Stability of Superconducting Wire in Magnetic Field

A fundamental experiment was carried out to study the motion of superconducting wire under the influence of electromagnetic force. Experiments were conducted at 4.2 K by varying the experimental conditions such as applied tension to test superconducting wire, insulating material used at the interface of superconducting wire and base material. The experimental method and the test results are rep...

Development of Instrumentation for Magnetic Field Measurements of 2m Long Superconducting Undulator Coils

Precise measurements of the magnetic properties of conventional, i.e., permanent magnet based insertion devices has undergone tremendous improvements over the past 10 to 15 years and initiated a new era in synchrotron light sources worldwide. A similar breakthrough is now necessary in the field of superconducting insertion devices. In this contribution we describe the planned instrumentation to...

Low-cost field goniometer for multiangular reflectance measurements

A low-cost field goniometer was constructed for multiangular reflectance measurements using a spectral radiometer. The goniometer consists of a circular base made of plywood approximately 4 m in diameter. A rotating arch carries a sled with the radiometer, which can be positioned at any angle relative to the test object at the center of the goniometer. Data from the radiometer are downloaded to...
