Abstract
A self-aligning fixture for use in a high temperature top-loading furnance includes multiple stacked trays to optimize load placement and capacity and to minimize fixture heat absorption. The fixture is manipulated by a handling tool to insert, position, and withdraw the fixture without obscuring the chamber and includes self-aligning blackbody radiators insertable by a handling tool into the optical path of an optical pyrometer and onto a selected tray for temperature monitoring of the load therein. A calibration blackbody radiator allows independent pyrometer verification of an inserted thermocouple.
