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

  5. Shopping List • U-shaped non-magnetic optical table around magnet (150 k$) • Optical windows, custom vacuum hardware… (200 k$) • Dewar/cryosystemmounted to optical table (350 k$) • Vibration isolation between dewar and magnet (100 k$) • Narrow band Krypton laser for Raman Spectroscopy (100 k$) • Time correlated photon counter (100 k$) • Micropositioners & rotators, high B/low T (400 k$) • Optics, detectors, etc (400 k$) • New Bruker FTIR spectrometer with microscope (250 k$) • New, small footprint one-box amplifier ultrafast laser system (1 M$) • Custom made ultra low frequency Raman Scattering spectrometer (including custom microscope) (1 M$)

  6. Personnel • Technician – being hired • 3 Postdocs – optics, FTIR, micro-Raman/optics • Grad Students • Senior Faculty Member?

  7. Installation into Cell 5 Open wall to Optics Cell (3), extend ceiling, 100 k$
