ONE-COORDINATE AND 2-COORDINATE DETECTORS IN BINP

One- and two-coordinate detectors with proportional chambers developed at the Budker Institute of Nuclear Physics (BINP) are presented. The parallax-free 10 MHz one-coordinate OD-3.1 and OD-3.2 detectors are us ed in synchrotron radiation powder diffraction and SAXS experiments. T he two-coordinate DED-3 detector with a multiwire proportional chamber (MWPC) is used in Laue diffraction. The latest modification of this d etector, DED-5, with a working area of 384 x 384 mm, is briefly descri bed. The micro-strip detector prototype MSGC-100 has passed test synch rotron radiation experiments and the next modification (MSGC-500), wit h 500 channels for high energy, is under construction. The one-coordin ate MWPC OD-160 detector, with an angle aperture of 160 degrees and a count rate of 3.3 GHz, is under construction. It will be used for high -resolution powder diffraction. Two types of gas chamber will be used: L for low energies (5-30 keV) and H for high energies (30-70 keV). A 16 degrees section with an H-chamber has been produced and tested on t he synchrotron radiation beamline.
