This equipment is part of the larger facility that takes a picture of the explosion that triggers the nuclear reaction.

Test for a nuclear bomb with the atomic explosion is prohibited.  The lab devised a way to test the bomb without having a usual blast by using subcritical nuclear mass, then simulated the rest with a computer what would happen when critical nuclear mass was used

The computers the lab used previously.

A modern nuclear bomb.

Los Alamos Lab does much more than the atomic bomb research and test.
