Abstract
It has been recently observed that heavily irradiated silicon detectors, no longer functional at room temperature, dramatically improves when operated at temperatures below 130 K. This is often referred to as the "Lazarus effect". The results presented here show that cryogenic operation represents a new and reliable solution to the problem of radiation tolerance of silicon detectors.
