摘要：

Irradiation of granular aluminum (g-Al) superconducting strips by betas with energies in the minimum-ionizing range has demonstrated a high detection efficiency. An efficiency of almost 70% was found for 0.5-mu-m wide g-Al strips operating at a temperature of 1.4-1.7 K. This is a very encouraging result for this new concept of a high-resolution tracking detector, which could be used in future colliding-beam accelerators such as the proposed Superconducting Super Collider or other large hadron colliders. As was found earlier with X-ray irradiation, the experiments are accurately described by our thermal-propagation model.
