Development of superconducting undulator (SCU) technology continues at the Advanced Photon Source (APS). Recently, a new helical SCU has been added to the portfolio of two planar SCUs operating at the APS. The concept of a novel Superconducting Arbitrarily Polarizing Emitter, or SCAPE, has been suggested and tested in a prototype. Work on a long SCU which combines two up to 1.9-m long planar...
INFN is developing at LASA lab (Milano, Italy) the prototypes of five corrector magnets, from skew quadrupole to dodecapole, which will equip the high-luminosity interaction regions of the High Luminosity-LHC (HL-LHC). These magnets are based on a superferric design, which allows a relatively simple, modular and easy to construct magnet. This activity takes place within the framework of a...
The photon beam brightness of synchrotron light facilities is increased by reducing the beam emittance. For the upgrade of the storage ring of the Swiss Light Source (SLS2), the lattice achieving a low emittance foresees longitudinal gradient bending (LGB) magnets producing high peak field values and quasi-hyperbolic field profiles to minimize emittance at locations of radiation.
Two types of...
Future accelerator magnets for producing 20 T and beyond will require using high temperature superconductors (HTS) in combination with low temperature superconductors (LTS). Under the U.S. Magnet development Program (US-MDP), LBNL is exploring the possibility of fabricating HTS insert dipoles based on Bi-2212 conductors, using the Canted-Cosine-Theta (CCT) technology, in order to increase the...
Nb3Sn accelerator magnets are poised to play a key role at improving the luminosity of the Large Hadron Collider (LHC) at CERN by a factor of 5-10, significantly improving its potential for exploring physics beyond the standard model of particle physics. Nb3Sn porotype magnets, based on cosine-theta design, consistently need 10-25 quenches to achieve their best performance whereas a new...
Training is a long-standing problem hindering performance of high-field superconducting accelerator magnets. Proliferation of cracks in the epoxy impregnation and mechanical motion of the conductor in a stick-slip fashion are known to be the most common factors causing premature magnet quenching, and are also responsible for the training. Identifying and understanding those processes is thus...
