Due to their generally low eruptive melt viscosities and concomitant high diffusivities of volatiles, basaltic magmas degas relatively efficiently. This relative efficiency, combined with variations in style, extent, timing length scales degassing govern the range styles observed at volcanoes. The result is a surprising complexity regimes products volcanism. In particular, transition between cl...

To date, KEK has developed cleaning techniques for superconducting niobium RF cavities. These include: electro-polishing (EP), buffered chemical polishing (BCP) barrel polishing (BP), high pressure rinsing (HPR), megasonic ]lot water rinsing, degassing water, ozonated water cleaning, waste water treatment, and so oil. In this paper, we present findings from electro-poloishing of cavities, which...
