Publication number: 20240080965Abstract: A method for producing a neutrons includes triggering a raising or a lowering of a temperature of a pyroelectric crystal of less than about 40° C. to produce a voltage of negative polarity of at least ?100 keV on a surface of a deuterated or tritiated target coupled thereto. A deuterium ion source is pulsed to produce a deuterium ion beam. The accelerating of the deuterium ion beam is achieved by accelerating voltage of the pyroelectric crystal toward the deuterated or tritiated target to produce neutrons. Furthermore, the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source are coupled to a common support. The method also includes throwing the common support housing the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source near an unknown threat for identification thereof.Type: ApplicationFiled: October 3, 2023Publication date: March 7, 2024Inventors: Vincent Tang, Glenn A.

Patent number: 9560734Abstract: A non-radio-isotopic radiological source using a dense plasma focus (DPF) to produce an intense z-pinch plasma from a gas, such as helium, and which accelerates charged particles, such as generated from the gas or injected from an external source, into a target positioned along an acceleration axis and of a type known to emit ionizing radiation when impinged by the type of accelerated charged particles. In a preferred embodiment, helium gas is used to produce a DPF-accelerated He2+ ion beam to a beryllium target, to produce neutron emission having a similar energy spectrum as a radio-isotopic AmBe neutron source. Furthermore, multiple DPFs may be stacked to provide staged acceleration of charged particles for enhancing energy, tunability, and control of the source.Type: GrantFiled: February 22, 2010Date of Patent: January 31, 2017Assignee: Lawrence Livermore National Security, LLCInventors: Brian Rusnak, Vincent Tang

Patent number: 9105087Abstract: The inversion algorithm based on the maximum entropy method (MEM) removes unwanted effects in high energy imaging resulting from an uncollimated source interacting with a finitely thick scintillator. The algorithm takes as input the image from the thick scintillator (TS) and the radiography setup geometry. The algorithm then outputs a restored image which appears as if taken with an infinitesimally thin scintillator (ITS). Inversion is accomplished by numerically generating a probabilistic model relating the ITS image to the TS image and then inverting this model on the TS image through MEM. This reconstruction technique can reduce the exposure time or the required source intensity without undesirable object blurring on the image by allowing the use of both thicker scintillators with higher efficiencies and closer source-to-detector distances to maximize incident radiation flux.Type: GrantFiled: July 18, 2013Date of Patent: August 11, 2015Assignee: Lawrence Livermore National Security, LLCInventors: Han Wang, James M.

Patent number: 8749951Abstract: A two-phase mixed media insulator having a dielectric fluid filling the interstices between macro-sized dielectric beads packed into a confined volume, so that the packed dielectric beads inhibit electro-hydrodynamically driven current flows of the dielectric liquid and thereby increase the resistivity and breakdown strength of the two-phase insulator over the dielectric liquid alone. In addition, an electrical apparatus incorporates the two-phase mixed media insulator to insulate between electrical components of different electrical potentials. And a method of electrically insulating between electrical components of different electrical potentials fills a confined volume between the electrical components with the two-phase dielectric composite, so that the macro dielectric beads are packed in the confined volume and interstices formed between the macro dielectric beads are filled with the dielectric liquid.Type: GrantFiled: March 26, 2010Date of Patent: June 10, 2014Inventors: Steven Falabella, Glenn A.

Publication number: 20050004992Abstract: A mail server collects messages from a number of user accounts and presents them to the user from a single location. The user can set the mail server to block unwanted messages and to forward others to various receiving devices, including mobile telephones and pagers. Forwarded messages are automatically reformatted for the receiving device, while a copy of the original message is retained. The retained copy can be viewed later if the user is interested in message content that was not available to the wireless device. The user can also use the wireless device to forward the original message to another receiving device. In the case of forwarding, the saved original message and not the reformatted message is sent to the forwarding address. Some embodiments include an email agent that automatically pushes messages from intranet clients to the mail server through a firewall, thereby enabling the mail server to consolidate messages from intranet and Internet sources.Type: ApplicationFiled: August 17, 2004Publication date: January 6, 2005Inventors: Jens Horstmann, Ajay Giovindarajan, Alan Rothkopf, Tal Dayan, Arie Avnur, Justin Kitagawa, Carolyn Boyce, Aleksandr Schvartsman, Aswath Satrasala, Vincent Tang
