Precision isochronous mass measurements at the storage ring CSRe in Lanzhou

Abstract : Direct mass measurements of 78Kr projectile fragments have been performed in the recently commissioned storage ring CSRe employing the isochronous mass spectrometry method. A new data-analysis technique has been developed to correct the drifts in the revolution frequencies caused by instabilities of the magnetic fields in the CSRe, thus yielding a mass resolving power of R=m/Δm≈1.7×105 (sigma). Masses for 45V, 47Cr, 49Mn and 51Fe nuclei are determined with a relative mass precision of δm/m≈2×10−7 (sigma) which is an improvement by a factor of not, vert, similar2 compared to the literature values.
