     A team of MEPhI staff headed by E.V. Atkin together with the SINP MSU has developed a new multichannel integrated microcircuit for reading silicon sensor signals for the microcalorimeter of scientific equipment of NUCLEON experiment. The microcircuit was named after the NUCLEON experiment using it, its basis is 32 channels of charge-sensitive amplifiers with a record dynamic range up to 100 pC. This makes it possible to use NUCLEON chips in an ionization electromagnetic calorimeter of NUCLEON SC, where the expected multiplicity of secondary particles can reach 104 per channel of registration. In addition, NUCLEON chip is characterized by low power consumption -2 mW / channel, which was also a fundamental requirement for creating electronics for space experiment. 
        In the process of creating the NUCLEON SC, more than 50 microcircuits were manufactured and installed in the electronics of a microcalorimeter. At present, the NUCLEON microcalorimeter is fully equipped and operates as a part of NUCLEON SC.
