Given that I didn't hear any dissent I have activated the project with Field/Subcat of P:Phy, priority 3 and assigned Steve Pieper as the POC. - JB On Mon, Aug 24, 2015 at 5:44 PM, [email protected] <[email protected]> wrote:

Hello,

A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee.

Applicant's name: John Power Applicant's institution: ANL Applicant's division: HEP Project Name: AWA-beam-dynamics Project title: High Accuracy Beam Dynamic Simulations Associated funding: Other Systems: Science: This project uses OPAL, a tool for charged-particle optics in accelerator structures and beam lines. In particular, we will use OPAL-T which can be used to model beam lines, linacs, rf-photo injectors and complete XFEL’s excluding the undulator. Realistic 3D beam dynamics simulations are used so that effects of couplers, vacuum pumping chambers, and other asymmetric features can be modeled. Project description: We intend to use this model to study the 3D effects of various asymmetric beamline components that cannot be accurately modeled in the usual 2D codes. Unlike 2-dimensional codes, OPAL is not restricted in the kind of geometry it can model. It is therefore possible to consider arbitrary shapes and their inclusion in beam dynamics and particle tracking calculations. Further, we plan to develop OPAL-T beyond its current capabilities to include realistic wakefield effects. Current wakefield effects are calculated with the rigid bunch approximation which is valid when the wakefield is weak and the beam is rigid. In the case of the Argonne Wakefield Accelerator (AWA) this assumption is not valid since the wakefield is very strong and the beam energy is low. The OPAL codes work very efficiently on parallel processors. It uses MPI and has demonstrated good speed-up efficiencies for over 1000 CPU's on the Cray XT5 at the Swiss Center for Scientific Computing.
