  The MIPP experiment operating with an upgraded data acquisition system will
be capable of acquiring data at the rate of 3000 events per second. Currently
we are limited to a rate of 30 Hz due to the bottlenecks in the data
acquisition electronics of the Time Projection Chamber (TPC). With the speeded
up DAQ, MIPP will be capable of acquiring data at the rate of $\approx$5
million events per day. This assumes a conservative beam duty cycle of 4~sec
spill every 2 minutes with a 42% downtime for main injector beam manipulations
for the $\bar{p}$ source. We show that such a setup is capable of producing
tagged neutron, anti-neutron and $K^0_L$ beams that are produced in the MIPP
cryogenic hydrogen target using proton, anti-proton and $K^{\pm}$ beams. These
tagged beams can be used to study calorimeter responses for use in studies
involving the Particle Flow Algorithm (PFA). The energy of these tagged beams
will be known to better than 2% on a particle by particle level by means of
constrained fitting. We expect a tagged beam rate in the tens of thousands a
day. The MIPP spectrometer thus offers a unique opportunity to study the
response of calorimeters to neutral particles.
