Claim 0:
1. A method of manufacturing a lead assembly of a cryogenic system, comprising:
developing a first three-dimensional (3D) model of a heat exchanger having a first end and a second end opposite the first end, the heat exchanger including a plurality of channels extending longitudinally through the heat exchanger from the first end to the second end, the plurality of channels forming a plurality of thermal surfaces within the heat exchanger, the heat exchanger having a transverse cross section;
determining a thermal performance of the heat exchanger according to the first 3D model;
modifying the first 3D model based on the determined thermal performance to generate a second 3D model of the heat exchanger, the second 3D model having both a reduced solid area of the cross section and increased thermal surfaces of the plurality of thermal surfaces relative to the first 3D model such that a temperature at the second end of the heat exchanger according to the second 3D model is at or below a critical superconducting temperature of a high temperature superconductor (HTS) strip during ramping of the cryogenic system;
additively manufacturing the heat exchanger using an electrically-conductive and thermally-conductive material according to the second 3D model;
providing a HTS assembly that includes the HTS strip; and
connecting the HTS assembly to the heat exchanger at the second end of the heat exchanger.
