The EXCYT Project
The availability of radioactive beams will give new opportunities of research in nuclear
physics and in related fields.
The aim of the EXCYT project* (Exotics with Cyclotron and Tandem)
is the development of a facility for producing and accelerating exotic beams
from 0.2 up to 8 MeV/amu and it is based on the two accelerators method:
a beam axially injected by ECR source SERSE and accelerated by the CS will produce the required nuclear species
in a target-source complex, while the Tandem acts as the final accelerator. * The EXCYT project is funded by INFN as a Special Project with the 50% contribution from the European Fund for Regional
Development.
In order to produce secondary beams as intense as possible, a primary light beam (A<48) of 1 pmA,
80 Mev/amu, will be delivered by the cyclotron.
The target-ion source complex is followed by a high resolution isobar separator, consisting
of a pre-separator and two main stages. It is designed to provide an overall mass resolution
power of 20000.
The secondary beam, will be either accelerated by the Tandem, or used for experiments without further acceleration
(low energy beam, 300 KeV). The use of a Tandem as post-accelerators will provide a beam
particularly suitable for nuclear physics experiment:
low emittance (less than 0.5p mm mrad);
energy spread (DE/E=10-4);
possibility of continuous variation of the energy value (0.2-8 MeV/amu).
The expected intensity of secondary beams (A<60) is shown in table.
The first planned beam is 8Li with an initial maximum foreseen intensity of 105pps.
