TL;DR: Experimental data revealed island structure in longitudinal phase space in synchrotron motion excited by phase modulation at the third harmonic of the syn chrotron frequency.
Journal ArticleDOI

TL;DR: In this paper, the synchroton motion of a beam was tracked by digitizing the phase of the beam signal from a high bandwidth wall gap monitor relative to the rf phase and the momentum deviation with a transverse beam position measurement in a high dispersion region.
Journal ArticleDOI
Density-dependent forces and large-basis structure models in the analyses of 12C(p, p') reactions at 135 MeV
W. Bauhoff,Stephen F Collins,R.S. Henderson,G.G. Shute,B.M. Spicer,V.C. Officer,K. Amos,Iain Morrison,D.W. Devins,D.L. Friesel,W.P. Jones +10 more
TL;DR: Differential cross sections have been measured for the elastic and inelastic scattering of 135 MeV protons from 12C using a distorted wave approximation with various microscopic model nuclear structure transition densities and free and density-dependent two-nucleon t-matrices as discussed by the authors.
Journal ArticleDOI

D. D. Caussyn,M. Ball,B. B. Brabson,J. Collins,S. A. Curtis,V. Derenchuck,D. DuPlantis,G. East,M. Ellison,Timothy J.P. Ellison,D.L. Friesel,B. Hamilton,W.P. Jones,W. Lamble,S. Y. Lee,Derun Li,M. G. Minty,T. Sloan,G. Xu,A. W. Chao,King Yuen Ng,S. Tepikian +21 more
TL;DR: The nonlinear beam dynamics of transverse betatron oscillations were studied experimentally at the Indiana University Cyclotron Facility cooler ring and the Hamiltonian for nonlinear particle motion near the third- and fourth-integer-resonance conditions has been deduced.
