Formation of bremsstrahlung flow with small divergence at linac output for planet surface sounding with interplanetary space stations

The task of atmosphere structure or planet surface definition from interplanetary space stations can be decided both with use of hydrogen neutral atom beams, and flows of brake radiation. One case depth of an analysed layer is much higher in view of greater penetrating ability of quantums in comparison with neutral particles. The brake radiation is used by search of minerals with the definition from interplanetary space stations accelerators help. Until now space geophysics development restrained by radiation large angular divergence, caused target significant thickness at the accelerator. In previous works, the research results of various ways of electron flows radiation formation, driven on a cyclic of spiral orbit were stated. The opportunity of a radiation intensity increase due to electron multifold passage of the thin target under condition at the electron flow adiabatic cooling was experimentally confirmed.
