There are four orbiting electrodes and two injection/ejection electrodes on a palm sized optics bench. The Ion source gives kinetic-energy for orbiting motion in the infinit loop. Injection and ejection electrodes are synchronized with Ion source pulsing triggering. Injection electrodes has to be in the on state while ions enter the analyzer, then has to be turned off before first ion (smallest ion) returns to it. Orbiting electrodes are constant, so orbiting ion can be held until ejection electrode is ON.
The same kind of technologies such as multi-reflection-TOF are exist, but they usually have a measurable trade-off between sensitivity and resolution. The patented multi-turn optics made “perfect focusing” come true, and losing ions are about 1 to 2% per turn, which is related to mean free path in vacuum.
