In present paper we propose application of partially depleted semiconductor detectors for measurements of ionization loss of ultra-relativistic charged particle as a function of its path inside the semiconductor. Results of preliminary measurements of most probable ionization loss in Si of electrons emitted from 207Bi radioactive source as a function of the power supply voltage of Si detector are presented. Prospects for application of such detectors for research of evolution of electromagnetic field of the particle which crosses a boundary of a solid target [2] are discussed. The paper became possible partially due to grant SFFR #58/17. References 1. E. Kowalski. Nuclear electronics, Springer-Verlag, Berlin, New York, 1970. 2. N.F. Shul’ga, S.V. Trofymenko Nucl. Instrum.
