The Project X Injector Experiment (PXIE), a test bed for the Project X front end, will be completed at Fermilab at FY12-16. One of the challenging goals of PXIE is demonstration of the capability to form a 1 mA H⁻ beam with an arbitrary selected bunch pattern from the initially 5 mA 162.5 MHz CW train. The bunch selection will be made in the Medium Energy Beam Transport (MEBT) at 2.1 MeV by diverting undesired bunches to an absorber. This paper will present the MEBT scheme and describe development of its elements, including the kickers and absorber.

Status of Fermilab Project X

Fermilab, Batavia, USA

Project X, a high-power proton facility, will support world-leading programs in long base line neutrino physics, the physics of rare processes, and nuclear studies. It will be unique among accelerator facilities worldwide in its flexibility to support multiple physics programs simultaneously with MW class beams at the intensity frontier. Project X is based on a 3 GeV continuous-wave superconducting H⁻ linac. Further acceleration to 8 GeV, and injection into Fermilab's existing Recycler/Main Injector complex, will support long-baseline neutrino experiments. Project X will provide ~3 MW of total beam power to the 3 GeV program, simultaneously with ≥ 2 MW to a neutrino production target at 60-120 GeV. This talk will describe the Reference Design of Project X and status of the R&D program.

The Pulsed Linac is a will require over 200 9-cell, 1300 MHz cavities packed in 26 ILC type cryomodules to accelerate 1 mA average beam current from 3GeV to 8 GeV. The architecture of the RF must optimize RF power, beam emittance, and energy gain amid a large number of requirement and constraints. The pulse length is a critical issue. Ideally, a 26 ms pulse would allow direct injection into the Fermilab’s Main Injector, bypassing the need of the Fermilab’s Recicler. High loaded quality factors (QL) are also desirable to minimize RF power. These requirements demand an accurate control of the cavity resonant frequency disturbed by Lorentz Force Detuning and microphonics. Also the LLRF control system must regulate the RF amplitude and phase within tight bounds amid a long list of dynamic disturbances. The present work describes the simulation efforts and measurements at Fermilab facilities.
