| WEPP01 | Filling Pattern Measurement Using a 500 MHz Digitizer at Soleil and APS Storage Rings | 96 |
|
||
| Filling pattern was measured at SOLEIL and APS storage ring using a 500 MHz digitizer. Various filling patterns were measured: from a single bunch to multi-bunch hybrid fill. The digitizer has 14-bit granularity and locks the sampling clock to exact RF frequency (352 MHz). Signals were sampled from the standard BPM pickup and from APD diode. Data were retrieved using Matlab and Labview interfaces and compared to existing systems. | ||

CIEL: Current Injection Efficiency and Lifetime | |
|
||
| We will introduce a new acquisition system for storage ring beam current monitor. It is based on the co-developped PandBox electronics, associated with a 24 bits 128kS/s ADC. It offers the possibility of fast, triggered captures to measure injected current even during bursted injections. We’ll show the results of the first tests and the integration of this new measure. | ||

New Beam Loss Monitor System at SOLEIL | |
|
||
| SOLEIL has recently upgraded its Beam Loss Monitor (BLM) system from pin-diode detectors to plastic scintillators associated with photosensor modules. This new kind of monitor, associated to its dedicated electronics, is able to measure slow or fast losses. Monitors have been carefully calibrated with a Cesium source, and installed at systematic locations on the storage ring to provide reliable loss amplitude comparison between them. SOLEIL storage ring is now equipped with 80 BLMs. Installation setup, calibration procedure and resulting measurements will be presented. | ||

BPM Studies and Prototype Design for the SOLEIL Upgrade | |
|
||
| Synchrotron SOLEIL is preparing a machine upgrade with a reduction by more than a factor 10 the horizontal electron beam emittance (< 100 pm.rad)., the future multibend achromat lattice will be composed of a large number of magnet elements. Quadrupole and sextupole strengths will impose a drastic reduction of the vacuum chamber dimensions and in particular its diameter that will be reduced to 10 mm. One of the challenges for the beam position monitors will be the mechanical integration of the 4 buttons and feedthroughs on such a small beam pipe. In this context we have realized a first prototype with Component Off The Shelf 3 mm buttons diameter, to validate this mechanical integration and are starting the 3D electromagnetic simulations to study the impedance characteristics, the RF parameters, the heating and thermal issues. | ||
