Abstract :
The design and correction factor evaluation of a WR-15 (50 to 75 GHz) rectangular waveguide microcalorimeter is presented. This new microcalorimeter will be the US national standard for power from 50 to 75 GHz. It can measure the effective efficiency of a wider variety of transfer standards than can the previous microcalorimeter. It has also been designed so that its correction factor can be experimentally evaluated by multiple techniques.
