Multi-reflecting time-of-flight mass spectrometer with isochronous curved ion interface

A time-of-flight mass spectrometer apparatus comprising:

• a gas-filled ion trap for generating ion packets, said ion trap including at least one electrode to which a radio frequency signal is applied, wherein the ion packets are extracted from said ion trap after a predetermined delay after switching of said radio frequency signal;
• a time-of-flight mass analyzer for separating ions according to their mass-to-charge ratio;
• an ion receiver for receiving the separated ions;
• and
• a spatially isochronous energy filter positioned between said ion trap and said ion receiver for transferring ions within a limited energy range.

A hybrid time-of-flight mass analyzer apparatus comprising:

• at least one spatially isochronous set of electrostatic sectors;
• at least one ion mirror;
• and
• an ion receiver,
• wherein said ion mirror compensates for at least one second order time-of-flight aberration of the set of electrostatic sectors.

An apparatus comprising:

• an ion source for generating ions;

• a planar multi-reflecting time-of-flight analyzer having a drift space with periodic lenses;
• an ion receiver;
• and
• at least one spatially isochronous C-shaped cylindrical interface located in between said linear ion trap and said ion receiver.

A multi-reflecting time-of-flight mass spectrometer apparatus comprising:
