1. A power supply for transport of electrical energy from an energy source to a superconducting application or from the superconducting application to the energy source, wherein the power supply is configured to transport an electrical current from a normal circuit comprising the energy source to a circuit comprising at least one superconductor, wherein the energy source is disposed in a warm region and wherein the superconducting application is disposed in a cold region, wherein the power supply has a stack comprising at least two foils, wherein each foil comprises an electrically conductive material configured to transport the electrical energy, wherein each foil has an electrical terminal configured to receive the electrical energy or to release the electrical energy, and wherein each foil comprises a multitude of flow ducts for guiding a fluid stream, wherein the fluid stream comprises a coolant mixture or a gas stream to be cooled or a gas stream to be liquefied, wherein the foils encompassed by the stack have a first flow pathway through the flow ducts which is configured to receive the fluid stream at high pressure level from the warm region, and a second flow pathway through the flow ducts which is configured to receive the fluid stream at low pressure level from the cold region.
