Performance of a 12.49 meter folded path copper Herriott cell designed for temperatures between 296 and 20 K
Résumé
Using a set of gold-coated copper mirrors identical to those reported previously we were able to increase the useful absorption path from 5.9 meters to 12.49 meters. The low temperature performance of the new cell is similar to that of the previously described cell. The testing procedure and results are described here.
