Sensitivity of charged particle activation analysis for long-lived radioactive nuclide determination

Oshima, Masumi*; Yamaguchi, Yurie*; Asai, Masato; Tsukada, Kazuaki; Goto, Jun*; Bamba, Shigeru*; Bi, C.*; Morimoto, Takao*

Journal of Nuclear Science and Technology, 56(9-10), p.866 - 872, 2019/09

Sensitivity of charged particle activation analysis with 8 MeV proton beam was studied for determination of 35 long-lived radioactive nuclides. Reaction cross sections for those nuclides were estimated with ALICE-91 code and isomer yield ratios were estimated from those of neighboring isotopes by taking into account their spins and parities. It was found that the proposed charged particle activation analysis should show high sensitivity for the determination of several hardly measurable nuclides with long half-lives such as $$^{135}$$Cs, $$^{244}$$Pu, $$^{129}$$I, $$^{126}$$Sn, $$^{93}$$Mo, $$^{107}$$Pd, $$^{236}$$U, $$^{248}$$Cm, and $$^{237}$$Np.

In a fusion reactor development, double-differential charged-particle emission cross sections(DDXc) are necessary to estimate nuclear heating and material damages of candidate materials irradiated with neutrons. Especially in light nuclei such as Be, Li, and C, nuclear reactions are complicated and difficult to estimate energy spectra of emitted particles based only on theoretical calculations Therefore development of a new technique for precise measurements of DDXc is quite important. Recently we successfully developed a new spectrometer for measurement of DDXc using a pencil-beam DT neutron source of FNS in JAERI. In the present study we carried out measurements of DDXc of $$^{9}$$Be, $$^{12}$$C, $$^{19}$$F, and $$^{27}$$Al using the spectrometer. The present technique was valid from the result of measurement for the $$^{27}$$Al(n,x$$alpha$$) reactions. Slight differences appeared between measured data and evaluation or previous experimental values for $$^{9}$$Be(n,x$$alpha$$) reactions at backward scattering angle and in lower energy region.

Radiation resistivity of polymeric materials with data tables

Center for Proton Accelerator Facilities Planning group

JAERI-Data/Code 2003-015, 255 Pages, 2003/09

JAERI-Data-Code-2003-015.pdf:8.14MB

This document presents radiation resistivity of various polymeric materials with collected data tables that are the candidate materials to be used in the High Intensity Proton Accelerator Facility Project, J-PARC, which is to produce MW-class high power proton beams. The effect of radiation damage and deterioration by loss-beam or secondary particle beam influences the performance and the reliability of various instruments. The radiation damage consists of mechanical property, electrical property and gas-evolution property, and these properties depend entirely upon the kind of radiation, energy and dose intensity. The first part of this document methodically introduces the general feature of polymer and its radiation-induced deterioration mechanisms, and the second part of the document shows the compiled data for irradiation effects of polymeric materials. The sources of the data are the published reports from the worldwide references.

Present status and future subjects of the analytical studies related with application of charged particles and RI to materials science and biotechnology

Working Group in the Advisory Committee of the Analytical Studies for Application of Charged Particl

JAERI-Review 2003-008, 42 Pages, 2003/03

JAERI-Review-2003-008.pdf:3.12MB

The position in the research field of radiation application of "Theoretical Analysis Group for Radiation Application" which will be set up within fiscal 2003, and the relation between the research that this analytical group will advance in future and the analytical research made so far at JAERI Takasaki are summarized. First, the theoretical analysis group for radiation application extracts only the core element from the analysis of reactive process of charged particles in the materials and from the irradiation effect, and then constructs the simplified model. Second, the validity of the constructed model is verified by advancing the theoretical analysis based on the model, and the calculated result is fed back to the experiment, and then the verification is carried out. Finally, the general-purpose theorization will be conducted by generalizing and universalizing the obtained model concerning the specific system. The obtained outcomes will be applied to other systems, and, will consequently, contribute to the promotion of new technological development.
