Modulated neutron initiator

In April 1943, Robert Serber had proposed that instead of relying on spontaneous fission, the chain reaction inside the bomb should be triggered by a neutron initiator.
The polonium used in the urchin initiator was created at Oak Ridge and then extracted and purified as part of the Dayton Project under the leadership of Charles Allen Thomas.
