Description
The Bonn Isochronous Cyclotron provides light ion beams of a charge-to-mass ratio Q/A >= 1/2 with kinetic energies ranging from 7 to 14 MeV/A to five experimental sites.
To improve operation reliability, the cyclotron's electrostatic extraction septum is upgraded using components, manufactured by laser-powder bed fusion (L-PBF).
The new copper septum blade holder reduces thermal load on the blade and the integrated cooling system's leak rates to the vacuum.
Also, a new beam diagnostic section for the future ion beam analysis setup in Beamline D is under construction, comprising a secondary electron monitor, a Faraday cup (FC) and a beam screen (BS).
Both, FC and BS, are made from aluminium using L-PBF and are pneumatically retractable.
Cooling is provided through coaxial water tubes, integrated into the pneumatic rods.
Here, progress of the septum upgrade will be reported and details of the new diagnostic section will be provided.
