The SpecMAT project aims at using nucleon-transfer reactions to study crucial regions of the chart of nuclei, to understand the features of the underlying forces that drive shell evolution. Initially, we will focus on the neutron-rich nuclei around nickel (Z=28) and, for the first time, the neutron-deficient nuclei around lead (Z=82). SpecMAT is an active-target detector that combines high luminosity, high efficiency and a very large dynamic range and allows detection of both charged-particle and gamma-ray radiation. Advanced technologies are exploited in its design, concerning the use of electronics, gaseous detectors and gamma-ray detectors in a magnetic field. The detector will be installed in the ISS magnetic solenoid, at the HIE-ISOLDE facility for the production and post-acceleration of radioactive ion beams at CERN in Geneva.
The main physics cases will be briefly presented, along with an overview of the status of the project.
