The participants were from Kavli IPMU, collaborators having the\u00a0responsibility for the Spectrograph, and Hawaii Observatory.<\/p>\n<p>The spectrographs are put on the fourth floor in the dome building of \u00a0Subaru telescope. The floor will have a huge clean room with the weight\u00a0of 15 ton (33000 lb) for four spectrographs. The clean room is designed to have a crane for building up and maintaining the observational<br \/>\ninstruments, and an air control system for keeping the stability of the instruments.<\/p>\n<p>There are various topics for design of the floor, not only the details of the clean room. For example, we need to arrange a bunch of cables and pipes in order to control mechanics, to cool down the cryogenic camera\u00a0unit, and to operate the detectors. We also need to use safely and maintain easily the electric power as high as 30kVA at maximum, which corresponds to 15 standard homes. Because most of these equipment are newly prepared as well as the PFS spectrographs themselves, we should determine in details how to safely and steadily transfer all parts up to the fourth floor, and to\u00a0build up the room and instruments. We engaged in a vigorous debate about various topics like these for two days.<\/p>\n<p><a style=\"line-height: 1.714285714; font-size: 1rem;\" href=\"https:\/\/pfs.naoj.org\/blog\/wp-content\/uploads\/2015\/08\/IR4_design.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-59\" src=\"https:\/\/pfs.naoj.org\/blog\/wp-content\/uploads\/2015\/08\/IR4_design-300x228.png\" alt=\"IR4_design\" width=\"300\" height=\"228\" srcset=\"https:\/\/pfs.naoj.org\/blog\/wp-content\/uploads\/2015\/08\/IR4_design-300x228.png 300w, https:\/\/pfs.naoj.org\/blog\/wp-content\/uploads\/2015\/08\/IR4_design-624x474.png 624w, https:\/\/pfs.naoj.org\/blog\/wp-content\/uploads\/2015\/08\/IR4_design.png 967w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><span style=\"line-height: 1.714285714; font-size: 1rem;\">\u00a0(design of the floors)<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A review meeting for the Clean Room holding the spectrographs was held\u00a0on 19 and 20 August at Hawaii Observatory, National Astronomical\u00a0Observatory of Japan.
