New Experimental Capabilities• Raman Spectroscopy
o Doing with fibers, but limited in sensitivity and geometrieso Split Helix gives large angleso Carbon and semiconductor based nanostructures (graphene, quantum wells,…), phase
transitions, HTS, quantum spin systems…• THz-Time Domain Spectroscopy
o generate low power broadband short pulseso uses FFT to recover both amplitude and phase information from interaction with sampleo ac conductivity of superconductors in high fields, cyclotron resonances…
• Optical 2D Fourier Transform Spectroscopy and 4-wave Mixingo sensitive interferometery that combines 3 or more beams of lighto cutting edge techniques, impossible without the Split-Helixo probes excitonic systems and their dynamics
• Improving existing methods:o Photoluminescenceo 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
