MRTOF-S: a toolkit for pre-estimating precise mass measurements using MRTOF spectrometer

An accurate estimation of the masses of exotic nuclei is important for obtaining a better understanding of the nuclear structure and for astrophysical calculations. Because most nuclear masses of unstable isotopes far from beta stability are highly uncertain, precise mass measurements are necessary. Among recent advanced techniques, the multiple-reflection time-of-flight (MRTOF) has emerged as a good device for measuring the precise masses of short-lived isotopes with high mass-resolving power. Before conducting mass measurements in laboratories, it is necessary to pre-estimate the beam production rate, separability of ions, mass resolving power, etc. Hence, a computer code named MRTOF simulator (MRTOF-S) was developed. In this study, we report the development procedure, usage, and application of the MRTOF-S toolkit.
