Patent number: 11589452Abstract: The present disclosures relates to an ion beam assembly where a relatively small deflection angle (approximately 15° from the center of the beam line) is used in conjunction with two beam dumps located on either side of the beam. In some embodiments, the combination of the two beam dumps and the magnet assembly can provide an ion beam filter. In some embodiments, the resulting system provides a smaller, safer and more reliable ion beam. In some embodiments, the ion beam can be a proton beam.Type: GrantFiled: May 5, 2017Date of Patent: February 21, 2023Assignee: Neutron Therapeutics, Inc.Inventors: Geoffrey Ryding, Takao Sakase, William H.

Patent number: 9883577Abstract: A continuous, thin layer of neutron source material, for example solid lithium, is formed into a belt. The belt is continuously advanced in front of a proton source to generate neutrons from the lithium target. Additionally, the belt is continuously cooled, as it passes through a gas cooling section. Through the continuous motion and cooling of the lithium target, the belt can provide an effective neutron source without melting the target neutron source material.Type: GrantFiled: April 24, 2017Date of Patent: January 30, 2018Assignee: Neutron Therapeutics, Inc.Inventors: Steven P.

Patent number: 8558486Abstract: A d.c. charged particle accelerator comprises accelerator electrodes separated by insulating spacers defining acceleration gaps between adjacent pairs of electrodes. Individually regulated gap voltages are applied across each adjacent pair of accelerator electrodes. In embodiments, the individually regulated gap voltages are generated by electrically isolated alternators mounted on a common rotor shaft driven by an electric motor. Alternating power outputs from the alternators provide inputs to individual regulated d.c. power supplies to generate the gap voltages. The power supplies are electrically isolated and have outputs connected in series across successive pairs of accelerator electrodes. The described embodiment enables an ion beam to be accelerated to high energies and high beam currents, with good accelerator stability.Type: GrantFiled: December 8, 2010Date of Patent: October 15, 2013Assignee: GTAT CorporationInventors: Theodore H.

Patent number: 8426829Abstract: An ion implanter has an implant wheel with a plurality of wafer carriers distributed about a periphery of the wheel. Each wafer carrier has a heat sink for removing heat from a wafer on the carrier during the implant process by thermal contact between the wafer and the heat sink. The wafer carriers have wafer retaining fences formed as cylindrical rollers with axes in the respective wafer support planes of the wafer carriers. The cylindrical surfaces of the rollers provide wafer abutment surfaces which can move transversely to the wafer support surfaces so that no transverse loading is applied by the fences to wafer edges as the wafer is pushed against the heat sink by centrifugal force. The wafer support surfaces comprise layers of elastomeric material and the movable abutment surfaces of the fences allow even thermal coupling with the heat sink over the whole area of the wafer.Type: GrantFiled: September 30, 2010Date of Patent: April 23, 2013Assignee: GTAT CorporationInventors: William H Leavitt, Theodore H Smick, Joseph Daniel Gillespie, William H Park, Paul Eide, Drew Arnold, Geoffrey Ryding

Patent number: 8324599Abstract: An ion implanter has an implant wheel with a plurality of wafer carriers distributed about a periphery of the wheel. Each wafer carrier has a heat sink for removing heat from a wafer on the carrier during the implant process by thermal contact between the wafer and the heat sink. A respective wafer lift structure on each carrier is moveable between first and second positions, with the wafer supported spaced away from the heat sink and in thermal contact with the heat sink respectively. The lift structure is operated to move between the first and second positions wheel the implant is rotating. This allows control of wafer temperature during the implant process by adjusting the thermal contact between wafers and heat sinks.Type: GrantFiled: September 29, 2009Date of Patent: December 4, 2012Assignee: Twin Creeks Technologies, Inc.Inventors: Theodore H.

Patent number: 8268645Abstract: A method for producing a lamina from a donor body includes implanting the donor body with an ion dosage and heating the donor body to an implant temperature during implanting. The donor body is separably contacted with a susceptor assembly, where the donor body and the susceptor assembly are in direct contact. A lamina is exfoliated from the donor body by applying a thermal profile to the donor body. Implantation and exfoliation conditions may be adjusted in order to maximize the defect-free area of the lamina.Type: GrantFiled: December 20, 2011Date of Patent: September 18, 2012Assignee: Twin Creeks Technologies, Inc.Inventors: Adam Kell, Robert Clark-Phelps, Joseph D.
