Timing and/or position-sensitive MCP detectors, which detect secondary electrons (SEs) emitted from a conversion foil during ion passage, are widely utilized in nuclear physics and nuclear astrophysics experiments. This review covers high-performance timing and/or position-sensitive MCP detectors that use SE emission for mass measurements of exotic nuclei at nuclear physics facilities, along with their applications in new measurement schemes.

In this work, a multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) was adapted and employed, for the first time, for ultra-high resolution analytical tandem mass spectrometry. The device was deployed to analyze isobaric molecules in a heavy crude oil sample and to derive new structure formulas thanks to the device's ultra-high separation power and advanced data analysis techniques.
