PURPOSE: A method of manufacture of ceramic ARC tubes is provided to increase the production capacity of the sintering method by combining a plurality of sintering fixtures in a stacked arrangement and reduce defects associated with misalignment of the end caps by relying on gravity. CONSTITUTION: A method of manufacturing a ceramic ARC chamber(420) includes a process of providing a sintering tray including a plurality of bores(422). The bores(422) have a first diameter upper section(424) and a second narrower diameter lower section(426). A plurality of ceramic end caps(212) having a main body portion, and a leg portion(219) in the bores(422) are positioned such that the leg portion(219) passes downwardly through the narrower diameter lower section(426) and the main body portion(216) is retained within the upper section(424). Moreover, the second diameter lower section(426) acts as a shoulder supporting the end cap(210). Next, a ceramic arc tube(214) is positioned within the first diameter upper section(424) and mated with the ceramic end cap(212). A second end cap(210) is mated to a second upper open end of the ceramic arc tube(214) to form an arc tube preform(420). The arc tube preforms(420) are then sintered to join the components via controlled shrinkage.
