kai*; Sato, Isamu*; Hagura, Naoto*; Furuya, Noriaki*; Miwa, Shuhei; Suzuki, Eriko

no journal, , 

In order to clarify the Cs penetration behavior into concrete, the Cs penetration tests from low-concentration Cs solution into aggregate, mortar and concrete was carried out. The concentrations of penetrated Cs along the depth from surface were analyzed using INAA. At the depths deeper than 0.5 mm, the concentration of Cs in concrete was higher than the total concentration of Cs in aggregate and mortar. This result has been shown also in the previous penetration tests using more high-concentration Cs solution. These are considered to be occurred because interface of aggregates and mortar would promote the penetration of Cs.

no journal, , 

In order to develop an analysis technique of penetrated Cs into concrete, the concentration of penetrated Cs into bulk concretes and bulk mortars were quantitatively analyzed using PIXE. The results of concentration decrease along the depth from surface proved the applicability of PIXE to the quantitative analyses of low-concentration Cs in bulk samples. This can reduce experimental errors and contribute to a detailed estimation of Cs penetration behavior.

In order to develop an analysis technique of penetrated Cs into concrete, the concentration of penetrated Cs into bulk concretes and bulk mortars were quantitatively analyzed using PIXE. The difference of penetration depth between concretes and mortars, which has been observed also in the Cs penetration tests using more high-concentration Cs solutions, was observed. These results showed the applicability of PIXE to the quantitative analyses of low-concentration Cs in bulk samples.
