The First Isochronous Mass Measurements at CSRe
-
摘要: With the commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou (HIRFLCSR), a pilot experiment operating the CSRe in isochronous mode to test the power of HIRFLCSR for measuring the mass of the shortlived nucleus was performed in December of 2007. The fragments with A/q = 2 of 36Ar were injected into CSRe and their revolution frequencies were measured with a fast time pickup detector with a thin foil in the circulating path of the ions. The preliminary result is presented. The result shows the potential of CSRe for mass measurements of shortlived nuclei.
