Patent number: 10855262Abstract: A parallel Marx generator topology capable of producing high power, high current output pulses is provided. The parallel Marx generator topology can include a plurality of Marx generators that operate in parallel to one another to jointly generate an output pulse. The topology can further include a pulse transformer configured to step up the voltage of the pulse created by the plurality of generators and also ensure that each Marx generator of the plurality of Marx generators is outputting substantially the same amount of current. The system can include a common interface that allows for fault detection and control of all the Marx generators using one common control panel. The parallel Marx generator topology can allow for a high voltage, high current pulse to be generated using import/export compliant switches.Type: GrantFiled: June 19, 2018Date of Patent: December 1, 2020Assignee: Stangenes Industries, Inc.Inventors: Christopher Yeckel, Kelli Noel, Magne Stangenes, Paul Holen, Randy Ross, Richard Cassel, Sherry Hitchcock

Patent number: 10212799Abstract: A device and method for generating pulses to activate and deactivate a kicker magnet is provided. When the kicker magnet is deactivated the circuit generates and stores a magnetic field in an inductor. When the kicker magnet is activated, the circuit changes configuration so that the magnetic field and current stored in the inductor can provide the necessary current to activate the kicker magnet is a minimal amount of time. The configuration of the circuit changes via the use of switches. The switches can employ Zener diodes arranged so as to provide protection against high voltage events and rogue neutrinos that may bombard the switches when the kicker magnet is used in the context of deflecting a particle beam.Type: GrantFiled: February 8, 2017Date of Patent: February 19, 2019Assignee: Stangenes Industries, Inc.Inventors: Christopher Yeckel, Richard Cassel

Publication number: 20070146092Abstract: Systems and methods for generating a high voltage pulse. A series of voltage cells are connected such that charging capacitors can be charged in parallel and discharged in series. Each cell includes a main switch and a return switch. When the main switches are turned on, the capacitors in the cells are in series and discharge. When the main switches are turned off and the return switches are turned on, the capacitors charge in parallel. One or more of the cells can be inactive without preventing a pulse from being generated. The amplitude, duration, rise time, and fall time can be controlled with the voltage cells. Each voltage cell may also includes a balance network to match the stray capacitance seen by each voltage cell. Droop compensation is also enabled.Type: ApplicationFiled: March 7, 2007Publication date: June 28, 2007Applicant: STANGENES INDUSTRIES, INC.Inventor: Richard Cassel

Patent number: 5750808Abstract: A process is disclosed for the dehydrohalogenation of partially halogenated ethanes of the formula C.sub.2 H.sub.a Cl.sub.b F.sub.c where a is an integer from 1 to 4, b is an integer from 0 to 3 and c is an integer form 1 to 5 to produce olefins selected from the group consisting of C.sub.2 H.sub.a-1 Cl.sub.b-1 F.sub.c and C.sub.2 H.sub.a-1 Cl.sub.b F.sub.c-1. The process involves contacting C.sub.2 H.sub.a Cl.sub.b F.sub.c with a zeolite selected from the group consisting of NaX and CsY. Selective reaction of one isomer from a mixture of two isomers is disclosed as a means for purification of the relatively unreactive isomer. Also disclosed is a process for producing perfluorocyclobutane which involves contacting CHF.sub.2 CClF.sub.2 with such zeolites.Type: GrantFiled: July 9, 1996Date of Patent: May 12, 1998Assignee: E.
