TI - Non-Destructive Vertical Halo Monitor on the ESRF’s 6GeV Electron Beam
J2 - Proc. of IBIC2014
AB - The population density along the electron’s beam vertical profile at far distance from the central core (i.e. the far-away tails or “halo”) is now quantitatively measurable by the use of bending magnet X-rays. An available beamport is equipped with two specifically adapted absorbers, an Aluminium UHV window, an X-ray light blocker, an X-ray imager, and a few motorizations. The simple and inexpensive set-up (much resembling that of an X-ray pinhole camera system for emittance measurements in Light Sources, but much shorter in length) allows the recording of images of the electron density profile over the 0.5 to 6mm distance range from the core. Results, obtained under various manipulations on the electron beam to vary either Touchek or residual Gas scattering and thereby the Halo levels, will be presented, to fully demonstrate that this Halo monitor is exploring those realms of the beam where other diagnostics can not reach .
