In the Relativistic Heavy Ion Collider (RHIC) 100 GeV polarized proton run in 2015, two electron lenses were used to partially compensate for head-on beam-beam effect first time. Here, we describe design of current lens, detailing hardware modifications made after 2014 commissioning with heavy ions. A new gun 15-mm diameter cathode is characterized. The beam transverse profile was measured using a YAG screen and fitted Gaussian distribution. During operation, overlap beams achieved...
The Electron Ion Collider (EIC) calls for polarized helion on electron collisions. These collisions will require 1.2 × 1011 ions per bunch at 70% polarization. Meeting the EIC physics requirements maintaining both high efficiency and polarization transmission through accelerator complex. Polarized helions originate from Beam Source (EBIS) be injected into Booster |𝐺𝛾| = 4.1932. intensity EBIS is expected to 2 with a of 80%. In Booster, an AC dipole used spin-flip across intrinsic resonances...
In this paper, we use Boltzmann statistics and the maximum likelihood distribution derived from Bayes’ Theorem to infer parameter values for a Pake Doublet Spectrum, lineshape of historical significance contemporary relevance determining distances between interacting magnetic dipoles. A Metropolis Hastings Markov Chain Monte Carlo algorithm is implemented designed find optimum set estimate uncertainties. The posterior allows us define metric on space that induces geometry with negative...
The proposed eRHIC project is an electron hadron collider to be built in the existing tunnel of RHIC at Brookhaven National Laboratory (BNL). Polarized 3He+2 ions are one species collide with polarized electrons. To overcome spin resonances during pre-acceleration AGS-Booster, AC Dipole [2] being create artificial vertical intrinsic resonance which will eliminate naturally occurring acceleration. We present overview discuss physics and requirements overcoming using dipole, results from 2D 3D...
