Abstract

We investigated the performance of a flight model of the position-sensitive tissue-equivalent proportional chamber (PS-TEPC) by irradiating with heavy-ion beams prior to launch to the International Space Station. The flight model operated stably with an effective gas gain of 1000 under a sealed gas. This gain was almost consistent with the effective gas gain under a gas flow. Energies of H, C, Si and Fe beams measured using the PS-TEPC flight model agreed well with calculations using the SRIM2008 code. Energy resolutions of 9.7% and 3.8% were obtained for the C and Fe beams, respectively. The uncertainties in dose equivalents were estimated to be better than 30% assuming both the theoretical model and best-fit function of linear energy transfer and referring to previously reported integrated dose fractions for an actual spacecraft. These features of the flight model satisfy the National Council on Radiation Protection and Measurements criteria for space dosimeters.

Abstract

［Abstract］ In order to confirm the plasma processing effect at a required point by visual observation, the plasma-chemical indicator (PCI) was fabricated. PCI is the piece of PET (polyethylene terephthalate) sheet strip on which a color indication mark which is sensitive and distinguishable to H_2O_2 and O_2, plasma was printed. The distinguishable property on PCI between H_2O_2, andO_2 plasma was realized by mixing two different colorants: red azo-dye and green phthalocyanine pigment were mixed into nitro cellulose resin. When PCI is treated by H_2O_2 and H_2O plasma, the color is continuously shifted from the purple of control PCI toward dull light green and light bluish green respectively after 15 minutes of treatment time. However, when the PCI is treated by O_2 plasma, it also continuously shifted toward a pinkish color after 15 minutes of treatment time. Therefore, it could be said that this prepared PCI is sensitive and distinguishable to H_2O_2 and O_2 plasma. Finally it is discovered that not only final color, but also the color in the middle of the change can also be available as PCI., [再録元]Journal of Photopolymer Science and Technology Volume25,Nember4(2012)539-544 (C) 2012CPST
