| Title | A Radial Time Projection Chamber for $a$ detection in CLAS at JLab | ||||
| Abstract | A new Radial Time Projection Chamber (RTPC) was developed at the Jefferson Laboratory to track low-energy nuclear recoils for the purpose of measuring exclusive nuclear reactions, such as coherent Deeply Virtual Compton Scattering and coherent meson production off $^4$He. In such processes, the $^4$He nucleus remains intact in the final state, however the CEBAF Large Acceptance Spectrometer (CLAS) cannot track the low energy $\alpha$ particles. In 2009, we carried out measurements using the CLAS spectrometer supplemented by the RTPC positioned directly around a gaseous $^4$He target, allowing a detection threshold as low as 12$\sim$MeV for $^4$He. This article discusses the design, principle of operation, calibration methods and the performances of this RTPC. | ||||
