Box for X-shooter cold optics

Submitter: Hiddo Hanenburg
Description: Currently the new milling machine (see archive 8 Jan 2007) is making a lot of aluminium 6061 chips to manufacture the box for the cold optics of X-shooter. Prisms, grating, mirrors and lenses for the ESO spectrograph will be mounted outside and inside this box and all has to be cooled to 105K. The photos show the progress of the milling process reducing the original weight of 400 kg to about 50 kg. If you are interested please feel free to drop by Hendry Hof in the workshop. But don't forget your umbrella if the machine is running.
