THC01 | SHE Factory: Cyclotron Facility for Super Heavy Elements Research | 305 |
|
||
The synthesis of heavy and the heaviest elements and the study of their nuclear and chemical properties are of highest priority in the basic research programme of the Flerov Laboratory of Nuclear Reactions. The synthesis of super heavy elements (SHE) with atomic numbers 113-118 has been achieved in the 48Ca-induced reactions. The International Unions of Pure and Applied Physics (IUPAP) and Chemistry (IUPAC) recognized the priority of Dubna in the discovery of elements 114-118. The seventh period of the Periodic Table has been completed. In accordance with the development program, the first in the world SHE Factory was built at the Laboratory on the basis of the new DC280 cyclotron which was commissioned in 2019. DC-280 has to provide intensities up to 10 pmkA for ions with atomic masses over 50. The main task of the Factory is the synthesis of new chemical elements with atomic numbers 119 and higher, as well as a detailed study of the nuclear and chemical properties of previously discovered superheavy elements. The Factory are being equipped with target materials, new separators and detectors for the study of the nuclear, atomic and chemical properties of the new elements. | ||

THC02 | First Beams Produced by the Texas A&M University Radioactive-Beam Upgrade | 310 |
|
||
Funding: United States Department of Energy, Grant DE-FG02-93ER40773 The first test beams of radioactive ions produced by the ion-guide-on-line (IGOL) system coupled to the charge-breeding electron-cyclotron-resonance ion source (CB-ECRIS) have been accelerated to high energy by the Texas A&M K500 cyclotron. The radioactive ions were first produced by energetic protons, provided by the K150 cyclotron, impinging on foil targets. Low charge-state ions were then swept by a flow of helium gas into an rf-only sextupole ion guide (SPIG) which transports them into the plasma of the CB-ECRIS. The K500 cyclotron and beam-line transport were tuned with analog beam before tuning the radioactive beam. |

THC03 | Design of Accelerator Mass Spectrometry Based on a Cyclotron | 314 |
|
||
In this paper, we present a cyclotron-based accelerator mass spectrometry system. Conventional AMS systems use tandem accelerators for generating carbon-14 beams. We have developed an ion source, RF buncher, cyclotron, triplet quadrupole, detector and dipole magnet for an AMS system. | ||

THC04 | 3D Printing for High Vacuum Applications | 317 |
|
||
This thesis deals with the manufacture of parts made by 3D printing for high vacuum application. Different components are printed and examined for their vacuum suitability. As shown furthermore, conventionally made standard components can be welded vacuum-tightly to 3D-printed parts, which enables cost-effective production of more complex components, such as a vacuum chamber. In addition, functional components can already be realized during the manufacturing process. The integration of a system of flow channels directly into the wall of a vacuum-chamber is just one example. Thus, such a vacuum-chamber can be heated during evacuation and effectively cooled in later operation. | ||
