Technical Summary

The use of squashed 3He detectors increases the resolving power in a TOF instrument. The percentage resolution is 0.0012 in back-scattering, up to 0.013 in forward scattering

Since the detectors are filled with high pressure 3He (20 bar), this keeps the efficiency high, while reducing the thickness.
