State of the art free electron laser and linear collider
projects require a tight control of emittance dilution
caused by transverse wake field of misaligned components. An attractive option in RF structures are wake field
monitors (WFMs), measuring directly internal transverse
higher order modes.In collaboration between CERN, PSI and

To reach a high accelerating gradient of 100 MV/m, the CLIC project under study at CERN uses a 23 cm long tapered normal-conducting travelling wave Accelerating Structure (AS) operating at 12 GHz. To preserve beam emittance at the 1 nm vertical-size collision point, 7 μm accuracy is required in the pre-alignment of the AS wrt the supporting girder. We have developed a dedicated test bench...

The Beam Position Monitor (BPM) studied in the frame of the PACMAN project and used for CLIC is a passive resonant cavity operating at about 15GHz, optimized for holding both good spatial (<50nm) and temporal resolutions (<50ns). This BPM has been fully characterized with stretched-wire techniques on a standalone test bench. The nanometric spatial resolution has also been observed through an...

Radio frequency resonant cavity beam position monitors (CBPMs) offer stable nano-meter scale (10s to 100s nm) resolution measurement of transverse beam positions in particle accelerators. The performance of these devices depends critically on system considerations, such as calibration and operation. This talk outlines the main issues with stably operating CBPMS, RF processing, calibration and...

The rotating coil is one of the preeminent methods used to characterize the magnets’ harmonics content and magnetic center. The rotating coil technique for magnetic measurements of accelerator magnets uses complex patterns of passive coil transducers with the aim to reach the most accurate and precise measurements.

To achieve the tight alignment requirements demanded for CLIC, its components need to be pre-aligned on a common support within the micrometer range. Among these components, the main beam quadrupoles will be pre-aligned with respect to their magnetic axis by using the vibrating-wire technique. The measurement method and the characteristics of the PACMAN stretched-wire system will be...

The European Synchrotron Radiation Facility (ESRF) has started a major upgrade: the present storage ring will be dismantled in 2019 and will be replaced by a new one. More than 1000 magnets, with apertures ranging from 25 mm up to 37 mm, will be installed. Most of these magnets will be measured with Single Stretched Wire (SSW) benches developed in house.

Dr Stephane Sanfilippo (Paul Scherrer Institut)13/06/2016, 17:10
The talk will be mainly focused on the magnetic measurement techniques and systems used at the Paul Scherrer Institut (PSI) to characterize the field quality and qualify the magnetic elements (magnets and undulators) needed in the large scale facilities. In the frame work of the Swiss Free Electron laser (SwissFEL), the next facility in construction at PSI, the techniques for magnetic...
