Scientific paper

The design and performance of a simple 77-310-K black body for use as a sky-background simulator with a diffraction-limited submm-telescope simulator are reported. The temperature of a commercial microwave absorber is adjusted by varying the temperature of the gas passing through it. The results of tests of the thermal control and stability of the device and of emission measurements (with an iris aperture and chopper between the device and the He-4-cooled bolometric IR detector) are presented in graphs and discussed. The applicability of the black body as a laboratory FIR calibration source (possibly servo-controlled) is indicated.
