چکیده

The paper presents the control of a power supply feeding a quadrupole magnet of a booster synchrotron. The supply equipment is based on a switching architecture where current sharing and interleaving techniques are adopted to minimize the voltage/current ripple. Internal model principle is exploited in the control design to guarantee extremely accurate tracking of the sinusoidal current reference for the quadrupole magnet. PWM-based digital solution is adopted instead of analog hysteresis one to avoid unpredictable behaviors of the current ripple and to allow a simple and reliable implementation of the proposed controller. Extensive simulations confirm satisfactory performances. Copyright c ©2005 IFAC

Digital Signal Processing for Beam Position Feedback

Stabilization of the particle beam position with respect to the focusing optics in the third generation synchrotron light sources is crucial to achieving low emittance and high brightness. For this purpose, global and local beam orbit correction feedbacks will be implemented in the APS storage ring. In this article, we will discuss application of digital signal processing to par-ticle/photon be...

A microbeam irradiator without an accelerator

The stand-alone microbeam, under development at RARAF, presents a novel approach to biological microbeam irradiation studies. Foregoing a conventional accelerator as a source of energetic ions, we propose to use a small, high-specific-activity, alpha emitter. Alpha particles emitted from this source are focused using a compound magnetic lens consisting of 24 permanent magnets arranged in two qu...
