| 内容記述 | The effect of 1-MeV electron irradiation, up to a total dose of 5.7 x 10 to the 17th electrons/sq cm at room temperature on YBa2Cu3O(x) was investigated using gold bead contacts made by the melting technique. The superconducting transition temperature Tc, the critical current density Jc at 77 K, the normal-state resistivity, and the contact resistance for gold bead contacts were measured as a function of fluence on the same samples without disturbing the contacts. Tc remained constant at 91 K, and Jc at 77 K remained constant around 90 A/sq cm. The normal-state resistivity increased systematically by about 15 percent for the total dose. Finally, the surface contact resistance at 77 K remained less than 4.2 microohm sq cm throughout the radiations. These studies took place over an 8-month period, and subsequent measurements indicate that the results are definitely due to radiation effects and not aging effects. It is concluded that the superconductor YBa2Cu3O(x) with gold bead contacts would perform well in a space environment of electron irradiation. |
