Electron emission from inconel under ion bombardment.

Abstract

In this work we have measured IEE yields y (defined as the average number of electrons ejected per incident ion) for 1.5-40 keV ions bombarding Inconel targets at norm al incidence. The choice of this alloy for our present study was based on the importance which Inconel has being the first-wall material of the JET (Joint European Torus). Our measurements were performed in UHV for two different surface conditions obtained after bombardment with 1017H2 ions/cm 2 at 20 keV or with 5 x 1017 A r+ ions/cm 2 at 30 keV.
