Abstract :
Various types of mountings are described for quartz oscillator crystals having frequencies in the vicinity of one million cycles per second. For low power work a spaced upper electrode is recommended, mounted in a neon-filled tube. For radiating up to 50 watts from the crystal-controlled tube, a similar mounting placed in a copper-based tube is advised. This latter tube can be cooled by immersion in an oil bath. Accurate temperature control of the oil bath keeps the radio frequency within narrow limits.
