VAriable Dipole for the Elettra Ring: Prototype acceptance test

The VAriable Dipole for the Elettra Ring (VADER) task, driven by the I.FAST European project (Deliverable 7.3), aimed at developing a prototype of a new full length variable field dipole design magnet which includes a transverse gradient allowing a further reduction of the horizontal emittance in the upgraded ELETTRA storage ring. A prototype of this magnet was designed by the CIEMAT laboratory and fabricated by KYMA company. This note presents and discusses the magnetic measurement serving as acceptance tests of the magnet prototype conducted at ELETTRA.
