Daniel Bafia

Daniel Bafia is an associate scientist at the superconducting quantum materials and systems center at Fermilab studying the origins of RF loss in materials used in the fabrication of 3-D resonators and superconducting qubits. In addition to his research, he currently serves as the cavity technical lead at Fermilab for the LCLS-II HE project. He obtained his PhD from Illinois Institute of Technology in 2020 where he focused on understanding the origins of loss in niobium superconducting radio-frequency cavities which won him first place at the IPAC’19 conference student poster competition.

Daniel Davis

Dr. Daniel S. Davis has recently finished his Postdoc to start a Visiting Research Faculty position at the National High Magnetic Field Laboratory’s Applied Superconductivity Center. There he continues his work on ultra-high-field HTS magnet technology, driven by a strong passion for HTS technology R&D and the desire for mentoring students. Beginning with his PhD thesis studies of quench management of Bi-2212 magnets (FSU-Physics-2019), he has balanced experimental, simulation, and analysis efforts, leveraging and strengthening collaborations with the high energy physics community, particularly with the US-DOE-MDP and CERN. During a six- month stay at the LBNL with Dr. Tengming Shen, which was made possible by a DOE- SCGSR grant that he was awarded, he developed HTS quench simulations together with Dr. Emmanuele Ravaioli using LEDET (now part of CERN’s STEAM framework) for both UHF solenoids and HEP cable-wound dipoles to demonstrate a path to implementing Bi-2212 in full-scale industrial and accelerator magnets. His current work includes both HEP/fusion motivated cable-wound high field test solenoids of both Bi-2212 Rutherford cable and ReBCO CORC® as well as industry collaborations towards 25 T class compact research magnets and UHF NMR magnets beyond 30 T/1.2 GHz made with Bi-2212 round wire.

Simon Otten

Simon Otten obtained a MSc in applied physics from Twente University in 2014. After that he worked at Karlsruhe Institute of Technology as a PhD student on the topic of REBCO Roebel cables. Since 2019, he is a postdoctoral researcher at Twente University and is involved in research for different applications of superconductors, including Nb3Sn accelerator magnets and HTS linear motors.

Ricardo Donaton

Ricardo Donaton is a Senior Technical Staff Member in the IBM Quantum team working on quantum processor development, fabrication and delivery for quantum systems deployment. He currently leads the effort of developing new interconnects and packaging fab processes for quantum computing applications, bringing them from research into development. He has extensive experience in materials and technology development from his work at IBM Quantum, IBM Semiconductor Research and Development Center and IMEC.

During his career Ricardo has managed large and small teams of engineers and researchers from different nationalities and had the opportunity to go on an international assignment in France, acting as a technical lead for an emerging technology and also as project manager. This, combined with his Latino background – he was born and raised in São Paulo, Brasil – helped him to solidify a strong cross-cultural awareness. He is a member of the Hispanics@IBM community and a mentor in IBM. He received his Ph.D. in Physics from IMEC / Katholieke Universiteit Leuven, Belgium.

Dr. Ernesto Bosque

Ernesto Bosque is a Research Faculty member at the Applied Superconductivity Center at the National High Magnetic Field Lab (ASC-NHMFL). Following a B.S. in mechanical engineering from at the Florida State University, he continued at FSU to earn a PhD under Prof. S. Van Sciver at the NHMFL, experimentally investigating heat and mass transfer phenomena subsequent a catastrophic loss of the isolation vacuum around Helium-II systems. Transitioning from cryogenics, he began his superconducting magnet work under U. Trociewitz in the HTS Coils Group, focused on driving Bi-2212 high temperature superconductor technology into magnet technology. His postdoc focused on multiphysics finite element analysis on prototype coil designs to predict their operational performance limits and comparing the models with experimental results, which served as feedback to validate and improve the modeling effort.

As Bi-2212 requires a heat treatment at high temperature and pressure, another focus became a deeper understanding of the heat treatment. He heads operation of a large, high-pressure furnace required for processing the wind-and-react Bi-2212 coils for the coil program at the ASC, as well as for collaborations with industry and the US Magnet Development Program, specifically with LBNL. Over the last few years he has also taken on a Technology Manager role for insulated REBCO efforts within the NHMFL 40T All Superconducting Magnet Project. With over a decade of his career at the lab, he has also served as the Diversity Chair of the NHMFL for several years.

Lance Cooley

Prof. Lance Cooley is a Florida State University professor in the FAMU-FSU College of Engineering, Department of Mechanical Engineering, in addition to his MagLab roles as director of the Applied Superconductivity Center (ASC) and an associate lab director.

Cooley began his career in superconducting materials in 1986 at the University of Wisconsin – Madison, in the Applied Superconductivity Center under the direction of Prof. David Larbalestier. Lance’s early career, starting with his Ph.D. thesis, explored the ultimate limits of electric current in superconducting wires used for magnets. His thesis was awarded the Materials Research Society Graduate Award for the construction of periodic arrangements of flux-pinning centers at nanometer scale in superconducting wires. He earned a National Research Council Postdoctoral Fellowship at the National Institute of Standards and Technology in Boulder, Colorado, and later returned to Madison, Wisconsin, as a member of the research faculty to further investigate limits of superconductors.

The discovery of superconductivity in magnesium diboride in 2001 prompted Cooley to move to Brookhaven National Laboratory, where he eventually became head of the Superconducting Materials Group. He moved to Fermilab in 2007 to lead the SRF Materials Group, and later the Superconducting Materials Department. During this time, he coordinated external programs at multiple universities, laboratories and industry to improve performance of superconducting radio-frequency cavities and superconducting wires. This led to specifications and international standards related to niobium commerce, for which he received the International Electrotechnical Commission 1906 Award. He joined Florida State University and MagLab in 2017. He is also the manager of conductor acquisition for the Large Hadron Collider High-Luminosity Accelerator Upgrade Project as well as the head of Conductor Procurement and R&D for the National Magnet Development Program, both in the U.S. Department of Energy Office of High-Energy Physics.

Cooley serves as vice-president for publications for the IEEE Council on Superconductivity, which publishes the IEEE Transactions on Applied Superconductivity. He has served on many review panels of the U.S. Department of Energy and the National Science Foundation. He is a fellow of the Institute of Physics and a senior member of the Institute of Electrical and Electronic Engineers (IEEE). He has over 120 refereed publications, and has given more than 30 colloquia, plenary or public lectures.
