Tevatron Beam Halo Collimation System: Design, Operational Experience and New Methods
Accelerator Subsystems and Technologies bent crystal collimation hollow electron beam collimation Accelerator Physics

Collimation of proton and antiproton beams in the Tevatron collider is required to protect CDF and D0 detectors and minimize their background rates, to keep irradiation of superconducting magnets unde...
Dynamical chaos in the problem of magnetic jet collimation
galaxies: jets – magnetic fi elds – MHD – ISM: jets and outfl ows – ISM:kinematics and dynamics
2011/10/12
We investigate dynamics of a jet collimated by magneto-torsional oscillations. The problem is reduced to an ordinary differential equation containing a singularity and depending on a parameter. We fin...
The influence of collimation on the appearance of relativistic jets
collimation relativistic jets
2011/1/13
The question of the collimation of relativistic jets is the subject of a lively debate in the community. We numerically compute the apparent velocity and the Doppler factor of a non homokinetic jet us...
Experiments to investigate the effects of radiative cooling on plasma jet collimation
radiative cooling plasma jet collimation
2010/11/12
Preliminary experiments have been performed to investigate the effects of radiative cooling on plasma jets. Thin (3 um - 5 um) conical shells were irradiated with an intense laser, driving jets with ...
