ACTAR TPC

Presentation

ACTAR TPC is a French project aiming at constructing a new-generation active target in order to study very rare nuclear processes and nuclei produced in very small quantities.

This state-of-the-art detector is able to record the charged particle trajectories using a pad plane composed of 128×128 pads of 2 mm side. Each pad is equipped with digital electronics, which permits to sample the active volume of ACTAR TPC into 8 Mega voxels, at a rate of 100 Hz. The active target will be used with low-intensity SPIRAL 1 beams and high energy fragmentation beams in order to study extreme phenomena in nuclear matter.

With its relatively small size, ACTAR TPC is meant to be easily transported to other facilities to exploit beams that cannot be produced at GANIL.

Scientific goals

ACTAR TPC@GANIL:

  • Physics of ACTAR TPC@GANIL concerns the study of excitation functions with very exotic nuclei, to perform spectroscopic studies beyond the drip line, and the excitation of very collective states such as giant resonances or cluster states.
  • It benefits from the use of the fast fragmentation beams of the LISE spectrometer for inelastic scattering studies
  • It benefits from the availability of post-accelerated radioactive SPIRAL1 ions-beams for resonant scattering and transfer reactions.
  • It can be coupled to a large variety of detectors such as MUST2 and FAZIA.
