Extraction of 70 GeV Proton Beam to RAMPEX with a bent Si Crystal
Protvino, 2000.-p.14, figs.9, refs.:9.


For measurements in the experiment RAMPEX with the 70~GeV proton beam, extracted directly from the accelerator U-70 with a bent Si crystal, it is necessary to have stable proton beam on the polarized target of the following parametres: the beam intensity of $5 \times 10^6$ p/c and the beam size, characterized by values $\Delta x = \pm 5$~mm, $\Delta y = \pm 7$~mm with $\pm 2{,}5$~mrad angular divergences. The experimental data on investigations and the stable beam shaping with the existing bent Si crystal were carried out.
