Claim 26:
27. A particle energy measuring device for determining the energy of a particle beam with
(a) at least twenty capacitors that
(i) each comprise a first capacitor plate and
(ii) each comprise a second capacitor plate and
(iii) are arranged one behind the other with respect to a beam incidence direction,

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

(c) a plate charge measuring device that comprises
(i) a plate charge measuring device input, which is connected to the multiplexer outlet, and
(ii) a plate charge measuring device outlet, and
(iii) wherein the plate charge measuring device is configured to measure a charge (Qn) that flows via the multiplexer outlet and the plate charge measuring device input

(d) an analysis circuit which is connected to the plate charge measuring device and the multiplexer and is configured to automatically
(i) effect a switch from one of the multiplexer inputs to another of the multiplexer inputs, so that the at least twenty capacitors can be successively discharged, and
(ii) detect a charge (Qn) flowing from each of the at least twenty capacitors during the discharging process, thereby obtaining charge data from which the particle energy (E) is calculatable.
