Abstract
Emisssivity is a prime most important factor that has to be known to calculate heat loads on the surfaces. The emissivity of the surface depends on the temperature of the surface. Due to the scarce of emissivity data at low temperatures, a calorimetry based experimental setup for emissivity measurement at cryogenic temperatures has been designed and fabricated. In this method the conduction and convection modes of heat transfer are reduced to the maximum extend by proper design and by maintaining high vacuum levels respectively. The setup allows measurement of emissivity of wide variety of metallic and non-metallic tapes and paints and components down to 90 K. The experimentally obtained total hemispherical emissivities with the available literature values of different samples, namely stainless steel, copper, aluminum tape, copper tape, kapton tape, aluminized Mylar and black paint are presented here.
Keywords- emissivity, cryogenic, cryostat and vacuum pumping
