| TUPE29 | Integration of a Stripline Kicker Prototype for CLIC Project Into ALBA Storage Ring | 230 |
|
||
| The Compact Linear Collider (CLIC) project is an international collaboration with CERN for developing a high-energy and high-luminosity machine which accelerates and collides electrons and positrons at energies up to several tera-electron volts. The extraction system for the Damping Rings of the CLIC shall follow very tight requirements in order to maintain the ultra-low emittance of the extracted bunches. A first prototype of the extraction kicker based on stripline technologies has been built and characterized at CERN without beam. The stripline chamber will be shortly installed in the ALBA Synchrotron to be tested under beam. In situ measurements of the impedance, transversal field homogeneity and flat-top ripple aims to complete its characterization. This contribution presents the design of the set up for the integration of the stripline chamber in one of the medium straight sections of ALBA storage ring. | ||

| WEPE40 | Two-rotation Mechanism for an in Vacuum Beamstop | 378 |
|
||
|
At Small-angle X-ray Scattering beamlines (SAXS), beamstops are needed to block the intense primary beam that has not been scattered by the sample in order to protect the detector from any damage. Beamstops are usually confined inside a vacuum tube minimizing air space between the sample and the detector. For certain experiments, a motorized beamstop is required to achieve a precise positioning in different regions of the detector active area. ALBA has developed a new motorized beamstop* consisting of a two-rotation mechanism inside vacuum that composes a movement able to cover all range of the active area of the detector. The presented solution involves a main rotation reached by a gear and a worm drive actuated by a stepper motor and a second rotation relative to the main one produced by a piezo rotation stage. For each position appears two different solutions. This characteristic permits take two equivalent images in the detector with the same beamstop position but different orientation in the beamstop support; thus permitting the compensation of the support shadow on the active area of the detector.
