Description

Beside the Uranium Carbide (UCx) target that will be used in SPES (Selective Production of Exotic Species) project, a SiC target will he first to be used to deliver some p-rich beams and validate the function of the SPES facility. Hitting SiC target with protons, one of the elements coming out from nuclear reaction is Aluminum with its isotopes. In order to obtain an Aluminum ion beam, among various type of ionization techniques, main effectiveness is expected from laser photo-ionization. In the past off line studies on laser photoionization have been made in Pavia Spectroscopy Laboratory, testing the selective laser photoionization on Aluminum Hollow Cathode Lamp as atomic source. At Laboratori Nazionali di Legnaro, recently a XeCl excimer laser was installed in order to provide laser ionization in the hot cavity and start first measurements. Results are promising to justify further studies with this technique, aiming a better characterization of the SPES ion extraction capability under laser photoionization. Furthermore with the incoming Wien filter will be possible to monitor the selectivity of the process.
