SAMbuCa: Sensors Acquisition and Motion Control Framework at CERN
/ Masi, Alessandro (CERN) ; Andreassen, Odd (CERN) ; Arruat, Michel (CERN) ; Danzeca, Salvatore (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN) ; Fargier, Sylvain (CERN) ; Ferraro, Rudy (CERN) ; Gulin, Marco (CERN) ; Kozsar, Ioan (CERN) et al.
Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). [...]

LINAC4 Laser Profile and Emittance Meter Commissioning
/ Goldblatt, Aurélie (CERN) ; Andreassen, Odd (CERN) ; Boorman, Gary (JAI, UK) ; Bosco, Alessio (JAI, UK) ; Gibson, Stephen (JAI, UK) ; Hofmann, Thomas (Unlisted, CH) ; Roncarolo, Federico (CERN) ; Tagg, Joseph (CERN)
The CERN LINAC4 is now equipped with two laser profile and emittance meters, a basically non destructive measurement of the transverse beam profile, not limited by the beam power density. The light of a pulsed laser is trans- ported through optical fibers and focused into the 160 MeV/c $H^{-}$ beam. [...]

High Power X-Band Generation Using Multiple Klystrons and Pulse Compression
/ Woolley, Benjamin (CERN) ; Argyropoulos, Theodoros (CERN) ; Catalán Lasheras, Nuria (CERN) ; Esperante Pereira, Daniel (Valencia U., IFIC) ; McMonagle, Gerard (CERN) ; Rey, Stephane (CERN) ; Syratchev, Igor (CERN) ; Tagg, Joseph (Natl. Instruments, Baden) ; Volpi, Matteo (Melbourne U.) ; Wuensch, Walter (CERN)
CERN has constructed and is operating a new X-band test stand containing two pairs of 12 GHz, 6 MW klystrons. By power combination through hybrid couplers and the use of pulse compressors, up to 45 MW of peak power can be sent to any of 4 test slots at pulse repetition rates up to 400 Hz. [...]

Beam-Loading Effect on Breakdown Rate in High-Gradient Accelerating Structures
/ Tecker, Frank (CERN) ; Argyropoulos, Theodoros (CERN ; Valencia U., IFIC) ; Catalán Lasheras, Nuria (CERN) ; Corsini, Roberto (CERN) ; Degiovanni, Alberto (Unlisted, CH ; CERN) ; Gamba, Davide (CERN ; Oxford U., JAI) ; Giner Navarro, Jorge (CERN ; Valencia U., IFIC) ; Grudiev, Alexej (CERN) ; McMonagle, Gerard (CERN) ; Navarro Quirante, Jose Luis (Unlisted, CH ; CERN) et al.
The Compact Linear Collider (CLIC) study for a future electron-positron collider with a center-of-mass energy up to 3 TeV aims for an accelerating gradient of 100 MV/m. The gradient is limited by RF breakdowns, and the luminosity requirements impose a limit on the admissible RF breakdown rate. [...]

Effect of Beam-Loading on the Breakdown Rate of High Gradient Accelerating Structures
/ Navarro Quirante, Jose Luis (CERN) ; Corsini, Roberto (CERN) ; Degiovanni, Alberto (CERN) ; Döbert, Steffen (CERN) ; Grudiev, Alexej (CERN) ; Kononenko, Oleksiy (CERN) ; McMonagle, Gerard (CERN) ; Rey, Stephane (CERN) ; Solodko, Anastasiya (CERN) ; Syratchev, Igor (CERN) et al.
The Compact Linear Collider (CLIC) is a study for a future room temperature electron-positron collider with a maximum center-of-mass energy of 3 TeV. To efficiently achieve such high energy, the project relies on a novel two beam acceleration concept and on high-gradient accelerating structures working at 100 MV/m. [...]

Diagnostics and Analysis Techniques for High Power X-Band Accelerating Structures

The study of high gradient limitations due to RF breakdowns is extremely important for the CLIC project. A series of diagnostic tools and analysis techniques have been developed in order to monitor and characterize the behaviour of CLIC accelerating structures under high power operation in the first CERN X-band klystron-based test stand (Xbox1).
