The high-luminosity LHC upgrade (HL-LHC) aims to increase integrated luminosity by a factor of ten compared to the present LHC. To focus the beam more strongly towards the interaction point, superconducting magnets in the insertion regions must be upgraded. In the framework of CERN-KEK collaboration, KEK is in charge of developing a large150-mm-aperture beam separation dipole (MBXF). The field...
In the frame of the high-luminosity upgrade project (HL-LHC) of CERN for the Large Hadron Collider (LHC), a new double aperture beam orbit corrector magnets will be installed near the recombination dipole (D2). These 2.2 m long NbTi dipoles are built with the “canted cosine theta” (CCT) technique. The two independently powered apertures are oriented such that their field vectors are...
The first prototype of the short orbit corrector MCBXFB for the upgrade of the LHC has been fabricated at CIEMAT, in collaboration with CERN, in the framework of the HL-LHC project. It consists of two nested dipoles, with an aperture of 150 mm and physical length of 1.5 m.
A first cold test was performed without the outer dipole coils, which were replaced by a support structure to align the...
For the HL-LHC project, a 90 mm double aperture NbTi quadrupole magnet is being developed as an option to replace the 70 mm aperture LHC quadrupole MQY. This cos(2theta) magnet has an operating gradient of 120 T/m at 1.9 K and a magnetic length of 3.67 m. A single aperture short model magnet with a magnetic length of 1.2 m at 1.9 K has been designed at CEA and is being manufactured in...
The new and unique accelerator complex FAIR is currently under construction at GSI, Darmstadt, Germany. FAIR, the Facility for Antiproton and Ion Research, will investigate matter behavior inside stars, antimatter as well as biophysics questions using its variety of physics experiments. The core of this facility is the 1100 m circumference heavy ion synchrotron SIS100 featuring 100 T/m...
A new international facility for antiproton and ion research (FAIR) is currently under construction in Darmstadt, Germany. The SIS100 heavy ion synchrotron, with a magnetic rigidity of 100 Tm, will provide the high intensity primary beam required for different research experiments. The synchrotron is composed of 415 fast cycling superconducting magnets from which 108 are dipole magnets. The...
The Jefferson Lab Electron Ion Collider (JLEIC) is a proposed new machine for nuclear physics research. It uses the existing CEBAF accelerator as a full energy injector to deliver 3 to 11 GeV electrons into a new electron collider ring. An all new ion accelerator and collider complex will deliver up to 200 GeV protons. The machine has luminosity goals of 10^34 cm^-2 sec^-1. The whole...
