Hello,

I copy my answer to the fluka mailing list.

Yes it is possible. It is even easier today thanks to recent improvements.

1 ) You define your region in the geometry section and assign some
adequate material (air in your case).
2) You define your beam characteristics through the new features of
BEAMPOS card (please refer to fluka's manual) using SDUM=CYLI-VOL in an
additionnal BEAMPOS card.
3) You define your detector by means of some adequate card (detector,
usrbin, usrtrack, resnuclei, etc.)

Hope it helps.

Best regards.

Sebastien.
