|
 |
By William J. Wheeler, University of Wisconsin-Madison. published in FUSION, Journal of the American Scientific Glassblowers Society, 1971. This paper describes construction details of an 18" diameter, 10 foot-long Pyrex tube and a 21 tube heat exchanger. The 18" tube was used to electrically insulate a microwave discharge in a 24" diameter, 12 foot-long stainless steel chamber. The heat exchanger allowed the microwave chamber to be operated at liquid nitrogen temperature. An internal chuck glassblowing lathe to hold sections of 18" diameter tubing was constructed for this project. Html format. |
