instrument D22 at the ILL, i.e. it should in particular have a spatial resolution of 7.5 x 7.5 mm, an active area of 96 x96 cm, a sensitivity of 75% for neutrons of 5Å wavelength, and a similar quiet count

in stroboscopic mode. Today, up to 256 complete diagrams or slices can be recorded, with a minimum active counting time window (open gate ) of 1 µs inside each slice of at least 30 µs (so a maximum slice
