  A multi-MW proton facility, Project X has been proposed and is currently under development at Fermilab. As part of this development program, we are constructing a prototype of the front end of the Project X linac at Fermilab. The construction and successful operations of this facility will validate the concept for the Project X front end, thereby minimizing the primary technical risk element within the Project. The Project X Injector Experiment (PXIE) can be constructed over the period FY12-16 and will include an H ion source, a CW 2.1-MeV RFQ and two SC cryomodules providing up to 30 MeV energy gain at an average beam current of 1 mA. Successful operations of the facility will demonstrate the viability of novel front end technologies that will find applications beyond Project X in the longer term.

Project X is a multi-megawatt proton facility being developed to support a world-leading program in Intensity Frontier physics at Fermilab. The facility is designed to support programs in elementary particle and nuclear physics, with possible applications to nuclear energy research. A Functional Requirements Specification has been developed in order to establish performance criteria for the Project X complex in support of these multiple missions, and to assure that the facility is designed with sufficient upgrade capability to provide U.S. leadership for many decades to come. This paper will describe the Functional Requirements for the Project X facility, their recent evolution, and the rationale for these requirements.

  Reliability Analysis is an essential part of designing any complex system in order to predict performance and understand availability. However modeling complex systems has been a challenging task due to the large number of components and inter-dependencies. The options have been custom written simulation packages, requiring large investment of programming and debugging time; or standard commercial software running for many days. In our research we developed a hierarchical method to represent the reliability model of “Project X,”* a proposed linear accelerator at Fermi National Accelerator Laboratory. The system is first divided into subsystems small enough to readily simulate. Each subsystem is then separately simulated and parameterized so they can be represented as simple blocks in the top level system diagram. This allows standard, commercial software to model systems with many tens of thousands of components without requiring many days of computer time. Simulation were run and compared with data gathered from existing accelerators.

  The Project X Injector Experiment (PXIE) is a prototype of the Project X front end. A 30 MeV 50 kW H beam will be used to validate the design concept of the Project X. This paper discusses a design of the accelerator enclosure radiation shielding and the beam dump. Detailed energy deposition and activation simulation were performed with the MARS15 code. The simulation results guided the design of the installation enclosure.
