Abstract

Five solenoid-based focusing lenses designed for use inside the SSR1 cryomodule of the PXIE test stand at Fermilab have been fabricated and tested. In addition to a focusing solenoid, each lens is equipped with a set of windings that generate magnetic field in the transverse plane and can be used in the steering dipole mode or as a skew quadrupole corrector. The lenses will be installed between superconducting cavities in the cryomodule, so getting sufficiently low fringe magnetic field was one of the main design requirements. Beam dynamics simulations indicated a need for high accuracy positioning of the lenses in the cryomodule, which triggered a study towards understanding uncertainties of the magnetic axis position relative to the geometric features of the lens. Furthermore, this report summarizes the efforts towards certification of the lenses, including results of performance tests, fringe field data, and uncertainty of the magnetic axis position.

Design and Performance of Focusing Lenses for Installation into Superconducting Cryomodules of a Proton Linac

Conference Nicol, Thomas H. ; Sergatskov, Dmitri A. ; Tartaglia, Michael A. ; ... - IEEE Trans.Appl.Supercond.

The high energy sections of the Fermilab HINS R&D proton linac will utilize superconducting spoke resonator (SSR) RF cavities. These will be assembled into cryomodules with strong solenoid focusing lenses closely interleaved with the cavities. A design for lenses has been made for the lower (SSR1) and higher (SSR2) energy ranges of the SSR-section. Prototype lenses for both SSR1 and SSR2 sections have been built and the SSR1 has been tested. Shielding is needed to reduce the solenoid fringe field on the cavity wall below the 10 μT level, and a preliminary design was built and tested with the SSR1more »« less

SSR1 Cryomodule Design PXIE

Conference Kazakov, S. ; Nicol, T. H. ; Passarelli, D. ; ... - Conf.Proc.

Fermilab is planning to design and build a Project X Injector Experiment (PXIE), a cw linac, as a means of validating the Project X concept, reducing technical risks, and obtaining experience in the design and operation of a superconducting pr oton linac. The overall facility will include an ion source, low and medium-energy beam transport sections, a radio frequency quadrupole, and two cryomodules containing superconducting cavities. One will contain nine half-wave resonators operating at 162. 5 MHz and six superconducting solenoids. The second will contain eight single spoke resonators (SSR1) operating at 325 MHz and four superconducting solenoids. This papermore »« less

Solenoid-based focusing in a proton linac

Conference Terechkine, I ; DiMarco, J ; Schappert, W ; ...

Development of solenoid-based focusing lenses for the transport channel of an R&D linac front end at FNAL (HINS linac) is in its final stage. Superconducting lenses for the room temperature RF section of the linac are assembled into individual cryostats and certified using a dedicated test stand. During this certification process, the optical axis of each lens relative to the cryogenic vessel is found in the warm and cold state. Lenses for the superconducting RF sections are ready for production, and development of a cryomodule (which contains multiple superconducting lenses and RF cavities) is in progress. Studies have been conductedmore »« less
