Report

A Future Polarized Drell-Yan Experiment at Fermilab

Autor: Kleinjan, David

One of the great challenges of QCD is trying to understand the origin of the nucleon spin. Several decades of experimental measurements have shown that our current understanding is incomplete if only the quark and gluon spin contribution is considere

Report

Measurement of the transverse Single Spin Asymmetry of Forward Eta Mesons in $p^{\uparrow}+p$ Collisions in PHENIX

Autor: Kleinjan, David

Polarized $p+p$ collisions provide insight into the structure of the nucleon. $A_N$ of eta mesons at forward rapidities are of particular interest, as asymmetries of other mesons observed both by PHENIX and other experiments show significant deviatio

Report

Measurement of the Transverse Single Spin Asymmetry of $p$ + $p^\uparrow$ $\rightarrow$ $\eta$ + $X$ at $\sqrt{s}$ = 200 GeV

Autor: Kleinjan, David

Publikováno v: Journal of Physics: Conference Series, Volume 295 012085 (2011)

The measurement of transverse single spin asymmetries ($A_N$) provides insight into the structure of the nucleon. Several mechanisms have been proposed that attempt to explain $A_N$ based on QCD, and additional measurements of $A_N$ for different pro

Transverse single spin and azimuthal asymmetries in hadronic collisions at PHENIX

Autor: Kleinjan David

Publikováno v: EPJ Web of Conferences, Vol 85, p 02029 (2015)

Inclusive transverse single spin asymmetries from high energetic polarized proton proton collisions provide insight into the spin-momentum correlations in QCD. Originally expected to be small in collinear perturbative QCD, results from PHENIX and oth

Operating the SNS RF H⁻ Ion Source with a 10% Duty Factor

Autor: Stockli, Martin, Clemmer, Michael, Cousineau, Sarah, Draganic, Ilija, Dudnikov, Vadim, Garnett, Robert, Han, Baoxi, Justice, Thomas, Kang, Yoon, Kleinjan, David, Murray, Syd, Pennisi, Terry, Piller, Chip, Rouleau, Gary, Stinson, Chris, Welton, Robert

The SNS (Spallation Neutron Source) (radio-frequency) RF-driven, H⁻ ion source injects ~50 mA of H⁻ beam into the SNS accelerator at 60 Hz with a 6% duty factor. It injects up to 7 A·hrs of H⁻ ions during its ~14-week service cycles, which is

H⁺ and H⁻ Ion Beam Injectors at LANSCE: Beam Production Status and Planned Injector Upgrades

Autor: Draganic, Ilija, Kleinjan, David, Rouleau, Gary

The Los Alamos Neutron Science Center operates with two 750 keV Cockcroft-Walton accelerators for simultaneous injection of H⁺ and H⁻ ion beams into a 800 MeV linear accelerator. The proton ion beam is produced using a duoplasmatron source and th
