Abstract :
Recent improvements in the prototype of an ac-dc thermal transfer standard operating at cryogenic temperatures are described. Descriptions of two new transmission lines are presented, along with ac-dc difference measurements and Fast-Reversed DC (FRDC) data. Future plans for this project are also discussed.
