The cyclotron was invented back in the 1930thand is one of the first resonant accelerator concepts. Cost effective cyclotrons are used today in a broad variety of industrial applications with low and medium beam-powers. However, the resonant acceleration principle and the continuous wave operation ...
2020). Briefly, the [68Ga]GaCl3 is obtained by purifying the proton-bombarded [68Zn]Zn(NO3)2 solution delivered from the cyclotron to an external activity receiving vial. The purification process is based on a three-column purification. The target solution is diluted to ≤ 0.1 M nitric ...
Unfortunately, the co-emission by 44Sc of high-energy γ rays (E γ = 1157, 1499 keV) causes a dangerous increase of the radiation dose to the patients and clinical staff. However, it is possible to produce another radionuclide of scandium—43Sc—having properties similar to 44Sc but...
Methods: First, the tumor dose and volume is used to determine the required energy deposition. For spot scanning, the tumor length along the beam path determines the number of required energy layers. For each energy layer the energy deposition per proton can be calculated from the residual ...

NIIEFA has started manufacturing of a proton cyclotron with energy control in the range of 30–250MeV. The results of developing the system of beam extraction from the cyclotron including a deflector, a system of magnetic channels (125–250 MeV modes), and a stripping device designed for ...
A method for adjusting an energy level of a proton beam of a cyclotron includes providing a target holder assembly with a removable degrader in the path of the proton beam, where the removable degrader can be removed from the path of the proton beam without removal of a target holder ...
