EXCITATION TRANSFER IMPLEMENTATIONS FOR NON-EXPONENTIAL DECAY OF RADIOACTIVE SPECIES
A method of excitation transfer to a radioactive source is provided, the radioactive source having a natural radioactive decay rate. The method includes: energizing a stimulatory device coupled to a radioactive source, thereby exciting the radioactive source to decay at an enhanced rate that is higher than the natural radioactive decay rate. An excitation transfer apparatus includes: a support element; a radioactive source mounted on the support element, the radioactive source having a natural radioactive decay rate; a stimulatory device coupled to the support element; and a driver operatively connected to the stimulatory device to energize the stimulatory device, wherein upon energization, the stimulatory device excites the radioactive source which thereby decays at an enhanced rate that is higher than the natural radioactive decay rate.

INDUCED NUCLEAR EXCITATION TRANSFER
An excitation transfer in a nuclear state is energetically induced. The excitation transfer may be induced by heating a structure to which a nuclear species is mechanically coupled. The heating may be applied as a triangular heat pulse. The heating may generate a stress effect in the structure. The stress effect may produce vibratory phonons. The excitation transfer may include up-conversion. The excitation transfer may include radioactive decay. The decay rate of a radioactive species may be increased to a rate higher than the natural half-life of the radioactive species. Energy may be harnessed from decay of the radioactive species. A decay product having industrial or medical use may be rapidly produced. The decay rate of the radioactive species may be lowered to reduce emissions for safe storage or transportation.
Compositions for Nuclear Reactions and for Fuel
In accordance with one embodiment, lower energy photons are combined into a higher energy photon, a phat, by a shift in equilibrium from plasma toward condensing atoms. Phats are an ingredient for new compositions of matter and for nuclear reactions. Many of these compositions of matter are between a chemical and a nuclear scale. A self-assembled reactor is described at this scale. Also, fuels are produced that are high energy activated compositions of matter. Some activated compositions of matter can cause various nuclear reactions. A sequence is described for generalized chemical/nuclear steps. The nuclear reactions which occur include: photodisintegration, neutron absorption, accelerated nuclear decay of radioactive isotopes, and fusion of various combinations of elements.

Method and system for controlling ion beam pulses extraction
The embodiments of the present disclosure relate to a method and system for controlling the extraction of ion beam pulses produced by a synchrocyclotron. The synchrocyclotron comprises electrodes configured to be placed in a magnetic field. An alternating voltage is applied between the electrodes, and the frequency of the alternating voltage is modulated in a cyclic manner. In other embodiments, the method further comprises the steps of starting an acceleration cycle of the synchrocyclotron, generating a reference signal when the modulated frequency reaches a predefined value, communicating the time, at which the reference signal is generated, to the beam control elements, assessing one or more status parameters of the one or more beam control elements, and cancelling or proceeding with the extraction of the beam pulse depending on the results of the assessment.
