Study of radiation-induced primary process by ion pulse radiolysis

JAEA-Review 2005-001, TIARA Annual Report 2004, p.183 - 185, 2006/01

A heavy-ion-pulse radiolysis technology was developed using a single-photon-counting system. In the system, the ion beam was injected a thin scintillator before irradiating the sample. The light emitted from the scintillator by the ion irradiation was used as analyzing source to detect the absorption of primary species in water. Measurement of time-dependent absorption of hydrated electrons in water was achieved using the system, which demonstrates the usefulness of this technique.

Fabrication of nanowires using high-energy ion beams

Tsukuda, Satoshi*; Seki, Shuhei*; Tagawa, Seiichi*; Sugimoto, Masaki; Idesaki, Akira; Tanaka, Shigeru; Oshima, Akihiro*

Journal of Physical Chemistry B, 108(11), p.3407 - 3409, 2004/03

Nano-wire formation in Si-based polymer thin films using a heavy ion beam is discussed in terms of energy density deposition along ion tracks. Gelation of the polymer along the ion track results in cross-linking to produce nano-wires with size and number density controllable by selecting appropriate ion beam characteristics and polymer materials. Ion bombardment of polycarbosilane (PCS), PCS-polyvinylsilane blend polymer, and polymethylphenylsilane produces nano-wires with radii of 30 nm depending on the type of ion beam. The difference in size is shown to be related to the efficiency of the cross-linking reaction considering the deposited energy distribution along the ion tracks.
