Title: Beam position monitor for energy recovered linac beams

Abstract

A method of determining the beam position in an energy recovered linac (ERL). The method makes use of in phase and quadrature (I/Q) demodulation techniques to separate the pickup signal generated by the electromagnetic fields generated by the first and second pass beam in the energy recovered linac. The method includes using analog or digital based I/Q demodulation techniques in order to measure the relative amplitude of the signals from a position sensitive beam pickup such as a button, strip line or microstripline beam position monitor.

Use of off-axis injection as an alternative to geometrically merging beams in an energy-recovering linac

Patent Douglas, David R [York County, VA]

A method of using off-axis particle beam injection in energy-recovering linear accelerators that increases operational efficiency while eliminating the need to merge the high energy re-circulating beam with an injected low energy beam. In this arrangement, the high energy re-circulating beam and the low energy beam are manipulated such that they are within a predetermined distance from one another and then the two immerged beams are injected into the linac and propagated through the system. The configuration permits injection without geometric beam merging as well as decelerated beam extraction without the use of typical beamline elements.

Integral window/photon beam position monitor and beam flux detectors for x-ray beams

Patent Shu, Deming [Darien, IL]; Kuzay, Tuncer M [Naperville, IL]

A monitor/detector assembly in a synchrotron for either monitoring the position of a photon beam or detecting beam flux may additionally function as a vacuum barrier between the front end and downstream segment of the beamline in the synchrotron. A base flange of the monitor/detector assembly is formed of oxygen free copper with a central opening covered by a window foil that is fused thereon. The window foil is made of man-made materials, such as chemical vapor deposition diamond or cubic boron nitrate and in certain configurations includes a central opening through which the beams are transmitted.

Photon beam position monitor

Patent Kuzay, Tuncer M [Naperville, IL]; Shu, Deming [Darien, IL]

A photon beam position monitor for use in the front end of a beamline of a high heat flux and high energy photon source such as a synchrotron radiation storage ring detects and measures the position and, when a pair of such monitors are used in tandem, the slope of a photon beam emanating from an insertion device such as a wiggler or an undulator inserted in the straight sections of the ring. The photon beam position monitor includes a plurality of spaced blades for precisely locating the photon beam, with each blade comprised of chemical vapor deposition (CVD) diamondmore » « less

Beam position monitor

Patent Alkire, Randy W.; Rosenbaum, Gerold; Evans, Gwyndaf

An apparatus for determining the position of an x-ray beam relative to a desired beam axis. Where the apparatus is positioned along the beam path so that a thin metal foil target intersects the x-ray beam generating fluorescent radiation. A PIN diode array is positioned so that a portion of the fluorescent radiation is intercepted by the array resulting in an a series of electrical signals from the PIN diodes making up the array. The signals are then analyzed and the position of the x-ray beam is determined relative to the desired beam path.

Patent VanZwienen, William H [Bayshore, NY]

A support means for a plurality of thermally deformable component parts that are concentrically mounted within a thermally expandable housing. The support means includes a plurality of pins that are mounted in relatively fixed or sliding relationship to either one of the concentrically positioned components or to the housing, and the pins are positioned to extend through aligned apertures in the remaining components or the housing in a manner such that the pins are free to slide in a snug relationship relative to the sides of the holes through those components or the housing.
