The acceptance required to capture an incoming particle by the stored
beam is given by:
In the case of an injected beam, the acceptance required to capture it is the one of the particle that requires the largest acceptance.
The acceptance required to capture the beam is shown, for the first 10
turns, in figure 24, for the four different
scenarios. The dynamic acceptance of the lattice ( 35 mm-mrad)
is large enough to capture the injected beam. A nice feature of the evaluation
of the acceptance by tracking is that we can appreciate the effects of the
non-linearities, as can be seen by the change of the acceptance turn to
turn.
