The Office of Basic Energy Sciences (BES), within the DOE’s Office of Science, is responsible for current and future user facilities including synchrotron radiation, free electron lasers, and the Spallation Neutron Source (SNS). This topic seeks the development of advanced, highly-parallel magnet design codes to support understanding and development of these user facilities. Grant applications that are not beyond the state-of-the-art nor do not fall within the topic will not be considered.

Grant applications are sought in the following subtopics:

a. Massively Parallel 3-D Magnet Design Codes

 

Available codes for 3-D modeling and design of electromagnet and permanent magnet systems have reached a high degree of sophistication and predictive accuracy. However, these codes suffer from either a total lack of parallelism or else poor parallel performance in applications that are relevant to particle accelerators. The lack of efficient parallelism leads to long turn-around times, which significantly hampers the design process. An example for which this is relevant is high-strength combined-function magnets for next-generation storage ring light sources.

In addition, serial magnet design codes suffer from memory limitations that significantly reduce the ability to obtain adequate detail and completeness in the magnet model. A significant factor is that accelerator magnets are physically large compared to the volume within which the particle beam travels. This significant difference in scales leads to competing requirements for the mesh size, leading to compromises in the accuracy of the predicted fields seen by the beam. Examples of systems for which this is a significant problem include: (1) septum magnets, which have a small, low-field bore for the stored beam separated by a thin material barrier from a relatively large, high-field bore for the incoming beam; (2) advanced insertion devices such as helical superconducting undulators, which have intricate conductor geometry at the ends; typically, such devices are simulated in sections, which leads to reduced fidelity (3) sequences of several closely-spaced magnets, as present in advanced multi-bend achromat lattices for next-generation storage ring light sources.

These issues can be resolved by a software system that incorporates an efficient parallel magnet modeling capability. In addition to efficient, highly parallel computation of magnetic fields, such a system would need to include basic features such as importation of geometry from external sources (e.g., CAD systems), generation of the problem mesh, saturable materials, permanent magnet materials, current-carrying conductors, optimization, and visualization.
