Autonomous Control of a Particle Accelerator using Deep Reinforcement Learning
Xiaoying Pang, Sunil Thulasidasan, Larry Rybarcyk
We describe an approach to learning optimal control policies for a large, linear particle accelerator using deep reinforcement learning coupled with a high-fidelity physics engine.…
Modeling of H- ion source at LANSCE
Nikolai Yampolsky, Ilija Draganic, Lawrence Rybarcyk
We report on the progress in modelling performance of the H- ion source at LANSCE. The key aspect we address is the lifetime of the tungsten filament. The lifetime depends on multi…
H-Mode Accelerating Structures with PMQ Beam Focusing
Sergey S. Kurennoy, Lawrence J. Rybarcyk, James F. O'Hara +2
We have developed high-efficiency normal-conducting RF accelerating structures by combining H-mode resonator cavities and a transverse beam focusing by permanent-magnet quadrupoles…
Determining Phase-Space Properties of the LEDA RFQ Output Beam
W. P. Lysenko, J. D. Gilpatrick, L. J. Rybarcyk +4
Quadrupole scans were used to characterize the LEDA RFQ beam. Experimental data were fit to computer simulation models for the rms beam size. The codes were found to be inadequate…
High Power Operations of LEDA
L. M. Young, L. J. Rybarcyk, J. D. Schneider +2
The LEDA RFQ, a 350-MHz continuous wave (CW) radio-frequency quadrupole (RFQ), successfully accelerated a 100-mA CW proton beam from 75 keV to 6.7 MeV. We have accumulated 111 hr o…
LEDA Beam Operations Milestone and Observed Beam Transmission Characteristics
L. J. Rybarcyk, J. D. Schneider, H. V. Smith +2
Recently, the Low-Energy Demonstration Accelerator (LEDA) portion of the Accelerator Production of Tritium (APT) project reached its 100-mA, 8-hr CW beam operation milestone. LEDA…
