1200°C High Vacuum Furnace

Empty pressure: < 8 ´10-7 torr

Used to degas hydrogen from niobium cavities at 600 - 800°C to avoid Q-disease (hydride precipitation) during slow cooldown through the 100 K region.

Used occasionally for purifying bulk niobium via solid state gettering at 1250°C with titanium

(Shown with 700 MHz test cavity in hot zone)
