“…Long-duration balloon experiments like ATIC [1], TRACER [2], CREAM [3] allowed to determine fine structure of cosmic rays spectra up to 10 14 eV. With huge interest new data on protons, nuclei and electrons spectra obtained by space experiments PAMELA [4], AMS02 [5], ATIC [6], FermiLAT [7], NUCLEON [8], CALET [9], DAMPE [10] was accepted and interpreted. Above-mentioned experiments won't be able to solve completely these tasks.…”

The main goal of the High-Energy Ray Observatory (HERO) mission is to perform direct measurements of very high energy cosmic ray. Measurements will concern the following scientific goals: detailed study of charge composition of CR in knee region, studies of the energy spectra of Galactic and extragalactic CR, search for signatures of dark matter particles. HERO is planned to be launched onboard a heavy satellite. This experiment is based on the application of a wide aperture (>2π) deep (~5λ) ionization calorimeter. The effective geometrical factor of the apparatus is not less than 8-16 m 2 sr depending on the type of particles. Under the long exposure (~10 years), this mission will make it possible to precisely measure cosmic rays up to 10 17 eV. Wide Monte-Carlo simulations were performed to obtain instrument response for different species of cosmic rays, including charged particles and gammas.

“…An additional absorber layer 3.5 mm thick, placed behind the minicalorimeter in order to improve electron scattering in the inverse directions under the conditions of a fully developed shower, increases the total minicalorimeter thickness up to 12.4 X 0 . Together with the energy measuring system and the target, the thickness of the ionization calorimeter of the NUCLEON setup measures 15.3 X 0 [1,2].…”

The 32-channels ASIC with a unique dynamic range from 1 to 40000 mips, signal to noise ratio not less than 2.5 at a shaper peaking time of 2 µs and a low power consumption of 1.5 mW/channel has been designed. The transfer function of the charge sensitive amplifier (CSA), having two subranges of various gains, allowed to reach high dynamic range of the readout electronics. The subranges are automatically switched. Two ASICs were installed on a ladder construction which also contains an ADC, a microprocessor and a power supply. The ASIC and the ladder were created for the minicalorimeter of the NUCLEON experiment. The goal of the NUCLEON satellite mission is to measure the elemental (Z from 1 to 30) energy spectra of highenergy (10 11 -10 15 eV) cosmic rays. The ladder has been tested at the SPS. The ladder can also be used for other future HEP and space cosmic ray experiments.
