One- and Two-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 used in synchrotron radiation powder diffraction and SAXS experiments. The two‐coordinate DED‐3 detector with a multiwire proportional chamber (MWPC) is used in Laue diffraction. The latest modification of this detector, DED‐5, with a working area of 384 × 384 mm, is briefly described. The micro‐strip detector prototype MSGC‐100 has passed test synchrotron radiation experiments and the next modification (MSGC‐500), with 500 channels for high energy, is under construction. The one‐coordinate MWPC OD‐160 detector, with an angle aperture of 160° 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° section with an H‐chamber has been produced and tested on the synchrotron radiation beamline.
