Modes of Acceleration of Ions in a 3-DEE Cyclotron.
The analysis shows that a symmetrical three-dee cyclotron accelerating ions below relativistic velocities has the property that ions of different e/m rations can be accelerated without changing the frequency of the electrical power supplied to the dees or the value of the magnetic field. The energy gain per revolution of the ions which can be accelerated in the various modes are found, considering three identical dees of arbitrary angular widths. For these calculations it has been assumed that a step-function voltage change occurs at each edge of the dees.

The Chelate Process: [Part] 5. Investigation in Horizontal Extractors
The recovery of plutonium has been demonstrated in a laboratory countercurrent horizontal extractor using the TTA process. Using three extractive stages and two washing stages in each step, a recovery of 91 percent has been obtained in the chelation step and a recovery of 99.9+ percent in the de-chelation step. With five extractive stages, recoveries of 94-98 percent have been found for the chelation step.
