| MOPRO034 | Studies on Nonlinear Post-linac Protection for CLIC | 148 |
|
||
| The post-linac energy collimation system of CLIC is designed to fulfill an essential function of protection of the Beam Delivery System (BDS) against miss-steered beams generated by failure modes in the main linac. Guaranteeing the collimator survivability in case of direct beam impact is very challenging, if we take into account the need to deal with an unprecedented transverse beam energy density per beam of the order of GJ/mm2. This translates into a high damage potential of uncontrolled beams. In this paper we present an alternative nonlinear energy collimation system as a potential solution to guarantee the survival of the collimators. The performance and error tolerances of this system are studied by means of beam tracking simulations, and compared with those of the conventional baseline CLIC energy collimation system. | ||

| MOPRO045 | Beam Delivery Simulation: BDSIM - Development & Optimisation | 182 |
|
||
|
Funding: Research supported by FP7 HiLumi LHC - grant agreement 284404. Beam Delivery Simulation (BDSIM) is a Geant4 and C++ based particle tracking code that seamlessly tracks particles through accelerators and detectors, including the full range of particle interaction physics processes from Geant4. BDSIM has been successfully used to model beam loss and background conditions for many current and future linear accelerators such as the Accelerator Test Facility 2 (ATF2) and the International Linear Collider (ILC). Current developments extend its application for use with storage rings, in particular for the Large Hadron Collider (LHC) and the High Luminosity upgrade project (HL-LHC). This paper presents the latest results from using BDSIM to model the LHC as well as the developments underway to improve performance. |

| TUPME008 | Status of the CLIC-UK R&D Programme on Design of Key Systems for the Compact Linear Collider | 1354 |
|
||
| Six UK institutes are engaged in a collaborative R&D programme with CERN aimed at demonstrating key aspects of technology feasibility for the Compact Linear Collider (CLIC). We give an overview and status of the R&D being done on: 1) Drive-beam components: quadrupole magnets and the beam phase feed-forward prototype. 2) Beam instrumentation: stripline and cavity beam position monitors, an electro-optical longitudinal bunch profile monitor, and laserwire and diffraction and transition radiation monitors for transverse beam-size determination. 3) Beam delivery system and machine-detector interface design, including beam feedback/control systems and crab cavity design and control. 4) RF structure design. In each case, where applicable, we report on the status of prototype systems and performance tests with beam at the CTF3, ATF2 and CesrTA test facilities, including plans for future experiments. | ||

| WEPME083 | VELA: A New Accelerator Technology Development Platform for Industry | 2471 |
|
||
| The Versatile Electron Linear Accelerator (VELA) facility will provide enabling infrastructures targeted at the development and testing of novel and compact accelerator technologies, specifically through partnership with industry and aimed at addressing applications in medicine, health, security, energy and industrial processing. The facility has now been commissioned at Daresbury Laboratory and the facility is now being actively utilised by industrial groups who are able to take advantage of the variable electron beam parameters available on VELA to either demonstrate new techniques and/or processes or otherwise develop new technologies for future commercial realisation. Examples of which to be presented include; demonstration of a new cargo scanning process, characterisation of novel, high performance beam position monitors, as well as other technology development applications. | ||

| THPME178 | Status of the CLIC/CTF Beam Instrumentation R&D | 3690 |
|
||
| The Compact Linear Collider (CLIC) is an e+/e− collider based on the two-beam acceleration principle, proposed to support precision high-energy physics experiments in the energy range 0.5-3 TeV. To achieve a high luminosity of up to 6e34cm-2s−1, the transport and preservation of a low emittance beam is mandatory. A large number and great variety of beam diagnostics instruments is foreseen to verify and guarantee the required beam quality. We present the status of the beam diagnostics developments and experimental results accomplished at the CLIC Test Facility (CTF), including new ideas for simplification and cost reduction of the CLIC beam instrumentation. | ||
