/ Vallis, Nicolas (PSI, Villigen ; Ecole Polytechnique, Lausanne) ; Craievich, Paolo (PSI, Villigen) ; Schaer, Mattia (PSI, Villigen) ; Zennaro, Riccardo (PSI, Villigen) ; Auchmann, Bernhard (PSI, Villigen) ; Besana, Maria Ilaria (PSI, Villigen) ; Duda, Michal (PSI, Villigen) ; Fortunati, Reto (PSI, Villigen) ; Garcia Rodrigues, Henrique (PSI, Villigen) ; Hauenstein, Dominique (PSI, Villigen) et al.
The PSI Positron Production experiment, known as $\text{P}^{3}$ or $\textit{P-cubed}$, is a proof-of-principle positron source and capture system that can greatly improve the state-of-the-art positron yield. The $\text{P}^{3}$ project is led by the Paul Scherrer Institute in Switzerland, and addresses the long-standing challenge faced by conventional injector facilities to generate, capture, and damp the emittance of high-current positron beam, which is a major limiting factor for the feasibility of future electron-positron colliders.

Improving future designs by learning from radioactive waste-management experiences
/ Grenard, Jean-Louis (speaker) (CERN)
As CERN operates its accelerator complex with a high-energy charged particle beam, the interaction of this beam with various systems designed to guide, shape, absorb and produce secondary particles, results in production of radioactive components and the activation of nearby equipment.
Consequently, the components need to be safely managed and handled once they are removed from the accelerator complex, either to store or safely and sustainably dispose them as waste. Host-state requirements dictate the specific packaging type, size, composition, and activity levels that these packages shall have.
Moreover, ALARA principles must be included in the design processes for new beam intercepting devices and target production areas, to reduce exposure of personnel to ionizing radiation and to optimally exploit these installations. [...]

Investigating the feasibility of delivering higher intensity proton beams to ECN3 at the CERN SPS North Area
/ Fraser, M A (CERN) ; Brugger, M (CERN) ; Ahdida, C (CERN) ; Arduini, G (CERN) ; Arrutia Sota, P A (CERN) ; Bartosik, H (CERN) ; Bernhard, J (CERN) ; Calviani, M (CERN) ; Colinet, A (CERN) ; Esposito, L S (CERN) et al.
Initiated through the Physics Beyond Colliders (PBC) Study Group there is a strong interest from the scientific community to exploit the full intensity potential of the Super Proton Synchrotron (SPS) at CERN for Fixed Target physics experiments before the end of this decade. With the ECN3 cavern in the North Area (NA) identified as a suitable candidate location for a future high-intensity experimental facility compatible with a large variety of experiments, the new PBC ECN3 Beam Delivery Task Force was mandated to assess the feasibility of delivering a slow extracted beam of up to 4x10^19 protons per year at 400 GeV.
