New one and two-coordinate detectors in SSRC

The one and two coordinate detectors using proportional chambers developed in the Budker Institute of Nuclear Physics (BINP) are presented. The parallax-free 10 MHz one-coordinate detectors OD-3.1 and OD-3 are used in the synchrotron radiation powder diffraction and SAXS experiments. The two-coordinate detector DED-3 with MWPC (multiwire proportional chamber) are used in Laue diffraction. The last modification of this detector DED-5 with working area 384*384 mm is briefly described here. The micro strip detector prototype MSGC-100 has passed test experiments on SR and next modification MSGC-500 with 500 channels for high energy is under construction. The one coordinate MWPC detector 1D-160 with angle aperture 160 degree and count rate 3.3 GHz is under construction. It will be used for high resolution powder diffraction. The two type of gas chamber will be used - "L" for "low" energy range 5-30 keV and other "H" for "high" energy 30-70 keV. At this moment the 16 degree section with "H" chamber was produced and tested at the SR beam line.
