The Beamlines
All thirty of the ESRF public beamlines have been operational since 1999. Two of these possess two end-stations, so there are thirty two end-stations in total, which can be run independently. An additional sixteen beamline branches, situated on bending magnets, are devoted to Collaborating Research Groups (CRG). Eleven of the CRG beamlines are now in operation (including GRAAL), the others are being commissioned or under construction. Figure 141 shows the location of the beamlines in the experimental hall; a list of the public beamlines is presented in Table 7; and a list of the CRG beamlines in Table 8.
Following management proposals, in agreement with Council's decision of June 2000, the Powder Diffraction beamline has been transferred from a bending magnet, BM16, to an insertion device, ID31. Similarly, BM14, the MAD beamline, was transferred to ID29 during 2000-2001. BM16 will become a Spanish CRG line with full MAD capability, and BM14 is now a British CRG, also dedicated to MAD studies in structural biology.
Additionally, there is an industrial beamline, ID27, which has been constructed for impurity analysis on silicon wafers. This line has capacity for further expansion to other fields of industrial interest, and different possibilities are currently under consideration.
Finally, a new beamline complex dedicated to protein crystallography is under construction on ID23 as part of the Partnership for Structural Biology (PSB).
