... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...

26aug00 ,2000 A temperature sensor is mounted above the IF/LO racks on the rotary floor (in the dome). ... The temperature in the rotary floor room had risen from 74 degF to 82 degF. The air conditioning in the room got the temperature back down to 74 degF at 6:00 hours. ... There is also gain downstairs. ... The current air conditioning needs about 3 hours to get the rotary floor room back to the normal temperature after a nighttime sband xmit experiment (when the air temperature is 73 degF). ...

... ARC 3.5m | Instrument Summary . ... ARCES (Echelle) : the ARC Echelle spectrograph, a high resolution (R~31,500) echelle spectrograph that observes the entire wavelength range from 3200 е to 10000 in a single image on a 2048x2048 CCD. This instrument is permanently mounted at the NA1 port. ... In addition to the facility instruments, several visitor instruments have been used at the 3.5m, and some of these are available to the ARC observing community by contacting the instrument PIs: . ...

... Before one can use a filesystem, it has to be mounted . ... Since all files in UNIX are in a single directory tree, the mount operation will make it look like the contents of the new filesystem are the contents of an existing subdirectory in some already mounted filesystem. ... mount /dev/hda3 /usr . ... When the system is booted, before the /usr љ filesystem is mounted, a /var/tmp љ directory residing on the root filesystem is used instead. ...
