Science opportunities: Four main proposal thrusts

Examples stolen shamelessly from Chapter 2 of the Renewal Proposal

• Dynamic nuclear polarization

• Science above 100 T

• Big Light

• High field science across the disciplines

The next 10 years: emerging science opportunities

2+ 2 = 7: new facility combinations to leverage science

Single crystal

Challenges facing the user community

• need for more high field magnet time

• liquid helium – a scarce resource

• Lab’s ability to attract and retain top talent (We want to work with the best!)

• infrastructure renewal issues (power supplies, liquifiers, nmr consoles)

• how to fund new initiatives: Big Light, dynamic nuclear polarization

• centralized vs. distributed research capabilities

• broadening our impact: how to bring high field science to other fields and disciplines?

• increasing diversity (a few action items later)

• helping the NHMFL remain the premier lab for high field science in light of strong international competition

Need for increased magnet time: Magnet lab user base increased by 15% without increase in facilities

20-30% new PI’s every year – less time for long term users

Oversubscription of flagship magnets 50-100% Oversubscription of workhorse magnets 25-50%

Oversubscription rate not good indication of demand – user requests tend to align with available time.

User survey demonstrates this need.

More magnet time please!

Centralized vs. distributed infrastructure for the NHMFL

• Users come from a lot of different places

• If we distribute and duplicate facilities, we need the funding base to do it properly

• The concern: Siphoning off support for the NHMFL by building satellite facilities around country.

• Better: build premier facilities for high field science at a single lab

• Shared infrastructure reduces costs!

• International competition…

• Travel funding would help PIs

In the eyes of the competition December Issue of EuroMag News

Leveraging our science and infrastructure to remain on top

Other magnet labs are not sitting still…

Magnet technology development at the NHMFL

• very talented team of magnet developers • they work for us (Yes, we are SO lucky!)

– split coil – 100 T pulsed magnet – series connected hybrid – higher field, lower power resistive magnets – HTCS superconducting magnet – 50 or 60 T hybrid

• they are very responsive to user needs • let’s keep them working for us (rather than working for

others) • many magnet technology, materials processing, and clean

energy spin offs…

NHMFL breaks the megaGauss barrier, reaches 100.75 tesla pulse

100.75 tesla confirmed via magneto quantum oscillations in poly-crystalline copper. First nondestructive generation of magnetic fields

in excess of 100T as a research tool.

This effort represents the culmination of a 15-year project funded by:

What to do about diversity?

Attract, hire, retain. Provide opportunity. Do it with care. Over the long term.

2011 MagLab User Summer

School

25 Participants 12 Institutions represented 7 Different states 4 Different countries Ewha Womans University, Korea Florida State University, Florida Georgia State University, Georgia Institut fur Anorganische Chemie, Germany Los Alamos National Laboratory, New Mexico Oak Ridge National Laboratory, Tennessee Stanford University, California University of California, Berkeley, California University of Florida, Florida University of Oxford, United Kingdom University of Vermont, Vermont Virginia Tech University, Virginia Tech

Diversity among 25 Participants 10 from under-represented groups (40% from under-represented groups) 6 Women (24%) 3 Hispanic (12%) 2 African Americans (8%)

Summer and Winter Schools educate young people, develop teamwork, and build diversity

• Future of high field research in the US

• science drivers

• infrastructure opportunities

• bringing high field science to new fields

• improving diversity… slow but steady

• Real challenges ahead

• documented demand for more high field magnet time

• steady, long-term funding for the Lab and its initiatives

• international competition
