The original 1973 design specification of the CERN 50 MeV Proton Linac was for a 150 mA beam but this intensity was rarely used. Preliminary tests for the high brightness beam required for LHC...
Recent Lead Ion Storage Tests on LEAR (1997)
Bosser, Jacques, Broere, J, Carli, Christian, Chanel, M, Hill, C, Ley, R, ...
The LEAR machine is foreseen to be used as a lead ion accumulator in the injector chain for the LHC. Therefore, to test the principle of Pb54+ ion accumulation in LEAR, at 4.2 MeV/u, a number of...
Emittance preservation in the PS complex (1997)
Autin, Bruno, Giulicchi, L, Jansson, A, Lindroos, M, Lombardi, A M, Martini, M, ...
As the LHC injectors have to provide bright beams, all the potential sources of emittance blow-up must be eliminated. One such source arises from the mismatch of the betatron focusing at the...
Automated Beam Optics Correction for Emittance Preservation (1997)
Autin, Bruno, Ducas, V, Lombardi, A M, Martini, M, Wildner, E
The operation of ever more complex high energy particle accelerators requires a powerful and user friendly architecture of application programs for machine physics. Among the possible applications,...
Operational experience with the CERN hadron linacs (1997)
Charmot, H, Dutriat, C, Hill, C E, Langbein, K, Lombardi, A M, O'Neill, M, ...
The present CERN proton linac (Linac2) was commissioned in 1978 and since that date has been the primary source of protons to the CERN accelerator complex. During the past 18 years, the machine has...
Recent Results on Lead-Ion Accumulation in LEAR for the LHC (1997)
Baird, S A, Bosser, Jacques, Broere, J, Carli, Christian, Chanel, M, Hill, C, ...
To prepare dense bunches of lead ions for the LHC it has been proposed to accumulate the 4.2 MeV/u linac beam in a storage ring with electron cooling. A series of experiments is being performed in...
A new approach to space charge for Linac beam dynamics codes (1997)
Lapostolle, Pierre M, Lombardi, A M, Nath, S, Tanke, E, Valéro, S, Wangler, T P
Apart from very computer time consuming PPI routines (Particle to Particle Interaction, e.g. [1] ), all previous space charge routines require some kind of symmetry. A new routine, not requiring...
Feschenko, A V, Liiou, A V, Ostroumov, P N, Dubois, O, Haseroth, H, Hill, C, ...
A Three Dimensional Bunch Shape Monitor (3D-BSM) has been developed for the CERN Proton Linac 2. A new area for beam studies at high intensities has been opened by this detector. Bunch density...
Performance of the CERN Linac 2 with a high intensity proton RFQ (1995)
Hill, C E, Lombardi, A M, Pirkl, Werner, Tanke, E, Vretenar, Maurizio
A heavy ion linac for the CERN accelerator complex (1992)
