Luminosity-driven channeling extraction has been observed for the first time in a 900 GeV study at the Fermilab Tevatron. This experiment, Fermilab E853, demonstrated that useful TeV level beams can be extracted from a superconducting accelerator dur

The first experimental run of the physical setup PROZA with 70 GeV protons extracted by a bent crystal took place at the end of the 1980s. The experimental results of the proton extraction in the common mode with extraction of secondaries are present

The results of an investigation of the electrode-quartz interface by use of the RMA method for Au, Ag, and Cu electrodes are presented. Possible reasons for the disturbed equilibrium state of the double layer are considered, e.g., under high levels o

In 1987, during investigation the polarization effects on the experimental setup PROZA, an indication on a possible discovery of an unknown phenomenon, the scaling asymmetry, was obtained. The interval of the investigated energies was not large: from

The influence of a thin target on the bent crystal extraction efficiency at 70 GeV is discovered in the IHEP accelerator. This effect was also confirmed at 50 GeV. It is supposed that the effect can be used for beam extraction from higher energy acce
