27. Plasma processing for LCLS-II 1.3GHz SRF cavities

Bianca Giaccone

6/10/19, 11:00 AM

Oral

This study is focused on the development of an in-situ plasma cleaning procedure for 1.3GHz 9-cell TESLA shaped SRF cavities. The goal of this technique is to reduce field emission through the removal of adsorbed hydrocarbons that lower the work function of the cavity surface. In this work I present the first results of plasma processing applied to LCLS-II cavities focusing on plasma...

51. Simulation of Resonant Extraction at Fermilab's Delivery Ring

Mr Prudhvi Raj Varma Chintalapati (Chintalapati)

6/10/19, 11:15 AM

Oral

The Muon Campus at Fermilab presently houses two experiments that aim to find discrepancies (if any) in the Standard Model. The Delivery Ring is a 500m circumference storage ring which is used to deliver protons to muon experiments Muon g-2 and Mu2e. Although these experiments are based on the same particle, they require different intensities because of their detector constraints. For the Mu2e...

37. Design and analysis of a halo-measurement diagnostics

Mr Christopher Marshall (Northern Illinois University)

6/10/19, 11:30 AM

Oral

A large dynamical-range diagnostics (LDRD) design at Jefferson Lab will be used at the FAST-IOTA injector to measure the transverse distribution of halo associated with a high-charge electron beam. One important aspect of this work is to explore the halo distribution when the beam has significant angular momentum (i.e. is magnetized). The beam distribution is measured by recording radiation...

20. High Luminosity Spin-Polarized Target for the SpinQuest Experiment

Joshua Hoskins

6/10/19, 11:45 AM

Oral

The SpinQuest collaboration will measure the sea quark Sivers asymmetry using Drell-Yan production from the 120 GeV proton beam of the Fermilab Main Injector incident on transversely polarized proton and deuteron targets. Measuring a nonzero Sivers asymmetry would provide strong evidence for nonzero orbital angular momentum of sea quarks. The use of both polarized hydrogen and deuterium...

9. E1039/SpinQuest Polarized Drell-Yan Experiment at Fermilab

Dr Chun-Min Jen (Los Alamos National Lab)

6/10/19, 12:00 PM

Oral

E1039/SpinQuest is the first transversally-polarized Drell-Yan experiment at Fermilab. SpinQuest data-taking is anticipated to begin this coming fall 2019. In SpinQuest, a transversely-polarized NH3 or ND3 target is employed with the unpolarized 120-GeV extracted proton beam from Fermilab Main Injector to obtain various measurements of transverse single spin asymmetries in J/psi, psi’, lambda,...
