Larry Carr is the spokesperson for infrared beamlines U4IR & U10A, and local contact for infrared beamline U12IR. The U10A and U12IR beamlines serve the solid state physics community by providing for transmission and reflection spectroscopy of small material specimens over the spectral range from 5 cm[SUP]-1[/SUP] to beyond 5000 cm[SUP]-1[/SUP]. They also offer time-resolved spectroscopy to 300 ps in conjunction with a synchronized Ti:sapphire laser system. The U4IR beamline serves the BNL chemistry department’s program in corrosion and catalysis (surface vibrational spectroscopy) and also offers (through U10B) a scanning microspectrometer modified that reaches into the far-IR / THz spectral range.
