Single channel patch-clamp techniques were used to study nicotinic acetylcholine receptors in cultured rat myotubes. The single channel conductance in pure cesium and sodium levels off at high concentrations, as if a binding site within the channel were saturating . The conductances at very low concentrations, however, are larger than predicted by the simplest one-site transport model fitted to...

We study the excitation and ionization of cesium Rydberg states in an electric field ($\ensuremath{\approx}\phantom{\rule{0.16em}{0ex}}2200\phantom{\rule{4pt}{0ex}}\mathrm{V}/\mathrm{cm}$) near classical field-ionization threshold ($\ensuremath{\approx}\ensuremath{-}280\phantom{\rule{4pt}{0ex}}{\mathrm{cm}}^{\ensuremath{-}1}$ binding energy) by three-dimensional (3D) ion-electron coincidence sp...
In order to realize negative ion sources and accelerators to be applicable to International Thermonuclear Experimental Reactor and JT-60 Super Advanced, a large cesium (Cs)-seeded negative ion source and a multi-aperture and multi-stage electric acceleration have been developed at Japan Atomic Energy Agency (JAEA). Long pulse production and acceleration of the negative ion beams have been indep...
Results of studies on the secondary Ion mass spectrometry (SIMS) of CsI by Cs+ ion desorption ionization Fourier transform mass spectrometry (DI-FTMS) are reported. Owlng to the reiatlveiy long time scale of the FTMS experiment, the "anomalous cluster Ion intensity" for the Cs( CsI), + cluster ions observed by Campana is very dlstlnct. A second objective of this study was to evaluate the utilit...
