TUO1B04 | Overview of Beam Optics in Project-X Superconducting SC CW Linac | 314 |
|

Project-X is a proposed multi-MW proton facility at Fermilab. Based on a new superconducting H- linear accelerator, it would provide the foundation for a flexible long term intensity frontier physics research program. Two machine configurations have been developed. The first one involves a single 8 GeV, pulsed linac (9 mA peak, 1 ms @ 5 Hz pulses) followed by accumulation and acceleration to 60-120 GeV in the existing Main Injector synchrotron. The second -and currently favoured one- replaces the single pulsed linac by a 3 GeV (10 mA peak, 1 mA average @ 325 MHz), continuous wave linac followed, up to 8 GeV, by either a rapid cycling synchrotron or a second (pulsed) linac. We present here an overview of beam optics for the 3 GeV CW linac. Constraints related to cryostat configuration, field limits in cavities, particle loss mechanisms, and the need for warm instrumentation sections are discussed. Alignment, field amplitude and phase tolerances are also addressed. |

THO1B05 | First LEBT Simulations for the Bilbao Accelerator Ion Source Test Stand | 595 |

The Proposed Multi-specimen Low Energy Transport System (LEBT) consists of a series of solenoids with tunable magnetic fields, used to match the characteristics of the beam to those imposed by the RFQ input specification. The design of the LEBT involves selecting the number of solenoids to use and their fixed positions, so that the set of fields that provides the desired matching can be found for any given conditions (different currents, input emittances, etc). In this work we present the first simulations carried out to design the Bilbao Accelerator LEBT, which were peformed using several codes (Track, GPT, Trace2D). The best configuration is discussed and evaluated in terms of the degree of matching to the RFQ input requirements. |
