The Isochronous Mass Spectrometry (IMS) is a powerful technique developed inheavy-ion storage rings for measuring masses of very short-lived exotic nuclei.The IMS is based on the isochronous setting of the ring. One of the mainparameters of this setting is the transition energy $\gamma_{t}$. %Thetransition energy $\gamma_{t}$ plays an important role in the isochronous massspectrometry (IMS). It has been a challenge to determine the $\gamma_{t}$ andespecially to monitor the variation of $\gamma_{t}$ during experiments. In thispaper we introduce a method to measure the $\gamma_{t}$ online during IMSexperiments by using the acquired experimental data. Furthermore, since thestorage ring has (in our context) a relatively large momentum acceptance, thevariation of the $\gamma_{t}$ across the ring acceptance is a source ofsystematic uncertainty of measured masses. With the installation of twotime-of-flight (TOF) detectors, the velocity of each stored ion and itsrevolution time are simultaneously available for the analysis. These quantitiesenabled us to determine the $\gamma_{t}$ as a function of orbital length in thering. The presented method is especially important for future IMS experimentsplanned at the new-generation storage ring facilities FAIR in Germany and HIAFin China.
