Active targets and time projection chambers for nuclear physics

Abstract : The use of active targets and time projection chambers in nuclear physics experiments can be traced back nearly 30 years. These detectors have found profitable applications due to their intrinsic high efficiency and their ability to be operated with a very large effective target thickness while maintaining the ability to track low-energy recoil particles. The combination of rapidly decreasing beam intensities for nuclei produced furthest from stability with the properties of reactions performed in inverse kinematics provides an ideal niche for such “high-luminosity” detection systems at rare-isotope beam facilities around the world. Recent developments in micro-pattern gaseous detector technology, high-density mechanics and front-end electronics and high throughput data-acquisition systems now overcome many of the limitations associated with many of the existing detection systems. As a result, these detectors and their potential applications in nuclear physics are undergoing a renaissance with a large number of state-of-the-art detector development projects are underway. In this talk, we provide an introduction to the concept and detection principles of an active target and time projection chamber, review some of the existing detector technologies and physics programs, and present some of the planned and ongoing detector projects around the globe.
