The Main Injector (MI) is going to use slip stacking scheme for the NuMI neutrino experiment for effectively increasing proton intensity to the NuMI target by about a factor two in a MI cycle. The MI is going to accept 11 pluses at injection energy from the Booster and accelerate them to 120 GeV. By using Slip stacking, two of them are merged into one and sent to Anti-proton production and 9 of them, one single and four doubled density pulses, are going to be sent to the Numi beam line. We have been doing low intensity beam studies with 11 pulses injection and accelerated them with the total intensity of 3·1012 ppp to 120GeV. We discuss beam loss and technical issues on multi-batch slip stacking.

The FLASH user facility providing free electron laser radiation is built based on the TTF project at DESY. Fermilab has the responsibility for the design and processing of a third harmonic, 3.9 GHz, superconducting cavity which is powered via a coaxial power coupler. Six power couplers have been manufactured at CPI after successful design of the power coupler including RF simulation, multipacting calculation, and thermal analysis. The power couplers are being tested and processed with high pulsed power in an elaborate test stand at Fermilab now. This paper presents the RF design and processing work of the power coupler.

As part of the research and development towards the International Linear Collider (ILC), several test facilities have been developed at Fermilab. This paper presents the latest LLRF results obtained with Capture Cavity II at these test facilities. The main focus will be on controls and RF operations using the SIMCON based LLRF system. Details about hardware upgrades and overall system performance will be also explained. Finally, design considerations and objectives for the future test facility at the New Muon Laboratory (NML) will be presented.
