Title:
STREAK TUBE AND ITS PRODUCTION METHOD
Document Type and Number:
Japanese Patent JPS5996640
Kind Code:
A
Abstract:

PURPOSE: To obtain a streak tube not generating unnecessary emission by providing a bulkhead with an opening including the tube axis between a photoelectric surface and a deflection electrode, maintaining the cover of the opening at a closed position while the photoelectric surface is produced, and normally opening it to form a pass route of electrons.

CONSTITUTION: A space in a vacuum airtight container 3 containing a photoelectric surface 4, a mesh electrode 5, a focus electrode 6, and an aperture electrode 7 and a space in the container 3 containing a deflection electrode 8 and a phosphor screen 9 are divided by a bulkhead 30. An opening 13 is provided on the bulkhead 30 and a cover 14 is provided facing the opening 13. The center of the opening 13 is made to match a tube axis and its position in the tube axis direction is located at or near a crossover point 11 where a photoelectron beam is focused. During a production process, the cover 14 closes the opening 13 by gravity, and antimony stored in a branch tube 18 is extracted and deposited on a photoelectric surface substrate 1. Next, an alkali metal in a branch tube 17 is evaporated and combined, and after the stabilizing treatment the process is completed. Then, the attitude of the container 3 is changed, the opening 13 is opened and the cover 14 is fixed, thus unnecessary emission can be prevented.
