RACER IV

RACER IV was a component of some of the first hydrogen bombs made by the United States during the 1950s.[2]: 196 : 236  Its reliability issues ruled it out as a primary in the emergency capability devices, whose proper operation was imperative.Inside the capsule, the TOM initiator was nested with a caltrop-like steel mounting.[2]: 196 Concomitant to stringent yield predictability and reproducibility requirements, the design's bizarre yields meant that as a primary, RACER did not furnish the proper quantity and strength of x-rays and neutrons to implode and initiate respectively the secondary stage.[2]: 317  The unpredictable neutron flux had a catastrophic impact to the TX-22 program, as the MORGENSTERN prototype fizzled and its sister project RAMROD was canceled due to the poor performance of RACER IV.
