A setup of two bent crystals and a fixed target in the CERN Large Hadron Collider (LHC) could enable study magnetic (MDM) electric (EDM) dipole moments short-lived charm baryons with unprecedented accuracy. At core experiment is crystal which particles interest, such as $\Lambda_c^+$ $\Xi_c^+$ particles, can be confined between crystalline planes, inducing deflection that enforces spin precession measurable by detectors. The requires inside LHC vacuum to create charmed baryons. first serves...
Quadrupole fringe fields in the final focus system can be a source of aberrations interaction point transverse beam sizes. This paper investigates field impact on size ATF2, ILC, and CLIC lattices linear non-linear regimes. The effects are studied by replacing hard-edge quadrupolar more realistic gradient fall-off. To address nonlinear effects, represented as high order kicks added to both sides magnets. It will shown that easily cured tuning quadrupole strengths. On other hand, mitigation...
Ground motion is a severe problem for many particle accelerators, since it excites beam oscillations, which decrease the quality and create beam-beam offset (at colliders). Orbit feedback systems can only compensate ground effects at frequencies significantly smaller than repetition rate. In linear colliders, where rate low, additional counter measures have to be put in place. For this reason, mitigation method based on feed-forward control presented paper. It has several advantages compared...
A nanometer beam size at the interaction point (IP) is required for future linear colliders to achieve desired rate of particle collisions. KEK Accelerator Test Facility 2 (ATF2), a scaled down implementation collider delivery system, serves demonstrating feasibility final focus system (FFS). An unprecedented low vertical IP about 40 nm has been already measured in ATF2 using optics with nominal ${\ensuremath{\beta}}_{y}^{*}$. In our study we decrease ${\ensuremath{\beta}}_{y}^{*}$ value...
For the commissioning and operation of modern particle accelerators, automated error detection diagnostics methods are becoming increasingly important. In this paper, we present two such methods, which capable localising sources beam offset jitter with a combination correlation studies so called degree freedom plots. The were applied to ATF2 line at KEK, where one major goals is reduction jitter. Results localisation shown in paper. A big advantage presented method its high...
Abstract In addition to the physics program with proton beams, Large Hadron Collider (LHC) at CERN also provides collisions of fully-stripped Pb beams for about one month per year. When colliding nuclei, electromagnetic interactions are dominating processes because intense Coulomb field produced by ions. These ’ultra-peripheral’ give rise ions a changed magnetic rigidity. This causes losses in machine that can impose limits on luminosity. Among them, bound-free pair production (BFPP)...
Abstract For about one month per operational year, the Large Hadron Collider (LHC) at CERN works as a heavy-ion collider. Four one-month Pb-Pb runs have been executed so far well two p-Pb runs. The LHC programme is scheduled to continue in future, featuring increased luminosity and beam energy. Beam losses caused by ions fragmenting collision process risk introducing performance limitations. Losses occur immediately downstream of points other locations ring, through multi-turn dynamics...
The high luminosity requirement for a future linear collider sets demanding limit on the beam quality at Interaction Point (IP). One potential source of loss is motion ground itself. resulting misalignments quadrupole magnets cause distortions to orbit and hence an increase in emittance. This paper describes technique compensating this distortion by using seismometers monitor misalignment real-time. first demonstration was achieved Accelerator Test Facility (ATF) KEK Japan. feed-forward...
The CERN accelerator complex is undergoing an upgrade in order to meet the requirements of High-Luminosity Large Hadron Collider (HL-LHC). One key needs increase intensity beams injected into LHC from current $1.15\ifmmode\times\else\texttimes\fi{}{10}^{11}$ $2.3\ifmmode\times\else\texttimes\fi{}{10}^{11}\text{ }\text{ }{\mathrm{p}}^{+}/\mathrm{bunch}$. This requires a beam at injection Super Proton Synchrotron (SPS), last injector before LHC, as high...
The two dominant radiotherapy methods are either simplified in terms of beam generation and handling, which compromises the energy deposition curve tissues (photon therapy), or require extensive accelerator facilities complex delivery systems to provide a favorable shape (hadron therapy). advantages both these methods, such as low cost apparatus, ease generation, suitable tissues, can potentially be achieved by using very high-energy electron (beam order few hundreds MeV) focused on area...

The high luminosity requirement for a future linear collider sets demanding limit on the beam quality at Interation Point (IP). Even natural motion of ground could misalign quadrupole magnets to such an extent that resulting dipole kicks would require compensation. novel technique described in this paper uses seismometers measure positions real time and kicker counteract effect their misalignment. prototype system deployed Accelerator Test Facility (ATF) KEK Japan has already demonstrated...
