Studies of capture loss of the LHC beam in the SPS

The matched voltage of the LHC beam at injection in the SPS with the nominal longitudinal parameters (bunch length 4.2 ns and emittance 0.35 eVs) is 750 kV. However, with this capture voltage, the total particle losses on the flat bottom and the beginning of the acceleration ramp can reach the 30% l...

description The matched voltage of the LHC beam at injection in the SPS with the nominal longitudinal parameters (bunch length 4.2 ns and emittance 0.35 eVs) is 750 kV. However, with this capture voltage, the total particle losses on the flat bottom and the beginning of the acceleration ramp can reach the 30% level. During the machine development (MD) sessions in 2003 some time was devoted to studies of these losses. They vary from 10% to 30% depending on the beam and machine parameters and are asymmetric in energy.
