Characterization of a double Time-Of-Flight detector system for accurate velocity measurement in a storage ring using laser beams

Charge resolution in the isochronous mass spectrometry and the mass of $$^{51}$$Co

“…A lower number of stored ions in an individual injection will also lead to a higher resolution. Two timing detectors, a new IMS method that is under development and which will be applied in future experiments at the CSRe [12,29,[38][39][40][41], could also increase the charge resolution. Finally, MCP plates with 2 lm of pore size will be adopted, thus boosting the number of microchannels.…”

Heavy-ion storage rings and their use in precision experiments with highly charged ions

“…Another proposed solution is to install two ToF detectors in the straight section of the ring. Since the distance between the detectors can be measured with high precision [174], the difference of time signals for the same ion provides directly its velocity. Due to space restrictions, it is not feasible to install two ToF detectors in the ESR.…”
