Optimisation of the CLIC positron capture LINAC taking into account Beam Loading effects
/ Mesbah, Nafiseh (CERN ; IPM, Tehran) ; Doebert, Steffen (CERN) ; Dayyani Kelisani, Mohsen (CERN ; IPM, Tehran) ; Latina, Andrea (CERN) ; Zhao, Yongke (CERN) ; Herrador, Javier Olivares (CERN)
This paper investigates Beam Loading in the positron source capture Linac of the Compact Linear Collider (CLIC). Beam Loading, caused by interactions between beam with accelerating cavities, leads to a reduction in the accelerating gradient, negatively affecting the Linac performance. [...]

/ Kim, S.-Y. (UNIST, Ulsan) ; Moon, K. (UNIST, Ulsan) ; Chung, M. (UNIST, Ulsan) ; Sjobak, K.N. (Oslo U.) ; Adli, E. (Oslo U.) ; Doebert, S. (CERN) ; Dayyani, M. (IPM, Tehran) ; Yoon, E.S. (UNIST, Ulsan) ; Nam, I. (Pohang Accelerator Lab.) ; Hahn, G. (Pohang Accelerator Lab.)
An active plasma lens focuses the beam in both the horizontal and vertical planes simultaneously using a magnetic field generated by a discharge current through the plasma. A beam size of 5--10 $\mu$m can be achieved within a short distance using a focusing gradient on the order of 100 T/m. [...]

Study of the Electron Beam Transfer Line for the AWAKE RUN II Experiment at CERN
/ Kim, Seong-Yeol (UNIST, Ulsan) ; Chung, Moses (UNIST, Ulsan) ; Dayyani, Mohsen (IPM, Tehran) ; Döbert, Steffen (CERN)
Proton Beam-Driven Plasma Wakefield Accelerator (PBD-PWFA) has been actively investigated at CERN within the AWAKE experiments to study the electron beam acceleration using plasma wake fields of the order of GV/m. In the AWAKE RUN 1 experiment an electron beam with an energy of 19 MeV and a bunch length of 2.2 ps rms has been used for the first demonstration of electron beam acceleration in the plasma wake fields.

The AWAKE collaboration prepares a proton driven plasma wakefield acceleration experiment using the SPS beam at CERN. A long proton bunch extracted from the SPS interacts with a high power laser and a 10 m long rubidium vapor plasma cell to create strong wakefields allowing sustained electron acceleration. [...]

Design and Beamloading-Simulations of a Pre-Bunching Cavity for the CLIC Drive Beam Injector
/ Dayyani Kelisani, Mohsen (CERN) ; Döbert, Steffen (CERN) ; Shaker, Seyd Hamed (CERN) ; Shaker, Seyd Hamed (IPM, Tehran)
The CLIC project is developing a multi-TeV center-of-mass electron-positron collider based on high-gradient, room-temperature accelerating structures and a novel two-beam RF power generation scheme. The RF power for the CLIC accelerating structures is provided by the so-called drive beam which is a low energy, high current electron beam. [...]
