Abstract:

Experimental results are reported which show that the backward directed and unusable ion current in a reflex triode can be almost completely suppressed by adding a second anode, made of aluminized mylar, 0.5 cm from the existing polyethylene anode. Proton generation efficiencies in excess of 50 have been obtained. Author
