Description
The Cryogenic Current Comparator (CCC) is a non-interceptive beam diagnostic device for measuring low-intensity ion beams down to the nanoampere range. This work focuses on developing a compact CCC system for CRYRING@ESR at GSI, where installation space inside the ring is limited. A key constraint is integration close to a correction solenoid and dipole magnet, where magnetic perturbations can affect the SQUID readout.
The study investigates a compact CCC design adapted to the mechanical, cryogenic, and magnetic constraints of CRYRING. The short detector length and pickup-coil design directly influence current resolution, which has to be investigated in detail. Special attention is given to detector positioning, magnetic shielding, vibration reduction, and thermal stability, since these factors also affect resolution and reliability. Concerning thermodynamic properties a CCC Simulation framework is being developed to estimate the cryogenic standing time, heat loads, helium consumption and operational stability of the compact system.
The goal is to optimize the compact CCC geometry and cryogenic support system for reliable operation in CRYRING, future nanoampere-level beam current measurements and compact CCC diagnostics for FAIR.
