Crystal for slow extraction loss-reduction of the SPS electrostatic septum
The use of a bent crystal was investigated in order to reduce the losses at the CERN Super Proton Synchrotron (SPS) electrostatic septum (ZS) during the slow extraction of 400 GeV/c protons toward the North Area. The crystal, installed a few meters upstream of the ZS, bends protons that would otherw...

| description | The use of a bent crystal was investigated in order to reduce the losses at the CERN Super Proton Synchrotron (SPS) electrostatic septum (ZS) during the slow extraction of 400 GeV/c protons toward the North Area. The crystal, installed a few meters upstream of the ZS, bends protons that would otherwise impinge on the ZS wires. Since particle deflection with good efficiency is achieved only when the crystal lattice is aligned within 10 μrad to the trajectory of the incoming particles (at p = 400 GeV/c), a compact goniometer was built to allow the correct angular alignment of the crystal with a precision of a few μrad. In this paper, we report on the crystal features measured during a dedicated beam test by the UA9 experimental installation in the CERN H8 beam line. Details of the goniometer and its installation are also reported. The first results achieved during dedicated Machine Development (MD) sessions are finally presented. |
