Resistive Wall Effects in CLIC Beam Delivery System
Speakers: Dominik Arominski
Status: Accepted as poster
Abstract: Resistive wall wakefields are an important issue to study for future linear colliders. Wakefields in the beam delivery system might cause severe multi-bunch effects, leading to beam quality and luminosity losses. The resistive wall effect depends on beam pipe apertures and materials, which are optimized to limit the effect's impact on the beam. In this poster, we present a study of this problem for the 350 GeV, 380 GeV and 3 TeV beam parameters and optics of the Compact Linear Collider's Beam Delivery System. First the optimization of the beam pipe apertures to limit the impact of resistive wall effect on the beam quality is shown, then the luminosity and its quality are presented. Finally, the proposed design parameters are discussed.
Synchrotron Radiation Reflections in CLIC Beam Delivery System
Speakers: Dominik Arominski
Status: Accepted as poster
Abstract: Synchrotron radiation (SR) reflection is an important issue to study for future linear colliders. SR reflection might impact the performance of the detector, through irradiation of the forward luminosity and beam quality calorimeters or the innermost layers of the vertex detector. Photons' reflections depend on the beam pipe apertures, their shape, and used materials with various surface roughness. In this poster, we present a study of this problem for the 350 GeV, 380 GeV and 3 TeV beam parameters and optics of the Compact Linear Collider's Beam Delivery System. The simulations of the SR reflections using Synrad+ software are presented and the impact on the detector is discussed.
