A physical model for anode deposition rates in parallel‐plate, dc‐diode sputtering is presented and tested. The deposition rate has been measured as a function of the discharge voltage, the anode–cathode gap and the pressure, using silicon or m

The role of highly vibrationally excited hydrogen molecules has been postulated to be of great importance in H− ion sources. However the the difficulty of making in situ measurements has led to a paucity of direct determinations of these species wi

Using vacuum ultraviolet laser‐absorption spectroscopy, the H° density and temperature are measured as a function of discharge current and H2‐gas flow in both the plasma column and the drift region between the plasma column and the emitter in th

A photocathode made from polycrystalline lanthanum hexaboride (LaB6) has produced nanosecond‐length electron pulses when excited by an excimer laser at 308 nm. Peak currents in excess of 1 A have been observed, with quantum yields of 4×10−5 bein

We recently reported the H0 density and temperature in the 4X source (a Penning SPS) as a function of the H2 gas flow and the discharge current, as well as a measurement of the H2 (v=1) vibrational state density. In this paper, we report the H0 densi
