7663077, Feb 16, 2010

Filed:

Oct 27, 2006

Appl. No.:

11/589010

Inventors:

Michael W. Smith - Newport News VA, US
Kevin Jordan - Newport News VA, US

Assignee:

Jefferson Science Associates, LLC - Newport News VA

International Classification:

H05B 6/02
B23K 26/02
B23K 26/08
D01F 9/12

US Classification:

219601, 2191216, 21912185, 4234471, 977844

Abstract:

An RF-induction heated side-pumped synthesis chamber for the production of carbon nanotubes. Such an apparatus, while capable of producing large volumes of carbon nanotubes, concurrently provides a simplified apparatus that allows for greatly reduced heat up and cool down times and flexible flowpaths that can be readily modified for production efficiency optimization.

US Classification:

219601, 2191216, 21912185, 4234471, 977844

Abstract:

An improved method for the production of single walled carbon nanotubes that utilizes an RF-induction heated side-pumped synthesis chamber for the production of such. Such a method, while capable of producing large volumes of carbon nanotubes, concurrently permits the use of a simplified apparatus that allows for greatly reduced heat up and cool down times and flexible flowpaths that can be readily modified for production efficiency optimization. The method of the present invention utilizes a free electron laser operating at high average and peak fluence to illuminate a rotating and translating graphite/catalyst target to obtain high yields of SWNTs without the use of a vacuum chamber.

Appl. No.:

10/188525

International Classification:

B23K 26/12

US Classification:

21912186, 21912184, 2191216

Abstract:

Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces an output above about 50 watts/cmat a repetition rate above about 15 MHz and exhibits a pulse duration below about 10 picoseconds. The carbon, carbon/catalyst target and the laser beam are moved relative to one another and a focused flow of “side pumped”, preheated inert gas is introduced near the point of ablation to minimize or eliminate interference by the ablated plume by removal of the plume and introduction of new target area for incidence with the laser beam. When the target is moved relative to the laser beam, rotational or translational movement may be imparted thereto, but rotation of the target is preferred.

International Classification:

H05H 9/00

US Classification:

315505, 372 2, 372 29022, 2504923

Abstract:

The introduction of a magnetic electron beam orbit chicane between the wiggler and the downstream initial bending dipole in an energy recovering Linac alleviates the effects of radiation propagated from the downstream bending dipole that tend to distort the proximate downstream mirror of the optical cavity resonator.
