ASMS TERMS AND DEFINITIONS POSTER ENTRY
Dual stage reflectron

A reflectron in which two retarding fields are used to reverse ion velocities. Generally, both retarding regions are constant field, each achieved by retarding voltages that increase linearly with reflectron depth. In the most common embodiment, ions are retarded by two-thirds to three-quarters of their mean kinetic energies within the first retarding regions which comprises approximately 10% of the total reflectron depth.
