Claim 0:
1. A particle energy measuring device for determining the energy of a particle beam with comprising
(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, each multiplexer input being configured to connect to precisely one of the at least twenty capacitors and
(iii) is configured to connect one of the first and second capacitor plates of the respective capacitor of the at least twenty capacitors to the multiplexer outlet,

(c) 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 at least twenty capacitors, and
(ii) a total charge measuring device outlet, and

(d) an analysis circuit which is connected to the total 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.
