Ion-matrix sheaths inside cylindrical bores with small radii and longitudinal grooves

2004-02-01
Demokan, O
In this paper, ion-matrix sheaths inside infinitely long cylindrical bores with longitudinal grooves are studied analytically to optimize ion implantation, concerning a broad range of industrial products. The radius of the cylindrical target is assumed to be less than the sheath length to simulate realistic targets, such as barrels and muzzles. The potential profiles inside and outside the grooves are derived and the ion velocity components inside the grooves are estimated. Finally, suggestions for improving the implantation uniformity on the surfaces of such targets are stated.

Angular coefficients of Z bosons produced in pp collisions at root S=8 TeV and decaying to mu(+)mu(-) as a function of transverse momentum and rapidity
Khachatryan, V.; et. al. (Elsevier BV, 2015-11-01)
Measurements of the five most significant angular coefficients, A(0) through A(4), for Z bosons produced in pp collisions at root S = 8 TeV and decaying to mu(+)mu(-) are presented as a function of the transverse momentum and rapidity of the Z boson. The integrated luminosity of the dataset collected with the CMS detector at the LHC corresponds to 19.7 fb(-1). These measurements provide comprehensive information about the Z boson production mechanisms, and are compared to the QCD predictions at leading orde...
Ion-matrix sheaths related to planar targets with semicylindrical grooves
Demokan, O; Filiz, Y (AIP Publishing, 2003-01-01)
In this work, the ion-matrix sheaths near planar targets with infinitely long, semicylindrical grooves are studied analytically to optimize ion implantation, concerning a broad range of industrial products. The potential profiles inside and outside the groove are derived and the velocity components inside the groove are estimated. The variation of the angle of incidence on the surface of the groove and the constant potential contours outside the groove are obtained. Results are observed to be in good agreem...
Vector boson production in association with jets at CMS
Yalvaç, Metin; ÖCALAN, KADİR (2018-07-06)
The production cross section of highly boosted vector bosons (V = W, Z or gamma) recoiling against jets is studied, with CMS data, differentially as function of the transverse momentum and angular correlations of the final state particles. The measurements are confronted with different state-of-the-art theory predictions that include next-to-leading order calculations and matrix-element plus parton shower event simulations.
Edge currents in non commutative Chern Simons theory from a new matrix model
BALACHANDRAN, Aiyalam P; GUPTA, Kumar S; Kürkcüoğlu, Seçkin (Springer Science and Business Media LLC, 2003-09-01)
This paper discusses the formulation of the non-commutative Chern-Simons (CS) theory where the spatial slice, an infinite strip, is a manifold with boundaries. As standard *-products are not correct for such manifolds, the standard non-commutative CS theory is not also appropriate here. Instead we formulate a new finite-dimensional matrix CS model as an approximation to the CS theory on the strip. A work which has points of contact with ours is due to Lizzi, Vitale and Zampini where the authors obtain a des...
Measurement of normalized differential t(t)over-bar cross sections in the dilepton channel from pp collisions at root s=13 TeV
Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2018-04-01)
Normalized differential cross sections for top quark pair production are measured in the dilepton (e(+)e(-), mu(+)mu(-), and mu(-/+),e(+/-)) decay channels in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements are performed with data corresponding to an integrated luminosity of 2.1 fb(-1) using the CMS detector at the LHC. The cross sections are measured differentially as a function of the kinematic properties of the leptons, jets from bottom quark hadronization, top quarks, and...
