High Temperature Spectrometer Block Diagram Below is a block diagram of the high temperature millimeter/submillimeter-wave spectrometer. The radiation source, detector, and phase-locking electronics are identical to the low temperature spectrometer. The main differences concern the reaction chamber and the optics scheme. The reaction chamber is a double-walled, water-cooled steel vacuum cell, which contains three Broida-type oven ports. The optics scheme replaces the teflon lenses with two offset ellipsoidal mirrors (Reflectors 1 & 2) and a mylar window at the front of the reaction chamber. A path-length modulator is employed for baseline smoothing.
