The evolution of pairing correlations in exotic nuclei is a subject which has received much attention in recent years. Of specific interest is the role of pairing in neutron-rich isotopes, where the effects of weak binding and continuum coupling are important (See for example ).
The best tool to study these correlations is the (t,p) transfer reaction, particularly suited to probe the 2n pair density. Due to the compelling capabilities offered by Active Targets TPC detectors , it is natural to explore the use of a tritium gas target TPC, with an equivalent thickness 100 times larger than typical solid targets, enabling experiments with exotic beams in reverse kinematics with a very low intensity. We will discuss the conceptual design of a dedicated tritium TPC (AT3PC) for FRIB, based on an inner cell containing the gas  to minimize safety issues associated with large quantities of tritium.
