Detection of coherent beam-beam modes with digitized beam position monitor signals
G. Stancari, A. Valishev, S. M. White
A system for bunch-by-bunch detection of transverse proton and antiproton coherent oscillations in the Fermilab Tevatron collider is described. It is based on the signal from a sin…
Measurements of the effect of collisions on transverse beam halo diffusion in the Tevatron and in the LHC
G. Stancari, G. Annala, T. R. Johnson +9
Beam-beam forces and collision optics can strongly affect beam lifetime, dynamic aperture, and halo formation in particle colliders. Extensive analytical and numerical simulations…
Beam-beam compensation studies in the Tevatron with electron lenses
Giulio Stancari, Alexander Valishev
At the Fermilab Tevatron collider, we studied the feasibility of suppressing the antiproton head-on beam-beam tune spread using a magnetically confined 5-keV electron beam with Gau…
Electron Lens as Beam-Beam Wire Compensator in HL-LHC
A. Valishev, G. Stancari
Current wires are considered for compensation of long-range beam-beam interactions for the High Luminosity upgrade (HL-LHC) of the Large Hadron Collider at CERN. In this note, we d…
The Advanced Superconducting Test Accelerator (ASTA) at Fermilab: A User-Driven Facility Dedicated to Accelerator Science \& Technology
P. Piot, V. Shiltsev, S. Nagaitsev +4
Fermilab is currently constructing a superconducting electron linac that will eventually serve as the backbone of a user-driven facility for accelerator science. This contribution…
Design and Simulation of IOTA - a Novel Concept of Integrable Optics Test Accelerator
S. Nagaitsev, A. Valishev, V. V. Danilov +1
The use of nonlinear lattices with large betatron tune spreads can increase instability and space charge thresholds due to improved Landau damping. Unfortunately, the majority of n…
