Description
We present the development and performance evaluation of two Active-Target Time Projection Chambers (AT-TPCs): a cylindrical-shaped model (TPC-Drum) and a parallelepiped-shaped prototype. These serve as stepping stones for the AT-TPC intended for the low-energy Large Acceptance Multi-Purpose Spectrometer (LAMPS) experiment at RAON. The primary objectives of the TPC-Drum include testing the performance of approximately 1000 readout channels in a magnetic field and investigating alpha clustering structure in rare isotopes and excited alpha-conjugate nuclei, such as C-12 and O-16. Performance tests of the prototype AT-TPCs were conducted using a 200 MeV/u carbon beam at the Heavy Ion Medical Accelerator in Chiba (HIMAC). The results provide valuable insights for the development and optimization of the large scale AT-TPC for low energy experiments.
