LSST Mirror Passes High Fire
2 Abril 2008
The LSST primary/tertiary mirror experienced a successful “high fire” over the weekend of March 28-29, reaching a peak temperature of approximately 1165°C (2125°F). The LSST mirror will now anneal and cool gradually to room temperature over the next 100 days in the slowly rotating oven at the UA Steward Observatory Mirror Lab, and will be removed in mid-August to begin grinding and polishing.
