CSRe Atomic Mass Spectrometer (CSRe-AMS) is dedicated to precision mass measurements of short-lived nuclides. It was established firstly in 2007 and has been updated gradually along the following years. Currently there are 3 time-of-flight (TOF) detectors to measure the revolutions times of ions stored in CSRe. The data acquisition system consists of two digital oscilloscope with sampling rates of 80GHz and 100GHz, respectively. A parallel computations based on GPU has been set up for fast on-line data analysis.
In the past few years, a series of mass-measurement experiments have been performed using isochronous mass spectrometry (IMS) in CSRe. Meanwhile, a new IMS scheme with double-TOF system is under test. The Schottky mass spectrometry based on beam cooling is also under development.
