A Multichannel Submillimeter Wave Interferometer System On Atf

A high resolution multichannel far-infrared interferometer has been constructed for the ATF experiment at Oak Ridge. The system consists of a pair of cw 119-pm methanol lasers, optically pumped by separate CO2 lasers. An external Stark-cell modulation scheme is used to stabilize the frequencies of the CO2 lasers. The system is designed to be operated, monitored, and stabilized by a PC computer.
