energy deposition in beryllium target

Dear Fluka Users,

I am trying to calculate the energy deposition in a cylindrical pure
beryllium target as a result of a monoenergetic 60GeV proton beam. The
beam has a Gaussian distribution with sigmax=sigmay=3.5mm and enters the
target normal to the circular cross section of diameter 2.1cm. The
target is a 100cm long cylinder. I have got some results for total
energy deposition but they are about 40% less than MARS results obtained
by colleagues. I would appreciate it if you could take a quick look at
my input file (attached) and see if I am neglecting anything important
for calculation of total energy deposited in the target.

Kind Regards

Tristan
