The LCLS-II project requires a beam spreader to distribute the 929 kHz electron beam between two undulators and a dump. Three kicker sections and a septum are required to divert beam for each undulator. When the kickers are not pulsed, beam proceeds to the dump. Each kicker magnet is approximately one meter in length and composed of multiple sections. Each section consists of a ferrite and...
The SNS High Voltage Converter Modulators power 92 klystrons at up to 135 kV and 120 A at pulse widths of up to 1.35 ms and 60 Hz to accelerate the H- beam through the linac to 1 GeV. Until recently, pulse droop was tolerated since the low-level RF system has sufficient control margin to compensate. However, with pending upgrades to the accelerator complex and concerns over elevated voltage...
The U.S. Naval Research Laboratory (NRL) has designed, constructed, and tested a twelve-bank system designed to be powered exclusively through Li-ion batteries and discharged into a water-based resistive load. An NRL-designed rapid capacitor charger is used to modulate the ≈630 V open-circuit voltage on the battery bank to charge the capacitor to a maximum value of 5 kV. The charger uses a...
In this contribution we present our findings on efficient ozone generation for environmental applications using a flexible solid-state Marx generator with a DBD plasma reactor. The flexibility of the Marx generator allows for a parametric study over various parameters, such as voltage amplitude, pulse duration, pulse repetition rate and repeated bursts of pulses. We measured ozone...
Sandia National Laboratories is researching an inertial confinement fusion concept named MagLIF [1] – Magnetized Liner Inertial Fusion. MagLIF utilizes Sandia’s Z Machine to radially compress a small cylindrical volume of pre-magnetized and laser-preheated deuterium fuel. These initial conditions appreciably relax the radial convergence requirements to realize fusion-relevant fuel conditions...
