The multi-reflection time-of-flight mass spectrograph has recently become of great utility in the study of superheavy nuclei. The device efficiently uses each ion and its operation is amenable to the inclusion of a decay detector being coupled into the time-of-flight (TOF) ion impact detector. In this way, TOF-decay correlation can be measured to unambiguously differentiate low-yield radioactive ions from stable molecular ions or dark counts. This will eventually allow the technique to be applied to the study of extremely low-yield nuclei such as those of 
Nh and 
Mc isotopes.

Times Cited Count：10 Percentile：80.89(Physics, Nuclear)The atomic masses of 
Ag, 
Pd, Rh, Ru, and 
Mo have been measured with the ZeroDegree multi-reflection time-of-flight Mass Spectrograph (ZDMRTOF-MS) at the RIKEN RI beam factory. In most cases, good agreements between our results and available experimental data as well as the evaluated masses in AME2020. From the present results, we conclude that up to Mo there is no stabilizing shell effect corresponding to the harmonic oscillator gap at N = 70.

Times Cited Count：30 Percentile：96.38(Instruments & Instrumentation)A new MRTOF mass spectrograph was assembled following the ZeroDegree spectrometer at RIKEN RIBF. By using a pulsed-drift-tube technique to modify the ions' kinetic energy in a wide range, we directly characterized the dispersion function of the system for optimizing the voltages applied to the electrostatic mirrors. This enabled us to achieve a mass resolving power of 10
within a total time-of-flight of only 12.5 ms, making the spectrometer capable of studying short-lived nuclei possessing low-lying isomers.
