Measurements of Halo Generation for a Proton Beam in a Fodo Channel*
نویسنده
چکیده
An experimental effort has been undertaken to investigate the production of halo particles in a proton beam having significant space charge forces. The LEDA RFQ was used to inject a pulsed 6.7 MeV 1575 mA beam into a linear FODO channel. Four matching quads at the input of this 52-quadrupole transport line were used to generate specific mismatch oscillations, believed to be a key mechanism in the generation of beam halo. A suite of diagnostics that provide beam profile measurements over a wide dynamic range enabled a detailed comparison of measurements with theoretical models.

The Beam Halo Experiment at LEDA
Due to the potentially adverse effects of the generation of halo particles in intense proton beams, it is imperative to have a clear understanding of the mechanisms that can lead to halo formation for current and proposed high-intensity linacs. To this end a theoretical model has been developed, which indicates that protons under the combined influence of strong space charge forces and periodic...
متن کاملSns Injection Simulations with Space Charge
The SNS accumulator ring will have a high intensity (~ 10) low energy (1 GeV) beam and required uncontrolled particle loss rates of ~ one part in 10. For these beam parameters, space charge effects could drive beam halo growth, which would lead to violation of the stringent loss criterion. In this paper we investigate the transverse halo growth due to space charge using a newly developed simula...

Computational fluid dynamics analysis was employed to investigate the radial flow field patterns of proton exchange membrane fuel cells (PEMFC) with different channel geometries at high operating current densities. 3D, non-isothermal was used with single straight channel geometry. Our study showed that new generation of fuel cells with circle stack with the same active area and inlet area gave ...

A dual-halo dual-dielectric triple-material cylindrical-gate-all-around/surrounding gate (DH-DD-TM-CGAA/SG) MOSFET has been proposed and an analytical model for the transconductance-to-drain current ratio (TDCR) has been developed. It is verified that incorporation of dual-halo with dual-dielectric and triple-material results in enhancing the device performance in terms of improved TDCR. The ef...
متن کاملBeam Emittance Measurements and Beam Transport Optimisation at the Clatterbridge Cancer Centre*
The QUASAR Group is preparing tests of the high energy physics LHCb VELO detector as a non–invasive online dose monitor at the 60 MeV proton therapy beam at the Clatterbridge Cancer Centre (CCC), UK. The proposed method relies on the cross-correlation between the beam halo signal as measured by VELO and the dose delivered to the patient, linked via the absolute intensity of the beam. In order t...
