The simulation of ion trajectories has made a big move. Now we are in the next compartment, which houses the einzel lens(es).
This compartment is an intermediate stage between the gas-filled ion guide and the ultra-high-vacuum MR-ToF. The ion-neutral collisions can safely be left out, which means a lot for the simulation. We will not deal with randomness any more! The ion trajectories are more predictable and can easily be controlled by only einzel lens(es).
