  For Project X Fermilab Main Injector will be required to provide up to 2.3 MW
to a neutrino production target at energies between 60 and 120 GeV. To
accomplish the above power levels 3 times the current beam intensity will need
to be accelerated. In addition the injection energy of Main Injector will need
to be as low as 6 GeV. The current 30 year old Main Injector radio frequency
system will not be able to provide the required power and a new system will be
required. The specifications of the new system will be described.
