from the ends of these which distribute the neutron beams to the different instruments. The main guides are 20 cm high leading to three instruments on each guide. Paul Ageron and Paul Blum took charge of the construction and installation of these guides: the optics were supplied by Jobin-Yvon - Jouan-Quetin, and
the mechanical supports and vacuum chambers by Neyrpic and M.A.N. One can appreciate the important role of Paul Ageron’s work on the beam-lines to bring the Institut into reality. Now some nickel coated guides are being replaced by supermirrors guides (described in section 6.2).

Behind the yellow, orange, brown reflectometer D17 is the shielding for the detectors of the time-of-flight spectrometer described above (Fig. 3.3) The instruments are painted in vivid colours and this was started in 1972 to create a more cheerful atmosphere for the visitors.
