The Aurora Prompt Gamma Flash Simulator has been undergoing a series of machine upgrades in response to recent simulation requirements. One outgrowth of these new requirements is the need for improved synchronization of the four Blumlein modules. Physics International and Sandia National Laboratories have developed and tested an innovative oil-switch trigger scheme consisting of a charged transmission line pulse generator switched by a 3-MV, electrically-triggered, Rimfire gas switch. Recently, we have tested the oil switch trigger pulser on one of the 12-MV, Blumlein oil switches. In these tests, we have achieved shot-to-shot jitter of 5 ns. By comparison, jitter of the present trigger scheme has been measured to be 10 ns. In this paper, we will discuss the jitter-reduction techniques, the design of the low-jitter, oil switch trigger pulser, and the tests results achieved on Aurora. 9 refs., 9 figs., 3 tabs.
