TL;DR: In this paper, a modular luminescence lifetime imaging system (MOLLI) was developed, which enables the imaging of luminecence lifetimes in the range of 1 ms to 1 s. The system can easily be adapted to different experimental applications.

TL;DR: In this paper, an overview of all conducted HTS current leads acceptance tests is given, and the results for the different CLs are summarized and compared to the specifications. But the main parts of each acceptance test are the determination of the heat load at the 4.5-k level, of the necessary 50-k He mass flow rate through the heat exchanger as well as the simulation of a loss of flow accident of the 50-K mass flow at full current (18.2kA).

TL;DR: In this article, an overview of the manufacture and acceptance tests of the high-temperature superconductor (HTS) current lead is given. But the main parts of the acceptance test are the determination of the heat load at 4 K and the 50 K He mass flow rate through the heat exchanger as well as the simulation of a loss of flow accident.

TL;DR: The Karlsruhe Institute of Technology (KIT) is responsible for design, production and test of the High Temperature Superconductor (HTS) current leads for the stellarator Wendelstein 7-X (W7-X) as discussed by the authors.

TL;DR: The setup of the CuLTKa facility is described from cryogenic, electrical and process control point of view and will highlight the design of particular technical aspects.
