Array for achromatic imaging of a pulsed particle ensemble
An array for achromatic imaging of a pulsed ensemble of charged particles is described. The device comprises an imaging system with a round lens optics (2, 7), a low-energy drift space (3) and an accelerator (4-6) driven by at least one rapidly switchable voltage U(t), such that the velocity and/or...

| Zusammenfassung: | An array for achromatic imaging of a pulsed ensemble of charged particles is described. The device comprises an imaging system with a round lens optics (2, 7), a low-energy drift space (3) and an accelerator (4-6) driven by at least one rapidly switchable voltage U(t), such that the velocity and/or trajectory of the particles in the ensemble is influenced and the particles starting from point (1) with different energies are crossing the image plane in one point (8), i.e. the chromatic aberration of the optics is compensated. |
