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 (HIRFL-CSR),a pilot experiment operating the CSRe in isochronous mode to test the power of HIRFL-CSR for measuring the mass of the short-lived nucleus was performed in December of 2007.The fragments with A/q=2 of 36 Ar were injected into CSRe and their revolution frequencies were measured with a fast time pick-up 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 short-lived nuclei.
