美国 HI gamma S 设施中的伽马束以及目前在罗马尼亚建造的 ELI-NP 设施中预计的伽马束，为推进核天体物理学研究提供了独特的新机会；其中最重要的是通过精确测量（12）C（α，γ）反应来解决恒星氦燃烧过程中氧气形成的悬而未决的问题。使用低压气体（作为活动目标）运行的时间投影室 (TPC) 探测器非常适合此类研究。我们回顾了 HI gamma S 设施当前研究计划的进展以及未来的计划，其中包括光学读出 TPC (O-TPC) 以及 ELI-NP 设施电子读出 TPC (ELITPC) 的开发。
Gamma-Beams at the HI gamma S facility in the USA and anticipated at the ELI-NP facility, now constructed in Romania, present unique new opportunities to advance research in nuclear astrophysics; not the least of which is resolving open questions in oxygen formation during stellar helium burning via a precise measurement of the(12)C(alpha, gamma) reaction. Time projection chamber (TPC) detectors operating with low pressure gas (as an active target) are ideally suited for such studies. We review the progress of the current research program and plans for the future at the HI gamma S facility with the optical readout TPC (O-TPC) and the development of an electronic readout TPC for the ELI-NP facility (ELITPC).
