CMS Pixel Telescope Addition to T-980 Bent Crystal Collimation Experiment at the Tevatron
Ryan Rivera, Jerry Annala, Todd Johnson +7
An enhancement to the T-980 bent crystal collimation experiment at the Tevatron has been completed. The enhancement was the installation of a pixel telescope inside the vacuum-seal…
Beam halo dynamics and control with hollow electron beams
G. Stancari, G. Annala, A. Didenko +15
Experimental measurements of beam halo diffusion dynamics with collimator scans are reviewed. The concept of halo control with a hollow electron beam collimator, its demonstration…
Tevatron Beam Halo Collimation System: Design, Operational Experience and New Methods
Nikolai Mokhov, Jerry Annala, Richard Carrigan +10
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 supercon…
Advanced Bent Crystal Collimation Studies at the Tevatron (T-980)
V. Zvoda, G. Annala, R. Carrigan +16
The T-980 bent crystal collimation experiment at the Tevatron has recently acquired substantial enhancements. First, two new crystals - a 16-strip one manufactured and characterize…
Channeling and Volume Reflection Based Crystal Collimation of Tevatron Circulating Beam Halo (T-980)
V. Shiltsev, G. Annala, A. Drozhdin +15
The T980 crystal collimation experiment is underway at the Tevatron to determine if this technique could increase 980 GeV beam-halo collimation efficiency at high-energy hadron col…
Development of hollow electron beams for proton and ion collimation
G. Stancari, A. I. Drozhdin, G. Kuznetsov +6
Magnetically confined hollow electron beams for controlled halo removal in high-energy colliders such as the Tevatron or the LHC may extend traditional collimation systems beyond t…
