Kicker pulsers for recycler NOVA upgrades

TL;DR

This paper details the development and improvements of a fast-rise-time thyratron pulser for the Recycler injection kicker system, achieving specified timing and field flatness requirements.

Contribution

It introduces a series of enhancements to the thyratron pulser, optimizing trigger, reservoir, and load impedance to meet stringent timing specifications.

Findings

Achieved rise time of less than 57 ns

Optimized trigger and reservoir settings for better performance

Enhanced load impedance handling for consistent operation

Abstract

An upgrade of the Recycler injection kicker system required a faster rise time pulser. This system required a field rise and fall time of < 57 ns and a field flattop of 1.6 {\mu}s. This paper describes the variety of improvements made over the years that have resulted in this latest thyratron pulser. The effects of the trigger, the reservoir and the load impedance on delay and rise time will be discussed.
