Description
Cluster formation is a fundamental phenomenon in nuclear physics and is crucial for understanding nuclear structure and dynamics. To study cluster formation in nuclei, we use quasi-free knockout reactions with a proton probe to directly measure clusters formed in the nucleus. This approach, combined with inverse kinematics, allows measurements over a wide range of nuclei.
To implement this method, we are constructing a TOGAXSI telescope consisting of a silicon strip tracker and a calorimeter made of GAGG(Ce) scintillators. GAGG(Ce) is particularly suitable for (p, pX) reaction measurements due to its high density, fast response, high light output, and non-hygroscopic properties. The TOGAXSI telescope consists of over 100 large GAGG(Ce) crystals.
We have encountered challenges in the energy calibration and mass integration of the GAGG(Ce) crystals. We performed inverse-kinematics cluster-knockout measurements at RIKEN RIBF using TOGAXSI. In this talk, we will report on the development status and performance evaluation of the GAGG(Ce) calorimeter based on the insights obtained through this experiment.
