Claim 27:
28. 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 has
(i) a multiplexer outlet and
(ii) 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, and

(d) a total charge measuring device that comprises
(i) a total charge measuring device input, which is connected to the second capacitor plates for detecting a total charge (QΣ) of the charges on all of the least twenty capacitors, and
(ii) a total charge measuring device outlet.
