Presentation Transcript

  1. Abridged to only those lines which are still POSSIBLE (2007) • These 2 (or 4) lines would enable to distinguish • in a quantative way between • rotation of the bridge • bending of the bridge • deformation or C-Frames • High precision in Y and Z (~ 5 microns) because there is lots of space for lenses with large diameter • Possible : • cable trays in place, easy access, • 6 spare channels in RasMux, 7 spare holes in patch pannels, spare cables, standard masks, spare CCDs

  2. Upper 6 points need RASNIK alignment (x,y,z) Points used by RASNIK short lines points mark positions of CCD with lenses fixed together to rails or pillars (not to C-frames) 6 lower points insignificant movements – no RASNIK

  3. MASK 2 (or 4) lines on top of the bridge LENS CCD (out of scale)

  4. Horizontal lines above upper rails(on top of the bridge) 2 (or 4)lines above rails 2 CCD, 2 masks, 2 (or 4)lenses z x ~ 8 cm LENES 10cm up 10.5° MASK CCD 1407 10cm up MASK CCD 7600
