Advanced Penning Ion Source

View page
US Patent:
20140070701, Mar 13, 2014
Filed:
Sep 4, 2013
Appl. No.:
14/018028
Inventors:
Thomas Schenkel - San Francisco CA, US
Qing Ji - Albany CA, US
Arun Persaud - El Cerrito CA, US
Amy V. Sy - Berkeley CA, US
Assignee:
The Regents of the University of California - Oakland CA
International Classification:
H01J 27/04
US Classification:
31511191
Abstract:
This disclosure provides systems, methods, and apparatus for ion generation. In one aspect, an apparatus includes an anode, a first cathode, a second cathode, and a plurality of cusp magnets. The anode has a first open end and a second open end. The first cathode is associated with the first open end of the anode. The second cathode is associated with the second open end of the anode. The anode, the first cathode, and the second cathode define a chamber. The second cathode has an open region configured for the passage of ions from the chamber. Each cusp magnet of the plurality of cusp magnets is disposed along a length of the anode.

US Patent:
20170076830, Mar 16, 2017
Filed:
Apr 29, 2016
Appl. No.:
15/143383
Inventors:
David R. Douglas - Yorktown VA, US
Rolland Paul Johnson - NewPort News VA, US
Andrew Kimber - Poquoson VA, US
Vasiliy S. Morozov - Yorktwon VA, US

Assignee:
Muons, Inc. - Newport News VA
International Classification:
G21G 1/12
H05H 7/22
H05H 9/00
Abstract:
A method and electron linac system for production of radioisotopes is provided. The electron linac is an energy recovery linac (ERL) with an electron beam transmitted through a thin bremsstrahlung radiator. Isotopes are produced through bremsstrahlung photon interactions in an isotope production target that is spatially separated from the bremsstrahlung radiator. The electron beam does not pass through the isotope production target. The electron beam energy is recollected and reinjected into the linac accelerating structure. The reduction of material in the beam by removing the isotope production target and making the radiator thin is the essential aspect of the invention because large spreads in energy and transverse scattering angles caused by material in the beam preclude efficient energy recovery. The method described here can reduce the cost of energy to produce a quantity of radioisotope by more than a factor of 3 compared to a non-ERL bremsstrahlung method.
