The First Isochronous Mass Measurements at CSRe

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 36Ar 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.
