Abstract

The new LCLS-II Linear Superconducting Accelerator at SLAC needs superconducting magnet packages installed inside SCRF Cryomodules to focus and steer an electron beam. Two magnet prototypes were built and successfully tested at Fermilab. Magnets have an iron dominated configuration, quadrupole and dipole NbTi superconducting coils, and splittable in the vertical plane configuration. Magnets inside the Cryomodule are conductively cooled through pure Al heat sinks. Both magnets performance was verified by magnetic measurements at room temperature, and during cold tests in liquid helium. Test results including magnetic measurements are discussed. Special attention was given to the magnet performance at low currents where the iron yoke and the superconductor hysteresis effects have large influence. Both magnet prototypes were accepted for the installation in FNAL and JLAB prototype Cryomodules.

Performance of conduction cooled splittable superconducting magnet package for linear accelerators

Journal Article Kashikhin, Vladimire S. ; Andreev, N. ; Cheban, S. ; ... - IEEE Transactions on Applied Superconductivity

New Linear Superconducting Accelerators need a superconducting magnet package installed inside SCRF Cryomodules to focus and steer electron or proton beams. A superconducting magnet package was designed and built as a collaborative effort of FNAL and KEK. The magnet package includes one quadrupole, and two dipole windings. It has a splittable in the vertical plane configuration, and features for conduction cooling. The magnet was successfully tested at room temperature, in a liquid He bath, and in a conduction cooling experiment. The paper describes the design and test results including: magnet cooling, training, and magnetic measurements by rotational coils. Furthermore, themore »« less

SUPERCONDUCTING MAGNET PERFORMANCE FOR THE LCLS-II PROJECT

Conference Strauss, Thomas ; DiMarcom Joseph, DiMarcom Joseph ; Kiemschies, Oliver ; ... - IEEE Trans.Appl.Supercond.

The new LCLS-II Superconducting Linear Accelerator Cryomodules are under construction at Fermilab. Installed inside each SCRF Cryomodule is a superconducting magnet package to focus and steer an electron beam. The iron dominated magnet package has conductively cooled racetrack-type coils with both quadrupole and dipole windings. For ease of installation the magnet is splittable in the vertical plane. To confirm magnet specifications, we performed a quality acceptance in a liquid helium bath for quench testing, and we performed high precision magnetic field measurements. The magnetic and mechanical center alignment was investigated using the vibrating wire technique. Several prototypes and all productionmore »« less

Superconducting Magnet Performance in LCLS-II Cryomodules

Conference Kashikhin, V. ; Cheban, S. ; DiMarco, J. ; ...

New LCLS-II Linear Superconducting Accelerator Cry-omodules are under construction at Fermilab. Installed in-side each SCRF Cryomodule is a superconducting magnet package to focus and steer an electron beam. The magnet package is an iron dominated configuration with conduc-tively cooled racetrack-type quadrupole and dipole coils. For easier installation the magnet can be split in the vertical plane. Initially the magnet was tested in a liquid helium bath, and high precision magnetic field measurements were performed. The first (prototype) Cryomodule with the magnet inside was built and successfully tested at Fermilab test facility. In this paper the magnet package is discussed, themore »« less

Cryogen free superconducting splittable quadrupole magnet for linear accelerators

Conference Kashikhin, V S ; Andreev, N ; Kerby, J ; ...

A new superconducting quadrupole magnet for linear accelerators was fabricated at Fermilab. The magnet is designed to work inside a cryomodule in the space between SCRF cavities. SCRF cavities must be installed inside a very clean room adding issues to the magnet design, and fabrication. The designed magnet has a splittable along the vertical plane configuration and could be installed outside of the clean room around the beam pipe previously connected to neighboring cavities. For more convenient assembly and replacement a 'superferric' magnet configuration with four racetrack type coils was chosen. The magnet does not have a helium vessel andmore »« less

Commissioning of the LCLS-II Prototype HOM Detectors with Tesla-Type Cavities at Fast

Conference Sikora, John ; Diaz Cruz, Jorge ; Edstrom, Dean ; ... - JACoW

Experiments at the Fermilab Accelerator Science and Technology* (FAST) facility detected electron beam-induced high order mode (HOM) signals from Tesla superconducting cavities. This paper describes some of the signal detection hardware used in this experiment, as well as measurements of the HOM signal magnitude versus beam trajectory. These measurements were made both with a single bunch and with a train of 50 bunches at bunch charges from 400 pC/b down to 10 pC/b. The detection hardware is designed for use with the Tesla superconducting cavities of LCLS-II at SLAC** and is based on a prototype already in use at Fermilab.more »« less
