New LDRD Projects for FY19
Engineering Atomically Controlled Complex Oxide/Aqueous Interfaces
Lead Scientist: Harold Hwang
This project seeks to establish a research platform for developing functional complex oxide/aqueous interfaces using atomic-scale controlled epitaxial heterostructures, in order to atomistically design their photoelectrochemical (PEC) properties. The goal is to establish a flexible experimental and theoretical platform on which to develop new materials systems, controlled on the atomic scale, to enhance the efficiency of hydrogen generation using water and sunlight.
Active Q-switching an X-ray Cavity to Enable a Regenerative Amplifier Free-Electron Laser at LCLS-II
Lead Scientist: Gabriel Marcus
This project focuses on demonstrating that an X-ray Bragg crystal in a relatively simple ringdown cavity can be actively Q-switched with a short-pulsed optical laser providing additional flexibility compared to the standard passive elements. The goal is to develop key enabling technologies to enhance the baseline LCLS-II performance by conducting targeted R&D on the optics needed for an FEL scale RAFEL cavity.
High-Throughput Real-Time Theory
Lead Scientist: Todd Martinez
See The Martinez Group for more research information.
Generation and Manipulation of High Pressure, Low Temperature Plasmas Using High-Power RF Pulse Modulation
Lead Scientist: Brandon Weatherford
This project investigates a new method of generating low temperature plasmas (LTPs) for plasma chemistry, up to atmospheric pressure, using fast-pulsed high power RF structures. The goals are to use SLAC's expertise in HPRF to address two fundamental challenges in LTPs: efficient generation of uniform discharges at high pressures - up to atmosphere, and control of electrion energy distributions using pusle shaping vs. time to 'target' excited species, the latter of which has been identified by FEW as a 'grand challenge' in LTP science.
