The characteristics of a far IR spectroradiometer using a dewar with nearly 175 liters of superfluid helium at 2 deg K are examined. The device is to be flown as part of the LST (Large Space Telescope) payload and will allow observations in the IR with sensitivities and angular resolutions unachievable by ground-based, balloon-borne, or aircraft-mounted instruments. Two detectors will provide essentially background-limited detection over the spectral range. Analysis shows that 2 deg K cooling can be achieved and that the helium slosh presents no problem. Techniques for minimizing scan-generated noise are included in the instrument to ensure a successful instrument design. The effect of diffraction at the long wavelengths brought about by limited focal plane access is evaluated.
