Claim 25:
26. A method for determining a beam energy of a particle beam comprising the steps:
(a) allowing the particle beam to fall on a particle energy measuring device that comprises
(i) at least twenty capacitors that
each comprise a first capacitor plate and
each comprise a second capacitor plate and
are arranged one behind the other with respect to a beam incidence direction,

(ii) a multiplexer that has
a multiplexer outlet and
a plurality of multiplexer inputs, wherein each multiplexer input is connectable to precisely one of the at least twenty capacitors and
wherein said multiplexer is configured to connect a first capacitor plate of the respective capacitor to the multiplexer outlet,

(iii) a plate charge measuring device that comprises
a plate charge measuring device input, which is connected to the second capacitor plates, and
a plate charge measuring device outlet,

(b) successively measuring the capacitor charges (Qn) by the plate charge measuring device by successively connecting the at least twenty capacitors to the plate charge measuring device using the multiplexer, thereby obtaining charge data, and
(c) calculating particle energy (S) and/or a beam charge (Q26) from the charge data.
