چکیده
The 0.8 GeV storage ring Super-ACO is now fully equipped with undulators. Two new undulators have been recently installed. Their effects on beam dynamics have been studied. In addition, new developments are continuously in progress in order to optimize the beam performances for the users. A beam position feedback system is now operational. A 500 MHz RF cavity allows to reduce the bunch length and increase the FEL gain. A feedback system on betatron tunes has been tested using a very precise detection. Some experiments on beam dynamics have been performed in order to understand and improve beam lifetime. The variation of tunes with momentum has been measured, for several configurations of undulators (up to 6 undulators closed), and compared with computed results.

Storage ring free electron laser dynamics in presence of an auxiliary harmonic radio frequency cavity
In a Storage Ring Free Electron Laser (SRFEL) there is a strong interdependence between the laser beam and the electron beam from which the laser is generated. The Super ACO storage ring has a second Radio Frequency (RF) cavity at the 5th harmonic of the main RF cavity. It is used to shorten the bunch length, thereby enhancing the laser gain. Employing this RF harmonic cavity instabilities are ...
متن کاملNon-linear Transverse Beam Dynamics Studies in the Super-aco Storage Ring*
Experimental turn by turn beam position measurements were performed in order to investigate the non-linear beam dynamics in Super-ACO. The aim of these experiments is to get a better understanding of the aperture limiting effects of non-linearities and to check the model used in tracking studies. The amplitudedependent tune shift measurements allow to highlight a strong octupolar-like component...
متن کاملChaotic dynamics in a storage-ring Free Electron Laser
The temporal dynamics of a storage-ring Free Electron Laser is here investigated with particular attention to the case in which an external modulation is applied to the laser-electron beam detuning. The system is shown to produce bifurcations, multi-furcations as well as chaotic regimes. The peculiarities of this phenomenon with respect to the analogous behavior displayed by conventional laser ...
متن کاملFuzzy sliding-mode control for ball and beam system with fuzzy ant colony optimization
This paper mainly addresses the balance control of a ball and beam system, where a pair of decoupled fuzzy sliding-mode controllers (DFSMCs) are proposed. The DFSMC has the advantage of reducing the design complexity, in which the coupling dynamics of the state-error dynamics are considered as disturbance terms. Stability analysis of the ball and beam system with DFSMCs is also discussed in det...
متن کاملSmall Signal Gain of the Super Aco Storage Ring Fel
The gain per pass of a Storage Ring Free Electron Laser is a crucial quantity to be known for a correct operation of the laser. The relatively low gain exhibited by second generation machines, as in the Super ACO case, calls for the minimization of the losses of the optical cavity for obtaining the laser oscillation. However, the gain needs to be evaluated accurately also on FELs installed on t...
