Data coding in a three-dimensional neutron diffraction experiment

The system of data re-coding of red-out from position-sensitive detectors in a three-dimensional neutron diffraction experiment is briefly described. For the realization of the system the method of coordinate conversion of each event from the ''laboratory'' system into coordinates of crystal back space is applied. Coordinate conversion occurs during data acquisition process. The system consists of three units in the CAMAC standard: time coder unit, wire numbers coding unit and re-coding unit. This system permits data re-coding without losses in data acquisition speed which extends the possibilities of the use of two-coordinate detectors for investigating neutron diffraction on monocrystals
