Scanning Electron Beam Profile Monitor
A scanning beam profile monitor is described that was developed for use along the Stanford two-mile linear accelerator. The maximum beam loss due to scattering caused by this monitor can be made to be a small fraction of that which would be caused by a Cerenkov radiator or scintillating screen. (To be submitted to the Review of Scientific Instruments) * Work supported by the U. S. Atomic Energy...
متن کاملBeam Profile Wire-scanner/halo-scraper Sensor Analog Interface Electronics
The halo experiment presently being conducted at the Low Energy Demonstration Accelerator (LEDA) at Los Alamos National Laboratory utilizes a generally traditional wire scanner for measurement of the beam core profile and a graphite scraper for measurement of the tails of the beam distribution. A lossy integrator is used to detect the replacement charge flowing to the wire and scraper. Independ...
متن کاملNanomechanical vibrating wire resonator for phonon spectroscopy in liquid helium
We demonstrate how to machine a vibrating wire resonator for ultrasonic excitations in gaseous and liquid helium. This novel resonator is designed as a nanoscopic mechanically flexible bridge machined out of a semiconductor/metal hybrid. Quenching of the mechanical resonance around 100 MHz in gaseous and liquid 4He at 4.2 K is shown. Vibrating wire resonators (VWRs) are standard bolometers for ...
متن کاملBeam alignment for scanning beam interference lithography
By interfering two small diameter Gaussian laser beams, scanning beam interference lithography ~SBIL! is capable of patterning linear gratings and grids in resist while controlling their spatial phase distortions to the nanometer level. Our tool has a patterning area that is up to 300 mm in diameter. The motive for developing SBIL is to provide the semiconductor industry with a set of absolute ...
متن کاملGolden beam data for proton pencil-beam scanning.
Proton, as well as other ion, beams applied by electro-magnetic deflection in pencil-beam scanning (PBS) are minimally perturbed and thus can be quantified a priori by their fundamental interactions in a medium. This a priori quantification permits an optimal reduction of characterizing measurements on a particular PBS delivery system. The combination of a priori quantification and measurements...
