(a) The prototype of the 30° MWPC two-dimensional neutron detector (2 × 15°) for spatially resolved powder diffraction was built as a collaboration between the FRM II detector group, the Paul Scherrer Institute (PSI), Switzerland, and the Institut Laue–Langevin (ILL), France. In contrast with the prototype, the larger curved two-dimensional multidetector will be equipped with nine of the 15° modules. A pumping system is attached to filter the 3He + CF4 gas mixture. (b) The cathode and anode layers are arranged in sandwich mode. From the top: cathode (50 µm wires), anode (15 µm wires) and cathode (PCB strips). The curvature (ri) is 0.8 m.
