New Experimental Capabilities
•
Raman Spectroscopy
o Doing with fibers, but limited in sensitivity and geometries
o Split Helix gives large angles
o Carbon and semiconductor based nanostructures (graphene, quantum wells,…), phase
transitions, HTS, quantum spin systems…
•
THz-Time Domain Spectroscopy
o generate low power broadband short pulses
o uses FFT to recover both amplitude and phase information from interaction with sample
o ac conductivity of superconductors in high fields, cyclotron resonances…
•
Optical 2D Fourier Transform Spectroscopy and 4-wave Mixing
o sensitive interferometery that combines 3 or more beams of light
o cutting edge techniques, impossible without the Split-Helix
o probes excitonic systems and their dynamics
•
Improving existing methods:
o Photoluminescence
o Infrared magneto optics (FTIR…)
o EPR/ESR
Split magnet enables the ability to do “micro- spectroscopy”, imaging, etc. with
many techniques
X-ray opportunities
FEL opportunities
