Risetime sharpening using magnetic insulation in the aurora diode

Abstract

Theoretical calculations indicate that Aurora diode geometrical reconfigurations that delay the onset of magnetic insulation should yield a decreased risetime. Experimentally these diode modifications have resulted in a decrease of the beam risetime from approximately 80 ns to 20 ns. * ne first portion Of this work was =med Out Corporation. Newington, VA.

(The initial spikes on the traces are fiducial markers.) This measured risetime (10 ns) was achieved by combining a "falsework" diode with drift tube nose erosion. See reference 9.
