TL;DR: A high performance Time-of-Flight detector has been designed and constructed for isochronous mass spectrometry at the experimental Cooler Storage Ring (CSRe) as discussed by the authors, which has been successfully used in an experiment to measure the masses of the N approximate to Z approximate to 33 nuclides near the proton drip line.

TL;DR: X-ray burst model calculations with the new mass excess of (65)As suggest that the majority of the reaction flow passes through (64)Ge via proton capture, indicating that ( 64)Ge is not a significant rp-process waiting point.

TL;DR: In this article, 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 / Δ m ≈ 1.7 × 10 5 (sigma).
