THYFI — Beam Instrumentation and Feedback 29-Jun-06 11:00 - 11:30 THYFI — Beam Instrumentation and Feedback Ionization Profile Monitoring at the Tevatron Ionization Profile monitors have been used in almost all machines at Fermilab. How- A. Jansson (Fermilab) ever, the Tevatron presents some particular challenges with its two counter-rotating, small beams, and stringent vacuum requirements. In order to obtain adequate beam size accuracy with the small signals available, custom made electronics from particle physics experiments was employed. This provides a fast (single bunch) and dead-timeless charge integration with a sensitivity in the femto-Coulomb range, bringing the system close to the single ionization electron detection threshold. The detector itself is based on a previous Main Injector prototype, albeit with many modifications and improvements. The first detector was installed at the end of 2005, with a second detector to follow during the spring shutdown. The ultimate is to continuously monitor beam size oscillations at injection, as well as the beam size evolution during ramp and squeeze. Chair: M.C. Ross (SLAC, Menlo Park, California) 383 THYFI01
THOBFI01 THOBFI02 THOBFI03 29-Jun-06 11:30 - 12:30 THOBFI — Beam Instrumentation and Feedback THOBFI — Beam Instrumentation and Feedback A Sub 100 fs Electron Bunch Arrival-time Monitor System for the VUV-FEL F. Loehl, K.E. Hacker, F. Ludwig, H. Schlarb, B. Schmidt (DESY) A. Winter (Uni HH) The stability of free-electron lasers and experiments carried out in pump-probe configurations depends sensitively on precise synchronization between the photo-injector laser, low-level RF-systems, probe lasers, and other components in the FEL. A measurement of the jitter in the arrivaltime of the electron bunch with respect to the clock signal of a master oscillator is, therefore, of special importance. For this task, we propose an arrival-time monitor based on a beam pick-up with more than 10GHz bandwidth which permits measurements in the sub 100 fs regime. The RF-signal from the beam pick-up is sampled by an ultra-short laser pulse using a broad-band electro-optical modulator. The modulator converts the electron bunch arrival-time jitter into an amplitude modulation of the laser pulse. This modulation is detected by a photo detector and sampled by a fast ADC. By directly using the laser pulses from the master laser oscillator of the machine, any additional timing jitter is avoided. In this paper we present the layout of the system and first experimental results. Measurement of the Beam Profiles with the Improved Fresnel Zone Plate Monitor We present the recent progress of the FZP H. Sakai, N. Nakamura (ISSP/SRL) H. Hayano, T. Muto (KEK) (Fresnel Zone Plate) beam profile monitor constructed at KEK-ATF damping ring. This monitor based on an X-ray imaging optics with two FZPs*. In this monitor, the transverse electron beam image at bending magnet is twenty-times magnified by the two FZPs and detected on an X-ray CCD camera. Then the realtime and 2-dimentional transverse beam profiles can be obtained with non-destructive manner by using this monitor. The expected spatial resolution is less than 1 micro-meter. Recently, we install the new mechanical shutter to improve time resolution of the monitor and avoid the effects of the short-term movement of the beam or the monitor itself. By applying this shutter, the shutter opening time was reduced less than 1ms and the beam profile could be measured more accurately. In this paper, we report the new shutter performance and the measurement results of beam profiles by the improved FZP beam profile monitor. *K. Iida, et al. Nucl. Instrum. Meth. A 506 (2003) 41-49.

Tumaikin (BINP SB RAS) The opportunity of performing an experiment on high precision comparison of the electron and positron anomalous magnetic moments following the VEPP-2M experiment is under study at the VEPP-4M storage ring. The record accuracy of 1.5x10-8 was obtained for comparison of spin precession frequencies in the experiment on resonant depolarization with simultaneously circulating electron bunches, two of them polarized and one unpolarized. It is the first time when the spreading 384 Chair: M.C. Ross (SLAC, Menlo Park, California)
