Query: Design of a Canted-cosine-theta orbit corrector for the High Luminosity
  LHC   The High Luminosity LHC requires dipole orbit correctors grouped in double
aperture magnet assemblies. They provide a field of 3.1 T at 100 A in an
aperture of 70 mm. The current standard design is a classical cosine-theta
layout made with ribbon cable. However, the electric insulation of the ribbon
cable is not radiation-resistant enough to withstand the radiation load
expected in the coming years of LHC operation. A new design, based on a
radiation-resistant cable with polyimide insulator, that can replace the
existing orbit correctors at their end-of-life, is needed. The challenge is to
design a magnet that fits directly into the existing positions and that can
operate with the same busbars, passive quench protection, and power supplies as
existing magnets. We propose a self-protected canted-cosine-theta (CCT) design.
We take the opportunity to explore new concepts for the CCT design to produce a
cost-effective and high-quality design with a more sustainable use of
resources. The new orbit corrector design meets high requirements on the field
quality while keeping within the same mechanical volume and maximum excitation
current.
  A collaboration of Swedish universities and Swedish industry has been formed
for the development and production of a prototype magnet following a concurrent
engineering (CE) methodology to reduce the time needed to produce a functional
CCT magnet. The magnet has a 1 m long CCT dipole layout consisting of two
coils. The superconductor is a commercially available 0.33 mm wire with
polyimide insulation in a 6-around-1 cable. The channels in the coil formers,
that determine the CCT layout, allow for 2 x 5 cable layers. A total of 70
windings makes that the coil current can be kept below 100 A. We will present
the detailed design and preliminary quench simulations.
