Abstract
An ion mirror is disclosed comprising an ion entrance electrode section () at the ion entrance to the ion mirror, an energy focussing electrode section () for reflecting ions back along a longitudinal axis towards said ion entrance, and a spatial focussing electrode section () arranged between the ion entrance electrode section () and the energy focussing electrode section () for spatially focussing the ions. One or more DC voltage supply is provided to apply a DC potential to the ion entrance electrode section () that is intermediate the DC potential applied to the spatial focussing electrode section () and the DC potential applied to the energy focussing electrode section (). The ion mirror further comprises: (i) at least one first transition electrode () arranged between said ion entrance electrode section () and said spatial focussing electrode section (), wherein said one or more DC voltage supply is configured to apply a DC potential to said at least one first transition electrode that is intermediate the DC potential applied to the ion entrance electrode section () and the DC potential applied to the spatial focussing electrode section (); and (ii) at least one second transition electrode () arranged between said energy focussing electrode section () and said spatial focussing electrode section (), wherein said one or more DC voltage supply is configured to apply a DC potential to said at least one second transition electrode () that is intermediate the DC potential applied to the spatial focussing electrode section () and the DC potential applied to the ion entrance electrode section ().
