None Ion beam disappears entering in quadrupole field

I'm trying to simulate a beamline with a quadrupole field, the code seems
to work fine with very low gradient ( < 0.001 T/m ) and is possible to
track the beam across the quadrupole, traversing it and appearing in the
other side (for that gradient value, the effect of the quad. field is
negligible ) ...  but when the gradient increases, the beams (there are 8
parallel beams really) begin to disappear inside the quadrupole... When my
maximum working gradient (11.3 T/m) is reached the beam disappears in the
middle of the "quadrupole zone", as if the particles vanished in the vacuum
(galactic)... In the vis.mac file the line "/tracking/verbose 1"  is
enabled, but the output seems to be normal, and no error message appears...
any idea?
thank you in advance
