Measurements of heavy ion beam losses from collimation (2009)
Bruce, R., Assmann, R. W., Bellodi, G., Bracco, C., Braun, H. H., Gilardoni, S., ...
The collimation efficiency for Pb ion beams in the LHC is predicted to be lower than requirements. Nuclear fragmentation and electromagnetic dissociation in the primary collimators create fragments...
A Storage Ring based Option for the LHeC (2008)
Willeke, F, Bordry, Frederick, Braun, H H, Brüning, Oliver Simon, Burkhardt, H, Chattopadhyay, S, ...
The LHeC aims at the generation of hadron-lepton collisions with center of mass energies in the TeV scale and luminosities of the order of $10^{32}-10^{33} cm^{-2} sec^{-1}$ by taking advantage of...
Linac-LHC EP Collider Options (2008)
Zimmermann, F, Aksahal, H, Bordry, Frederick, Braun, H H, Brüning, Oliver Simon, Çiftçi, A K, ...
We describe various parameter scenarios for a ring-linac ep collider based on LHC and an independent electron linac. Luminosities between $10^{31}$ and $10^{33} cm^{-2}s^{-1}$ can be achieved with a...
Parameter Scan for the CLIC Damping Rings (2008)
Papaphilippou, Y, Braun, H H, Korostelev, M
Triggered by the RF frequency reduction of the CLIC main linac cavities, the damping ring parameters had to be reevaluated and the rings performance adapted to the new luminosity requirements. In...
Optimizing the CLIC Beam Delivery System (2008)
Tomás, R, Braun, H H, Jørgensen, M, Schulte, D
The optimization of the new CLIC Final Focus System (FFS) with L*=3.5m is presented for a collection of CLIC beam parameters. The final performance is computed for the full Beam Delivery System...
Measurements of Heavy Ion Beam Losses from Collimation (2008)
Bruce, R, Assmann, Ralph Wolfgang, Bellodi, G, Bracco, C, Braun, H H, Gilardoni, S, ...
The collimation efficiency for $^{208}Pb^{82+}$ ion beams in the LHC is predicted to be lower than requirements. Nuclear fragmentation and electromagnetic dissociation in the primary collimators...
Optimisation of a Beam Transfer FODO Line (2008)
With in view the design of the CLIC long transfer lines, we develop a formal approach for the optimisation of a straight FODO line. Optimum phase advance and cell length depending on beam parameters...
Instrumentation for Longitudinal Beam Gymnastics in FEL's and at the CLIC Test Facility 3 (2007)
Lefèvre, T, Braun, H H, Bravin, E, Burger, S, Corsini, R, Döbert, S, ...
Built at CERN by an international collaboration, the CLIC Test Facility 3 (CTF3) aims at demonstrating the feasibility of a high luminosity 3 TeV e+-e- collider by the year 2010. One of the main...
Segmented Beam Dump for Time Resolved Spectrometry on a High Current Electron Beam (2007)
Lefèvre, T, Dutriat, C, Bravin, E, Braun, H H
In the CLIC Test Facility 3 (CTF3), the strong coupling between the beam and the accelerating cavities induces transient effects such that the head of the pulse is accelerated twice as much as the...
Towards a Multi TeV Linear Collider: Drive Beam Generation With CTF3 (2007)
The 3 TeV compact linear collider, CLIC, foresees an RF source based on a high current drive beam running parallel with the main linac. To generate this drive beam of very high instantaneous power a...
Time resolved spectrometry on the CLIC Test Facility 3 (2006)
Lefèvre, T, Bal, C, Braun, H H, Bravin, E, Burger, S, Corsini, R, ...
The high charge (>6ìC) electron beam produced in the CLIC Test Facility 3 (CTF3) is accelerated in fully beam loaded cavities. To be able to measure the resulting strong transient effects, the time...
Coherent Synchrotron Radiation Measurements in the CLIC Test Facility (CTF II) (2000)
Braun, H. H., Corsini, R., Groening, L., Zhou, F., Kabel, A., Raubenheimer, T., ...
Bunches of high charge (up to 10 nC) are compressed in length in the CTF II magnetic chicane to less than 0.2 mm rms. The short bunches radiate coherently in the chicane magnetic field, and the...
