The above is showing the inside of the VE, and is consisted of three
images which were taken consecutively during the plating of the
mirrors. The lamp which is shining at the left of each image is the
one used to determine the timing of the termination of the plating.
The red filaments in the middle are the filmanets of tungsten with Al
being heated. The vaporized Al were accelerated toward the glass-plate
(mirror) by the high voltage applied inside the VE.
