Description

The Future Circular Electron-Positron Collider (FCC-ee) is a proposed next-generation particle accelerator, planned as the first stage of the larger Future Circular Collider project at CERN. It is an electron-positron collider designed to be a precision instrument for studying fundamental physics.

The PSI Positron Production (P$^{3}$) is the planned proof-of-principle experiment for the FCC-ee positron source. The main goal of this experiment is to test new technology and validate the envisioned positron production scheme. To this end, a prototype of the FCC-ee positron source will be hosted at the SwissFEL facility at the Paul Scherrer Institute in Switzerland.

A dedicated bunker has been built inside the SwissFEL tunnel, and the experimental components are being installed.
Simulations have been performed with the FLUKA.CERN Monte Carlo code to dimension the P$^{3}$ bunker and local shielding elements. Calculations have been repeated for various target models since different target options will be tested.

This contribution briefly describes the ingredients of the P$^{3}$ experiment and details the dedicated bunker and the local shielding. It shows the expected dose rate distribution outside the P$^{3}$ bunker. The foreseen activation is also discussed.
