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 Intensity Profile Monitor
This paper describes an intercepting beam intenSity profile and position monitor which was developed at SLAC. It has excellent spatial resolution as well as signal efficiency. The instrument utilizes the electromagnetic cascade shower emission effect. Net charge leakage signals comparable in magnitude to the intercepted beam current are easily obtainable. The latest model of the instrument is d...
متن کاملLaser-based Profile Monitor for Electron Beams*
High performance TeV energy electron / positron colliders (LC) are the first machines to require online, non-invasive beam size monitors for micron and submicron for beam phase space optimization. Typical beam densities in the LC are well beyond the threshold density for single pulse melting and vaporization of any material, making conventional wire scanners ineffective. Using a finely focused,...
متن کاملScanning-beam electron microscopy of Mycoplasma pneumoniae.
The morphology and the existence of a growth cycle of Mycoplasma pneumoniae have not been clearly established. There is disagreement as to whether this organism exists as a spherical or filamentous form, and whether it progresses from filamentous to spherical forms as the organism ages. A scanning-beam electron microscope (SEM) was utilized to provide detailed observations of the cycle of morph...
متن کاملNorth-Holland, Amsterdam RESIDUAL GAS BEAM PROFILE MONITOR
The design and performance of a beam profile monitor which presents no material to the beam is described. The detector, which has a 75 mm active width, operates from residual gas in the beam vacuum system . It provides 1 mm rms spatial resolution and 1 ms time resolution in a 1 ALA beam at 10-7 Torr . Using a microprocessor based scanning ADC, a sequence of ten profiles can be acquired in as li...
