Intra-beam IP Feedback Studies for the 380 GeV CLIC Beam Delivery System
/ Bodenstein, Ryan (Oxford U., JAI) ; Burrows, Philip (Oxford U., JAI) ; Plassard, Fabien (CERN) ; Snuverink, Jochem (Royal Holloway, U. of London)
In its currently-envisaged initial stage, the Compact Linear Collider (CLIC) will collide beams with a 380 GeV center of mass energy. To maintain the luminosity within a few percent of the design value, beam stability at the interaction point (IP) must be controlled at the sub-nanometer level. [...]

Beam Delivery System Optimization for CLIC 380 GeV
/ Plassard, Fabien (CERN) ; Bambade, Philip (Orsay, LAL) ; Latina, Andrea (CERN) ; Marín, Eduardo (CERN) ; Schulte, Daniel (CERN) ; Tomás, Rogelio (CERN)
In the framework of the CLIC rebaselining, the Beam Delivery System (BDS) have been re-optimized for its initial stage at 380 GeV. Two BDS designs with L*=4.3 meters and L*=6 meters have been investigated. [...]

Tuning Simulations for the CLIC Traditional Beam Delivery System
/ Bodenstein, Ryan (JAI, UK) ; Burrows, Philip (JAI, UK) ; Marín, Eduardo (CERN) ; Plassard, Fabien (CERN) ; Tomás, Rogelio (CERN)
As the design of the CLIC Beam Delivery System (BDS) evolves, tuning simulations must be performed on each of the proposed lattice designs to see which system achieves the highest luminosity in the most realistic manner. This work will focus on the tuning simulations performed on the so-called Traditional lattice design for the center-of-mass energy of 3 TeV. [...]

Two-beam Tuning in the CLIC BDS
/ Snuverink, Jochem (Oxford U., JAI) ; Bodenstein, Ryan (Oxford U., JAI) ; Tomás, Rogelio (CERN)
Beam tuning in the beam delivery system (BDS) is one of the major challenges for the future linear colliders. In those colliders, due to fast detuning of the final focus optics both beamlines will need to be tuned simultaneously. [...]

Tuning-Based Design Optimization of CLIC Final Focus System at 3 TeV
/ Plassard, Fabien (CERN) ; Bambade, Philip (Orsay, LAL) ; Latina, Andrea (CERN) ; Marín, Eduardo (CERN) ; Schulte, Daniel (CERN) ; Tomás, Rogelio (CERN)
The tuning aims to mitigate static imperfections of the Final Focus System (FFS) for emittance preservation at the Interaction Point (IP). A simulation campaign on the nominal CLIC FFS at 3 TeV have shown the need of rethink the design in order to ease the tuning of the machine. [...]

Beam Delivery Simulation: BDSIM - Automatic Geant4 Models of Accelerators
/ Nevay, Laurence (Oxford U., JAI) ; Boogert, Stewart (Oxford U., JAI) ; Deacon, Lawrence (Oxford U., JAI) ; Garcia, Hector (CERN ; Oxford U., JAI) ; Gibson, Stephen (Oxford U., JAI) ; Kwee-Hinzmann, Regina (Oxford U., JAI) ; Shields, William (Oxford U., JAI) ; Snuverink, Jochem (Oxford U., JAI)
Beam Delivery Simulation (BDSIM) is a program that uses a suite of high energy physics software including Geant4, CLHEP & ROOT, that seamlessly tracks particles through accelerators and detectors utilising the full range of particles and physics processes from Geant4. BDSIM has been used to simulate linear colliders such as the International Linear Collider (ILC) and more recently, circular colliders such as the Large Hadron Collider (LHC). [...]

Progress in Ultra-Low β* Study at ATF2

A nanometer beam size in the interaction point (IP) is required in case of future linear colliders for achieving the desired rate of particle collisions. KEK Accelerator Test Facility (ATF2), a scaled down implementation of the beam delivery system (BDS), serves for investigating the limits of electron beam focusing at the interaction point. [...]

CLIC Tuning Performance Under Realistic Error Conditions
/ Marín, Eduardo (CERN) ; Latina, Andrea (CERN) ; Plassard, Fabien (CERN) ; Schulte, Daniel (CERN) ; Tomás, Rogelio (CERN)
In this paper we present the latest results regarding the tuning study of the baseline design of the CLIC Final Focus System. In previous studies, 90% of the machines reach 90% of the nominal luminosity, when considering beam position monitor errors and transverse misalignments of magnets for a single beam case. [...]
