  The NuMI beam at Fermilab produces a high-intensity neutrino beam for neutrino oscillation experiments. Since the start of 2005, NuMI has been delivering beam to the MINOS experiment. Greater than 2x10[20] 120 GeV protons have been delivered to the neutrino production target, with a peak power of 320 kW being achieved. This note reports on the status and operation of the beam and its technical components, including the target, horns, and instrumentation.

The NuMI beamline at Fermilab has been operational since the spring of 2005 delivering high-intensity neutrino beams to the MINOS experiment. A beam power on target of 310 kW has been achieved and a total of more than 2·1020 protons have been delivered to the NuMI target. Upgrades to NuMI are planned in preparation for the future MINERvA and NOvA neutrino experiments increasing the NuMI beam power capability from 400 kW to 700 kW and then as much as 1.2 MW. An overview of the future upgrade to NuMI is presented.

Estimates indicate that the electron cloud effect could be a limiting factor for Main Injector intensity upgrades, with or without a the presence of a new 8 GeV superconducting 8GeV Linac injector. The effect may turn out to be an issue of operational relevance for other parts of the Fermilab accelerator complex as well. To improve our understanding of the situation, two sections of specially made vacuum test pipe outfitted for electron cloud detection with ANL provided Retarding Field Analyzers (RFAs), were installed in the Tevatron and the Main Injector. In this report we present some measurements, compare them with simulations and discuss future plans for studies.
