Transition edge sensors (TES) play a key role in current projects of future X-rays space
telescopes as are foreseen as detectors for the focal plane instrument. In order to full exploit
their sensitivity in the space environment, they need an active cryogenic anticoincidence
detector (CryoAC) to reject the background due to cosmic charged particles. As signal given by
the interaction of...
The first step towards high critical currents in Bi-2212 wires was the comprehension that the supercurrent is blocked over long lengths by filament-diameter bubbles growing from the porosity of the powders during the partial melting phase. The Over Pressure (OP) process led to the realization of dense Bi-2212 wires with a $J_E$ performance far beyond the minimum application requirements, but...
