TI - Detailed Characterization of ALBA Quadrupoles for Beta Function Determination J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Beta function value at quadrupoles for a circular accelerator can be determined using the relationship between the machine tune and the quadrupole strength. ALBA Storage Ring quadrupoles were measured during manufacturing, to be sure that their performance fitted the specifications. However, measurements were done at a number of currents that are not enough for an accurate determination of the beta function value. In fact, at least 1% error in the calibration of the hysteresis curve slope of the quadrupole is required, and therefore new detailed measurements of the hysteresis cycle are needed. In order to make these measurements, spare quadrupoles existing at ALBA have been used. In this paper we present the results of beta function values determination using this method for ALBA storage ring.
