THE UNITED KINGDOM INFRARED TELESCOPE
ANNUAL REPORT
1995 AND 1996
6. UKIRT Upgrades
6.5. Dome Ventilation System
The Dome Ventilation System (DVS) comprises sixteen apertures spaced
around the periphery of the dome. Each is equipped with a weatherproof
roller door and sets of louvres for directing inward airflows.
The apertures were installed during 1996, beginning with a prototype as
``proof of concept'' installed in February under gruelling winter
conditions and continuing in an arduous campaign though much of the year.
The apertures now await installation of their
controls.7
The final
control system will allow remote
selection of settings of open, 1/3 closed, 2/3 closed and fully shut, for
all sixteen apertures.
