Description
Beam profile diagnostics will play a crucial role in the commissioning and efficient operation of the electron-positron Future Circular Collider (FCC-ee).
This talk presents the current status of feasibility studies for the transverse diagnostics systems. Non-invasive techniques are essential to prevent beam perturbations during regular physics operation.
As is customary in high-energy lepton colliders, transverse diagnostics will primarily rely on synchrotron radiation. Given the picometer-level emittances expected at FCC-ee,
diagnostics in the x-ray domain are the most suitable choice, and the optimal locations for transverse beam monitoring have already been identified in the present design of the collider lattice.
Pinhole cameras have been selected as the baseline solution, providing robust and precise beam size monitoring from the early commissioning stages.
Additionally, an advanced technique based on Heterodyne Near-Field Speckle interferometry is being explored as a potential method to enhance the accuracy of synchrotron radiation-based diagnostics.
Finally, an outlook on the next steps toward the Technical Design Report will be presented.
