Total ionization cross section of cyclic organic molecules.

Two independent methods, namely, Binary-encounter Bethe (BEB) and complex scattering potential-ionization contribution (CSP-ic) methods, are employed to calculate the total ionization cross section (Q) for cyclic organic molecules from ionization threshold to 5 keV for which there is a paucity of data in the literature. The Q calculated with the (BEB/ωB97X) combination is found to give good agreement with the experimental results, the CSP-ic method, and the Q calculated from Irikura orbital energies. The Q for most of the targets are calculated for the first time over such a wide energy range.

Honeycomblike large area LaB6 plasma source for Multi-Purpose Plasma facility.

A Multi-Purpose Plasma (MP(2)) facility has been renovated from Hanbit mirror device [Kwon et al., Nucl. Fusion 43, 686 (2003)] by adopting the same philosophy of diversified plasma simulator (DiPS) [Chung et al.
