Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Nicole Neveu Project Name: AWA-beam-dynamics Division: HEP Project title: High Accuracy Beam Dynamic Simulations Associated funding: Other Systems: Science: This project is focused on the simulation of electron accelerators. In particular, we will use OPAL-t which can be used to model beam lines, linacs, and rf photoinjectors. Realistic 3D beam dynamics simulations are used so that effects of couplers, vacuum pumping chambers, and other asymmetric features can be modeled. These simulations will help provide better predictions in experiments carried out at the Argonne Wakefield Accelerator facility. Project description: The primary goal of this project is to simulate the two linear electron accelerators at the Argonne Wakefield Accelerator (AWA) facility using the open source, parallel, particle in cell code OPAL-t. All runs will be parallel, or run concurrently so that none of the allocation is used on single core jobs. The cores used vary from 4, 8, or 16 cores and can vary from 1 minute to several core hours. Our most common run at this time is 16 cores for ~7-10 minutes. This may vary with projects at the AWA, and given Bebop architecture. Current efforts include development of new optimization techniques to minimize the number of simulations needed to optimize the parameters of each beam line (current techniques require 50k-100k simulation evaluations). Since the AWA is a variable charge machine, optimization must be done for each experiment with different charge values, and this can be time intensive. Other work includes ongoing efforts to include 3D effects which more accurately model the accelerators. Simulations carried out at LCRC will improve operating conditions at the AWA.
