1. An accelerating apparatus, comprising:
a plurality of acceleration cavity units including a plurality of acceleration cavities; and
a plurality of coupling cavity units each of which includes a coupling cavity, two adjacent acceleration cavities being electromagnetically coupled via the coupling cavity, wherein
the plurality of acceleration cavity units has a plurality of holes each of which is configured to form a coupling channel between an acceleration cavity and a coupling cavity;
each of the plurality of acceleration cavity units has a first plane, one end of one of the plurality of holes being on the first plane, and the first plane being a mounting surface for a coupling cavity unit;
each of the plurality of coupling cavity units has a second plane, and
the each of the plurality of acceleration cavity units is connected with one of the plurality of coupling cavity units by physically connecting the first plane with the second plane.
 
15. An accelerating apparatus, comprising:
a plurality of acceleration cavity units including a plurality of acceleration cavities; and
a plurality of coupling cavity units each of which includes a coupling cavity, two adjacent acceleration cavities being electromagnetically coupled via the coupling cavity, wherein
the plurality of acceleration cavity units has a plurality of holes each of which is configured to form a coupling channel between an acceleration cavity and a coupling cavity;
at least one of the plurality of holes is located at a location of an inner surface of the acceleration cavity where electromagnetic field strength is maximum.
