The calculated spectrum of coherent edge radiation emitted from the UCLA PBPL compressor experiment at BNL ATF shows large powers emitted from the several mm down to the 20 micron wavelength. The enhancement of edge radiation (which is a higher power transient artifact of synchrotron radiation at magnet edges) from compressed beam in this wavelength region has never been observed before. In order to spectrally resolve this radiation, a THz-to-far IR transport channel followed by a Winston cone (non-imaging collector) in being constructed, which is followed by a cold filter-wheel and bolometer assembly. The filters have cut-on wavelengths of 13, 27, 45, 103, and 285 microns; the He-cooled Si bolometer has excellent, linear sensitivity in this spectral region.
