Segregating physics from chemistry from
biology is becoming increasingly less accurate
Equating a specific user program with a
specific discipline is becoming increasingly less
accurate

Big Light a Terahertz-to-Infrared Light Source
10
MagLab / JLab / UCSB collaboration
Addressing the Terahertz Gap between
electronics and optics
WE ARE HERE in the THIR for lt100M
NOT HERE where light sources cost 1B (i.e. BIG
MONEY)
Lasers have revolutionized our understanding of
the visible. We need a flashlight in the THIR
regime to illuminate phenomena that are now
invisible to research.

UNIQUE Co-located with worlds strongest

Generation synchrotrons)
UNIQUE Automatic time-synchronization of Near

THIR Laser
The THIR regime is a Science Blindspot
SEMICONDUCTORS
Band gaps/ widths
FOUR OF THE FIVE MAGLAB SCIENCE DRIVERS in
our (very successful) renewal proposal need
Big Light to understand energies involved in the
materials physics. Users want to leverage the
investment and flexibility of the MagLabs
magnets that manipulate these interesting
materials... ...that tune energies in the THIR
regime.

Energy Storage and Transfer Study Energy
Storage and Functionality of Nano-Magnets and
Metallo-proteins
Biological systems have hijacked metal atoms
to develop functionality (e.g. iron plays a
role in oxygenating blood as well as in
photosynthesis) BIG MAGNETS and BIG LIGHT can
take a stop-action video of electron motion
thru Intermediate states in biochemical
macrostructures like the photosynthesis center
(at right) Need a BRIGHT and FAST light
pulse for high speed electron spin resonance
studies of the intermediate steps taken by the
electron through the macrostructure to the metal
ion Need BIG MAGNETS to increase the sensitivity
of the electron spin resonance and to tune the
spin-split energy levels into the THIR regime to
probe the fast dynamics

X-rays can determine where the atoms are in big
biological molecules. But their function
comes from MOTION.

BIG MAGNETS too.

Physics and Chemistry at the Surface
Nanoparticles and Atoms on Surfaces make
Functionality New Catalysts, Hydrogen Storage,
Room Temperature Refining
BIG LIGHT will be multi-colored
(four different sources) and
different colored pulses will be
time-synchronized (within 20
femtoseconds) Thus, only BIG LIGHT will be able
to TICKLE with one beam (the pump) and watch
the resulting chemistry, wiggling, and
giggling of the nanoparticle, molecules and
atoms on the surface. Frequency-tuned
chemistry No longer confined to the
thermally-driven reaction pathways.
