“…Of those requirements, shown in Table I, keeping the magnetic axis position stable to within 5 microns during a 20% field strength variation is perhaps the most difficult. One design, made at Fermilab, is based upon superconducting racetrack coils supported within a laminated iron yoke structure; the design concept and test results for the first model magnet of this type (RTQ01) have been previously reported [2]- [3]. Subsequently this design has evolved in two important ways: first, the steering dipole coils were removed to a separate corrector element, to eliminate magnetization effects that complicate the center position dependence on coil excitation history.…”

“…During the first unsplittable model test [4] relatively strong coupling was observed between the quadrupole and dipole correctors wound on the top of quadrupole coils. This coupling through the superconductor magnetization [7], [8] adds an extra value to the quadrupole magnetic center shift during strength variations.…”

“…12). The center position was derived from the dipole field components assuming feed-down from the quadrupole [4], and could be measured reproducibly to on each current plateau of several minutes duration. Center position dX (direc- tion of the first normal quad pole) versus current is shown in Figs.…”

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 and is conductively cooled from the cryomodule LHe supply pipe and a helium gas return pipe. The quadrupole generates 36 T integrated magnetic field gradient, has 600 mm effective length, and the peak gradient is 54 T/m. In this paper the quadrupole magnetic, mechanical, and thermal designs are presented, along with the magnet fabrication overview and first test results.

“…Also, studies are being carried out to ensure that the small beam emittances are preserved along the linacs, which will require micron-level beam position resolution and stability of the quadrupole magnet centers over time and with field strength changes. Table IV summarizes their design requirements [46].…”

The International Linear Collider is planned as the next energy-frontier electron-positron accelerator. The main linacs of the collider are based on superconducting radio-frequency cavity technology, and will accelerate electron and positron beams up to 250 + 250 GeV at the center-of-mass energy. Based on the Reference Design Report issued in 2007, the ILC Global Design Effort has moved into the Technical Design phase. This paper describes the status of the design, R&D efforts, and plans of the superconducting RF cavity for the ILC.
