The reflector or reflectron has been developed by Mamyrin. [35] In the reflector TOF analyzer - often abbreviated ReTOF - the reflector acts as an ion mirror that focuses ions of different kinetic energies in time. Its performance is improved by using two-stage or even multistage reflector designs. 

Figure 3.11 Schematic of a time-of-flight mass analyzer with reflectron proposed by Mamyrin,11 Ions of higher kinetic energy penetrate more deeply into the reflecting field and are delayed in comparison to ions of lower kinetic energy. The delay compensates for differences in transit time of the field-free regions. Ions produced e.g., by focused laser or primary ion beam.

Great improvements in the resolution of time-of-flight spectrometers followed the introduction of the reflectron (Mamyrin, 1994). Further enhancements in resolution were realized when time-delay extraction...

The concept of the TOF mass analyzer was first proposed by Stephens in 1946 [3], and the first instrument was demonstrated by Cameron and Eggers in 1948 [4]. Since then, several important advances in TOF technology have occurred, including time-lag focusing and two-stage acceleration techniques demonstrated by Wily and McLaren in 1955 [5], reflec-tron configuration demonstrated by Mamyrin et al. in 1973 [6], and curved-field reflectron demonstrated by Cornish and Cotter in 1993 [7].
