Beck,

Maggies typically use relatively tight coupling between the primary and
secondary of the driver (0.4 - 0.6). As you increase the coupling
coefficient, it becomes increasingly difficult to quench the spark gap.
Magnifiers often require series rotary gaps (multiple electrode pairs
connected in series) to increase the rate at which the electrodes are
separated to achieve adequate quenching. Static gaps will not suffice in
this application.
