Periodic Report Summary 2 - SPECMAT (Spectroscopy of exotic nuclei in a Magnetic Active Target)

Our aim is to provide crucial experimental information for the understanding of key issues in the structure of atomic nuclei. We address especially the evolution of the structure in nuclei far from stability, available at recently-completed beam facilities such as HIE-ISOLDE at CERN. We will use the powerful technique of nucleon-transfer reactions to collect detailed information about the nuclei of interest.
The challenges in performing measurements with very weak beams of unstable nuclei are tackled by the SpecMAT detector, a novel instrument combining high luminosity, efficiency and energy resolution.

The main technical advances required for the realisation of the project concern the use of gamma-ray detectors in a strong (3 tesla) magnetic field. In the past months, we have tested combinations of novel scintillation materials, light-collection devices and read-out electronics in the field generated by a large MRI magnet. This resulted in the choice of the detectors for the array, that will surround the gas volume where the charged reaction products are tracked.

Following the assembly and commissioning of SpecMAT in 2017, we aim at performing the first experiments at HIE-ISOLDE in 2018.
