Duncan Barlow (University of Bordeaux): Optimization of Polar Direct Drive Illumination for Mega-Joule Laser Facilities

- Export as iCalendar
Location: PS1.28

Abstract: I will present the use of Bayesian optimisation, gradient descent and genetic algorithms to produce improved laser parameters for polar direct drive. Laser inertial confinement fusion (ICF) now enters the regime of ignition, the next step is higher energy yield which requires coupling more energy to the target. Laser direct drive achieves improved coupling as there is no hohlraum acting as an intermediary. However, the mega-joule laser facilities (National Ignition Facility and Laser Mega-Joule) are configured with beams entering at the poles for indirect drive, and so require beam re-pointing to recover a direct-drive compatible illumination. A polar direct drive scheme has already been tested on the NIF, however the irradiation configuration may not be optimal. The National Ignition Facility features: 8 cones of quads with independent wavelength tuning; 48 quads entering from different ports with independent pointing, power balance and defocusing; and the quads may be split to 192 beams with individual pointing offsets. There is a large parameter space which likely features different optimal setups for solid target illumination, conventional hotpot ignition, and shock ignition.

UKRI Deadlines

Due to the implementation of a new UKRI funding system (TFS) there will be a fixed quarterly deadlines for some grants which would previously have been on open calls, this is to allow necessary system amendments and updates.

The first deadline after implementation will be 28th September 2023 and applies to those calls listed below:

EPSRC New Investigator Award

EPSRC Network Grant

EPSRC Post Doctoral Fellowship

EPSRC Open Fellowship

EPSRC Open Plus Fellowship

EPSRC Working with overseas scientists

EPSRC Standard research grant

EPSRC Discipline hopping in ICT

EPSRC Overseas travel grant
