  The latest generation of IPMs installed in the Fermilab Main Injector and
Recycler incorporate a 1 kG permanent magnet, a newly designed high-gain,
rad-tolerant preamp, and a control grid to moderate the charge that is allowed
to arrive on the anode pick-up strips. The control grid is intended to select a
single Booster batch measurement per turn. Initially it is being used to allow
for a faster turn-on of a single, high-intensity cycle in either machine. The
expectation is that this will extend the Micro Channel Plate lifetime, which is
the high-cost consumable in the measurement system. We discuss the new design
and data acquired with this system.
