ALS-U is an ongoing upgrade of the Advance Light Source (ALS) at Lawrence Berkeley National Laboratory (LBL). The upgraded ring of the ALS will use a multi-bend-archomat (MBA) lattice, which will allow increasing the brightness of soft x-ray sources

The LHC will incorporate about 7600 superconducting single aperture corrector magnets mounted in the main magnet cold masses. In order to follow up their production, we have designed and built 12 different benches for warm magnetic measurements based

The field strength and homogeneity of all the LHC superconducting magnets were measured as a part of the production control and qualification process that has taken place during the past four years. In addition to field measurements at room temperatu

The LHC insertions will be equipped with individually powered MQM superconducting quadrupoles, produced in three versions with magnetic lengths of 2.4 m, 3.4 m, and 4.8 m. The quadrupoles feature a 56 mm aperture coil, designed on the basis of an 8.8

A full characterization of the magnetic field in warm and cold conditions was performed as a part of the standard test on the LHC 1-m long superconducting dipole models. Furthermore, dedicated measurement campaigns addressed the effect of current cyc

The time decay of field harmonics during current plateaus is a known drawback of superconducting accelerator magnets. The present understanding of this phenomenon refers to a combination of flux creep and of the interaction between the redistribution

Elongated, discontinuous defects provide strong vortex pinning and a corresponding large increase in critical current density in highly anisotropic Tl/sub 2/Ba/sub 2/CaCu/sub 2/O/sub x/ (Tl-2212) thin films. We generate controlled, amorphous damage r

Tl-2212 and Tl-1212 are the two easiest unsubstituted Tl-Ba-Ca-Cu-O superconducting thin films to grow. Both phases exhibit T/sub c//spl ges/95 K, J/sub c/(5 K)>10 MA/cm/sup 2/ and smooth morphologies. We report on the properties of both materials fo

Furnace anneals of TlBa/sub 2/CaCu/sub 2/O/sub x/ thin films at temperatures above 500/spl deg/C cause partial TlO/sub x/ loss. High resolution transmission electron microscopy images reveal nanometer-scale discontinuities (pinched stacking faults) i
