We are pleased to announce that two members of the Muon Accelerator Program have been selected as recipients
of FY12 Early Career Research Program awards
from the U.S. Department of Energy. Congratulations to Tengming Shen of Fermilab and Pavel Snopok of the Illinois
Institute of Technology for their significant accomplishments.
Engineering High Field Superconducting Materials for Frontier Accelerator Technology
Dr. Tengming Shen, Associate Scientist
Superconducting Materials Department
Fermi National Accelerator Laboratory
The objective of this project is to transform high-field superconductors, particularly
Bi2Sr2CaCu2Ox, a high-temperature superconducting material that
has magnetic field upper limits surpassing 100 Tesla at 4.2 K and can be fabricated into a multifilamentary round wire,
to practical magnet conductors that can be used to generate fields above 20 Tesla for the next generation of accelerators.
Studies will focus on (1) understanding the micro- and nano-structures that produce high critical current density Jc
in long-length conductors through extensive electromagnetic measurements and innovative micro-structural characterizations;
(2) advancing high-temperature superconducting magnet engineering through designing, fabricating, and testing
Bi2Sr2CaCu2Ox insert coils that reach 30 Tesla in a useful aperture of >30 mm.
This research will result in a high-performance, 20-50 Tesla class conductor for the next generation of accelerators and
spectrometers for medical imaging and advanced materials research. The fundamental understanding gained of superconductor
synthesis and how nanostructure underpins the superconducting property will provide insights for the development of a
large class of superconducting materials for magnet and energy applications.
Advanced Simulation Tools for Muon–Based Accelerators
Dr. Pavel Snopok, Assistant Professor
Department of Physics
Illinois Institute of Technology
The objective of this project is to develop new modeling tools based on modern software frameworks, G4beamline and COSY Infinity, and to incorporate the most accurate theoretical calculations and experimental data available for crucial and not-yet-considered physics processes specific to muon accelerators. This study will substantially enhance the confidence that the tools used in assessing the feasibility of a muon collider or a neutrino factory will accurately represent the performance of a real machine. This work is critical to the support of long-range exploratory physics work aimed at developing new concepts. To pursue the computationally intensive analysis techniques required by this research, high-performance computing and general-purpose computation on graphics processing units will be employed. Tools developed during the project will be used on a daily basis to perform simulations that explore, evaluate, and validate the design of a muon collider that is the centerpiece of the national Muon Accelerator Program. Computer codes will be made accessible to the scientific community and will also be applicable to other existing and future muon facilities.
