Dear Hantao Jing,
I see no possibility to define a boundary crossing without a boundary.
If you need particle fluences independently on geometry you can use the
USRBIN in fluence mode. This, however will not give you energy or angular
The easiest thing is to segment your geometry with a dummy boundary.
