Electronic-mechanical device for tested samples control in neutron beams

Electronic-mechanical device (EMD) used for studying neutron interaction with nuclei at the Y-240 isothronous cyclotron according to the type ''with a sample-without a sample'' is described. EMD with electric motor realizes transposition of six samples and establishes duration of separate exposures (1.5 and 10 min) and a number of exposures (from 1 up to 999) before each measuring cycle. EMD automatically interlocks inputs of translation and accumulating spectrometer systems at the end of each exposure, accomplishes sample transposition, switches over data storage device memory extents, and performes a start-up of the subsequent expsoure
