Presentation Transcript

  1. Hiring of a new EMR Director – Stephen Hill • Program growth:  New EMR lab with two new high frequency spectrometers* •  New push into biochemistry (future acquisition of HiPER)* •  Hiring of a new Scholar Scientist in biochemistry* •  Many new users, and increased numbers of users* • Major milestones:  World’s highest frequency pulsed EPR spectrometer (336 GHz) •  Expanded continuous frequency coverage to 1 THz (35 T for g=2)* •  High resolution EPR increased to 700 GHz in 25 T Keck magnet* •  Addition of Mössbauer spectroscopy to user instrumentation •  Development of EPR under pressure (separate NSF CHE funding) •  ~10% of NHMFL publications (~40 per year) •  Quality publications: JACS 11; PRL 9; Nature 1; Nature Physics 1; • PNAS 1; PRB 9; Inorg. Chem. 18; Dalton Trans. 5; Biochemistry 1. • *Specifically discussed in the previous renewal proposal Status and Highlights of the EMR Program

  2. Status and Highlights: EMR f = 934 GHz Commercial instruments

  3. Significant growth in the biological EPR program, built around HiPER (and the chem/bio Scholar/Scientist). HiPER, which will be acquired from St. Andrews University, offers a step-change in time resolution and sensitivity at 95 GHz. • Applications in site directed spin labeling in biomolecules, free radical chemistry/biochemistry, transition metal ion chemistry/biochemistry, catalysis, light emitting polymers, defects and impurities in semiconductors, molecular magnets and magnetic recording media as well as looking at applications in spintronics, nanophotonics and quantum computing. • Major involvement in the development of the BigLightFELand its users programs, including EMR program growth related these activities. • EMRprogram to become a major user of the new split-gap optical magnet and the series connected hybrid; the latter will enable even higher resolution at frequencies up to 1THz. • Education: Increased student and postdoctoral activity within the group • Organize a national interdisciplinary EPR school (1 week student workshop).
