Description
We develop an active-target Time Projection Chamber (aTPC) operated in a low-pressure, strong magnetic field. The aTPC comprises a cathode plane, four field-cage planes, a gating GEM (Gas Electron Multipliers) plane, a triple GEM structure, and a pad plane. The pad plane covers 10 x 10 cm2 with 1000 3x3 mm2 square pads. The construction of the detector is in progress, and the expected performance is verified using Geant4 and Garfield++ simulation. We will primarily focus on the cross-section measurement for oxygen production from the 12C(α,γ)16O reaction and potassium destruction through the reverse 37Cl(α,n)40K and 40Ar(p,n)40K reactions. This talk will present the current R&D status.
