MCP with delay-line anode used for position sensitive detector at Rare RI Ring

The Rare RI Ring (R3) aims at measuring masses of exotic nuclei with precision of 10⁻⁶. In order to achieve this goal, the beam diagnostics is needed at the beam line to improve the transport efficiency and measure the velocity of nuclei of interest. For this purpose, we are developing position sensitive detectors with lower energy loss than conventional beam line detectors. We report the development of the foil position sensitive detector based on micro-channel plates (MCPs) with a delay-line anode. (author)
