ABSTRACT
A new approach to the measurement of high energy cosmic ray nuclei (E>10[sup 11] eV) is proposed. The method is based on measuring the primary particle energy by determining the angular distribution of secondaries produced in a target layer. The proposed technique can be used over a wide range of energies (10[sup 11]–10[sup 16] eV) and gives an energy resolution of 60% or better. This approach is being utilized to design a new advanced instrument (KLEM) for future space station and satellite cosmic ray experiments. Due to its light weight and large aperture the newly developed instrument will allow a dramatically increased exposure factor and will enable the directly measured energy range in cosmic ray research to be extended up to and beyond 10[sup 16] eV. A reduced scale version of this new instrument (project TUS-M) has already been accepted for exposure in the Russian Segment of the International Space Station. The essence of the TUS-M project is to test and confirm the new technique under flight conditions. During a one-year test exposure TUS-M will be able to measure the energy spectra of primary particles up to 10[sup 14] eV. The full scale instrument, with a three-year exposure has the capacity to address the “knee” problem with a data base including at least 25 particles with E>10[sup 16] eV. © 2000 American Institute of Physics.

There is so far no indication of the GZK cutoff in the energy spectrum at 5x 10[sup 19] eV. This conclusion is not firm for lack of statistics. A cutoff would be expected if the sources of...
