Work on construction of the full size cooled wall cloud simulation chamber has been pursued in three main areas. The mechanical construction has begun the assembly of the small Proto II chamber and started machining of the major components of the large Romulus chamber. The study of the temperature uniformity over the surface of the inner wall plates was completed. The design problem with the primary chamber sealing gaskets was solved. The optical table and tower for the Romulus chamber were purchased and set up for testing. Also a preliminary design for an actively cooled window port was developed. Construction of the switching power supplies, and development of the control systems for the thermoelectric modules used for wall temperature control was initiated. Drift problems with the transistor thermometers were traced to changes in manufacturers procedures and corrective measures were taken to solve the problem. Author
