In the past, blackbody simulator cavity shapes have been chosen by intuition and experience, combined with selective comparisons among candidate cavity shapes using one or more blackbody simulator cavity theories. Popular candidates have included cones, cylinders, spheres, reentrant cones, and lidded cones and cylinders; the usual choices have been cones. This paper describes a new family of blackbody simulator cavity shapes with improved uniformity of cavity emissivity and a tendency toward uniform cavity temperature.
