Postdoctoral Appointee
Argonne National Laboratory
Job Description
About our Physics Division, ATLAS team:
The Argonne Tandem Linear Accelerator System (ATLAS) is the DOE/NP User Facility for the study of low energy nuclear physics with heavy ions. It operates ~6000 hours per year. While capable of delivering high intensities (up to ~1 pµA) of any available stable beam, the facility can also provide low intensity (103 – 106 particles per second) radioactive ion beams (RIB) from the Californium Rare Isotope Breeder Upgrade (CARIBU) source or via the in-flight process using the Argonne in-flight radioactive ion separator (RAISOR). The facility uses 3 ion sources and services 6 target areas at energies from ~1- 15 MeV/u.
To accommodate the total number of approved experiments along with their wide range of beam-related requirements, ATLAS reconfigures once or twice per week over 40 weeks of operation per year. The startup time varies from ~12 – 48 hours depending on the complexity, which will increase as the upcoming Multi-User Upgrade project is implemented over the next ~3 years to deliver beam to two experimental stations simultaneously. The use of machine learning and artificial intelligence has the potential of significantly reducing the time needed to tune the accelerator, and improve beam quality with the installation of new diagnostics and real-time data acquisition. These improvements will increase the scientific throughput of the facility and the quality of the data collected.
The AI/ML developments proposed in this project will be very beneficial to similar facilities and to the accelerator physics community at large.
