Courses related to Warp:
Background material on the numerical simulation of space-charge dominated beams can be found in a series of lecture notes by S.M. Lund, J.-L. Vay, and R. Lehe on Self-Consistent Simulation of Beam and Plasma Systems. The course covers numerical methods employed within Warp in the context of self-consistent modeling of intense beams and plasmas, and Warp is prominently used in examples. So the course serves, in part, as an introduction to using Warp. This graduate-level course should be offered at the US Particle Accelerator School (USPAS) approximately every two years. After the initial version (2016, 1.5 semester hours), the course will be a three semester hour equivalent course given over two weeks (intensive school format), and can be taken for university credit.
Background material on the physics of space-charge dominated beams can be found in an extensive set of course lecture notes by S.M. Lund and J.J. Barnard on Beam Physics with Intense Space Charge. This graduate-level course has been taught as part of the US Particle Accelerator School (USPAS) since 2001. The lecture notes are useful for background on the physics models in Warp and properties of intense beams. The course is being offered in the USPAS approximately every 2 years, is a three semester hour equivalent course given over two weeks (intensive school format), and can be taken for university credit.
