The
system of fast scintillation trigger (SFTS) of NUKLON equipment was developed, manufactured and
tested at JINR. The fast trigger system makes a decision to read data from all
NUCLEON systems when an "interesting" particle of cosmic rays (CR)
enters the apparatus, i.e. particle with a sufficiently high energy,
interacting with the substance of the NUCLEON carbon target. Thus, the (SFTS) is one of the most important parts of the
experimental apparatus. Structurally, the (SFTS) is 3 twin planes of scintillation detectors with
spectro shifting fiberone a photomultiplier, as a reading electronics. The
planes are located at different depths of NUCLEON recording systems, which make
it possible to trace the development of a cascade of secondary particles in (SFTS). The signal for reading the information is generated
by (SFTS) controller. In this case, the
"interesting" event from a high-energy CR particle and a developed
cascade of secondary particles is determined by the presence of intense signals
in all the (SFTS) planes, and the signal level in more
"deep" planes should increase. The reliability requirements of
multi-year operation of the (SFTS) are provided by the duplication of the
controller and the recording electronics.
