TUPWA054	PXIE End-to-end Simulations	1829
	J.-F. Ostiguy, J.-P. Carneiro, V.A. Lebedev, A. Saini, N. Solyak Fermilab, Batavia, USA
	Funding: US DOE contract DE-AC02-76CH03000. Construction of PXIE, (Project-X Injector Experiment) has recently begun. The goal is to validate the design of the injector and low energy acceleration front-end for a future Project-X. PXIE operates in CW mode and consists in an ion source, a magnetically focused LEBT, a 162.5 MHz RFQ, a MEBT equipped with high bandwidth traveling wave kickers, a cryomodule equipped with 162.5 MHz half-wave resonators and a single cryomodule based on 325 MHz spoke resonators. The arrangement is meant to be closely representative of a future Project-X front end, and will include a variety of diagnostics. In this contribution we present detailed end-to-end tracking simulations. In particular, we examine possible impact of the RFQ longitudinal distribution, neutralization effects in the LEBT as well as of various imperfections in the MEBT on losses in the first superconducting cavities.

	Funding: US DOE under contract DE-AC02-76CH03000. Project-X is a high intensity proton source in development at Fermilab. At its heart is a linac based on superconducting technology comprising two distinct sections. The first one operates in CW mode and delivers beam with a flexible time structure to simultaneous experimental programs at 1 and 3 GeV. The second one operates in pulsed mode and accelerates a modest fraction (5%) of the beam from 3 GeV to 8 GeV for accumulation in the existing Main Injector complex. In an era of constrained budgets, construction in stages -with each stage capable of supporting worthy scientific programs - may be advantageous. Requirements for each program, coupled to the physical constraints imposed by the Fermilab site have led to a few possible scenarios, which are discussed in this contribution. In particular, we examine the implications of introducing bends in the linac at 1 and 3 GeV in terms of overall performance, flexibility and cost.

THPWO092	Update of Beam Optics and SRF Cavities for Project X	3975

	The Project X staging [1] requires reconsideration of the beam optics and thus, the SRF system for the 3 GeV CW linac of the Project X. The revised beam optics is presented in the paper as well as revised cavity design for SSR2 section and a new concept of the linac segmentation. The new versions for the Project X cryo-modules for the SSR2 section, low-beta 650 MHz section and high-beta 650 MHz section are discussed. The beam extraction scheme at 1 GeV is discussed also.
