9C25.10high vacuum systemAJP 36(3),234Design of a high vacuum system suitable for lecture demonstration.
9C25.10movable vacuum system16-6.1Pictures of a movable vacuum system good to high vacuum. Construction Details in the Appendix, p 610.
9C25.10vacuum systemA-57Construction of a portable high vacuum system.
9C25.15vacuum loreAJP 32(7),viLet in only dry gas or heat traps to 100 C to reduce water contamination.
9C25.15liquid nitrogen cold trapAJP 37(1),109Mount a styrofoam bucket on top of a minimum sized reentrant can-type trap.
9C25.20Bayard-Alpert type ionization gaugeAJP 30(8),vA single device contains a titanium vapor pump that consists of a titanium filament depositing a film on the wall to act as a getter, and a Bayard-Alpert type ionization gauge.
9C25.20power supply for Penning vacuum gageAJP 32(6),504Schematic diagram for a Penning vacuum gauge power supply.
9C25.20homemade high vacuum techniquesAJP 32(6),483Make experimental vacuum tubes with solder glass, mass produced headers, and multiple gettering.
9C25.25thin films of dielectrics and metalsAJP 28(7),654Directions for making a transparent aluminum oxide film on a front surface mirror. The interference colors of the mirror and glass sides are complementary. A parallelogram frame permits demonstrating the change of color with angle of incidence. More.
