IMPLEMETATIONS ON THE RF CHARGE BREEDER DEVICE BRIC WITH TEST MEASUREMENTS

The "charge state breeder" BRIC (BReeding Ion Charge) is based on an EBIS source and it is designed to accept RIB with charge state +1, in a slow injection mode, to increase their charge state up to +n. BRIC has been developed at the INFN section of Bari (Italy) during these last 4 years with very limited funds and it has been assembled at the LNL (Italy) laboratory. The new feature of BRIC, with respect to the classical EBIS, is given by the insertion, in the ion drift chamber, of a Radio Frequency (RF) - Quadrupole aiming to filtering the unwanted masses and then making a more efficient containment of the wanted ions. The RF test measurements seem confirm, as foreseen by simulation results that a selective containment can be obtained. Most accurate measurements, however, are needed to study with more details that effect. For this reason, few implementations of the system have been studied to improve the accuracy of the measurements. The main implementation carried out on BRIC is given by the new and more efficient ion extraction system that recently has been mounted on our device. On this contribution we will shortly discuss the test measurements problems we had to face with our implemented device.
