METHODS FOR PRECISION TEMPERATURE CONTROL
Abstract
The investigation of methods and devices by which the temperature of a single quartz crystal blank can be maintained at 85 C in environmental temperatures ranging from +80 C to -55 C is continuing Vacuum testing was begun on 5 partially silvered Pyrex dewars which were for use as the insulation of 500-mw ovens. An initial heat leak test of one of these was made in conjunction with a stainless steel dewar to determine whether such a double dewar had promise for use as the insulation for the less-than500-mw ovens. In addition, 3 different types of insulation systems for use with 50-mw crystal ovens were c nstructed for vacuum-life testing. The system required to suspend the core in two of these insulation systems was modified to reduce heat leak through it. (Author)
