Jirgal, G. H.; and others – Amer J Phys, 1969
Describes the construction and use of an inexpensive, vacuum furnace designed to produce F-centers in alkali halide crystals by additive coloration. The method described avoids corrosion or contamination during the coloration process. Examination of the resultant crystals is discussed and several experiments using additively colored crystals are…

Berg, T. G. Owe; Gaulkler, T. A. – Amer J Phys, 1969
Describes the construction and use of an apparatus for the free suspension of charged particles and droplets in the range 5-200u and for their study with respect to charge and mass and their variations with time in various gaseous environments. High-speed photography is used to determine the motion of particles. (LC)
