Heart transplant on ALMA Correlator

Scientists perform what is effectively a “heart transplant” on the ALMA correlator by installing a custom-built atomic clock powered by a hydrogen maser. This new timepiece uses a process similar to a laser to amplify a single pure tone, cycles of which are counted to produce a highly accurate “tick”.
