However, currently known high-temperature superconductors are brittle ceramics that are expensive to manufacture and not easily formed into wires or other useful shapes. [4] Therefore, the applications for HTS have been where it has some other intrinsic advantage, e.g. in: low thermal loss current leads for LTS devices (low thermal conductivity),
The table below shows some of the parameters of common superconductors. X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.
ReBCO superconductors have the potential to sustain stronger magnetic fields than other superconductor materials. Due to their high critical temperature and critical magnetic field, this class of materials are proposed for use in technical applications where conventional low-temperature superconductors do not suffice.
Ceramic superconductors cannot be bolted or welded together to form superconducting junctions. Ceramic superconductors must be cast in their final shape when created. This may increase production costs. [citation needed] Ceramic superconductors can be more easily driven out of superconductivity by oscillating magnetic fields.
BSCCO superconductors already have large-scale applications. For example, tens of kilometers of BSCCO-2223 at 77 K superconducting wires are being used in the current leads of the Large Hadron Collider at CERN [10] (but the main field coils are using metallic lower temperature superconductors, mainly based on niobium–tin).
Metal alloy superconductors can also exhibit type-II behavior (e.g., niobium–titanium, one of the most common superconductors in applied superconductivity), as well as intermetallic compounds like niobium–tin. Other type-II examples are the cuprate-perovskite ceramic materials which have achieved the highest superconducting critical ...
High temperature superconductors have been investigated for SNSPDs [45] [46] with some encouraging recent reports. [47] [48] SNSPDs have been created from magnesium diboride with some single photon sensitivity in the visible and near infrared. [49] [50] There is considerable interest and effort in scaling up SNSPDs to large multipixel arrays ...
The motivation for using superconductors in RF cavities is not to achieve a net power saving, but rather to increase the quality of the particle beam being accelerated. Though superconductors have little AC electrical resistance, the little power they do dissipate is radiated at very low temperatures, typically in a liquid helium bath at 1.6 K ...
