General Electric SRT-1 X-ray Tube |

A General Electric SRT-1 therapy tube with a one inch diameter beryllium window.
The "T" in the tube designation indicates that it was used for
therapy while the "1" indicates that it was a fine focus tube.
More specifically, this number indicates the approximate diameter of the
projected focal spot in mm. I believe that the "SR" stands for
self-rectifying. This particular tube belonged to M. J. Gross who worked with Dr. Coolidge at General Electric in Schenectady N.Y. Gross later became Vice President of the GE X-ray Company. During the 1930s and 1940s, Gross and Zed Attlee formed the core of Coolidge's research and design team. Size: approximately 7 1/2" long, 3" diameter Kindly donated by Linda Sinrod in memory of Malvern J Gross |
