DEVICE FOR MEASURING CORRELATIONS IN NEUTRON DECAY Russian patent published in 2008 - IPC G01T3/00 

FIELD: experimental nuclear physics, in particular, engineering of devices for magnetic spectrometry of charged particles and for studying neutron decay.

SUBSTANCE: device for measuring correlations in neutron decay contains a winding of electric magnet, a vacuum chamber and detectors for registration of electrons or protons, emitted during decay of neutrons, a central unit, made in form of vertical rod which carries winding mounting elements, cooling tubs and heat screens; the winding of the electric magnet is made in form of a set of identical vertical circular windings, the circular windings contain channels for injection of liquid helium and are connected to circular forcing collector which is positioned below the anchor ring of windings; the vacuum chamber is made in form of two vertical hemispheres, which are hermetically connected by means of flanges to vertical circular cowling with the central unit rod fastened in it diametrically, it envelopes the windings of the electric magnet with elements of the cryogenic system and contains windows for connecting horizontal vacuumized neutron conductor; detectors of protons and electrons are composed of three independent sections, where first and second sections of detectors are made in form of two flat mosaic sets of scintillators, positioned above and below the beam of neutrons close to the point of its closest proximity to the vertical axis of the system, and third section of detectors is made in form of a sandwich of two combined identical vertical plates of scintillators with an intermediate deflecting screen, positioned on the other side of the vertical rod relatively to first two sections of detectors and perpendicular to the axis of the neutron beam.

EFFECT: expanded functional capabilities when studying correlations in decay of a polarized neutron, increased manufacturability and compactness of device.
