Charged Particle Accelerator And Radiation Source

View page
US Patent:
8299713, Oct 30, 2012
Filed:
Sep 11, 2007
Appl. No.:
12/440799
Inventors:
Simon Martin Hooker - Oxford, GB
Anthony Joseph Gonsalves - Oxford, GB
Dino Anthony Jaroszynski - Glasgow, GB
Wim Pieter Leemans - Berkeley CA, US
Assignee:
Isis Innovation Limited - Oxford
International Classification:
H05B 31/26
H05H 1/54
G21K 5/00
US Classification:
31511121, 31511161, 31511171, 315505, 315507, 3133591, 3133621, 250395, 2504923
Abstract:
A method of accelerating charged particles using a laser pulse fired through a plasma channel contained in a capillary, wherein the plasma waveguide has deviations along its length that cause deviations in the plasma density contained therein, the deviations in plasma density acting to promote charged particle injection into a wake of a passing laser pulse. A radiation source based on a laser-driven plasma accelerator in a plasma waveguide in which the plasma waveguide and/or laser injection process is/are controlled so as to produce an undulating path for the laser pulse through the waveguide, the undulation exerting a periodic transverse force on charged particles being accelerated in the wake of the laser pulse, the resulting charged particle motion causing controlled emission of high frequency radiation pulses.

US Patent:
20180168024, Jun 14, 2018
Filed:
Feb 12, 2018
Appl. No.:
15/894422
Inventors:
- Oakland CA, US
Wim Leemans - Kensington CA, US
Stepan Bulanov - Concord CA, US
International Classification:
H05H 1/54
G21K 5/02
A61N 5/10
Abstract:
This disclosure provides systems, methods, and apparatus related to laser plasma accelerators. In one aspect a block of material defines a gas inlet, a chamber in fluid communication with the gas inlet, a throat in fluid communication with the chamber, a channel in fluid communication with the throat, and a gas outlet in fluid communication with the channel. The throat is configured to generate a supersonic flow of a gas when the gas flows through the throat. The channel includes a ramp that is positioned proximate the gas outlet, with the ramp being inclined at an angle with respect to a direction of a flow of the gas proximate a surface of the channel prior to the ramp at the gas outlet.
