Looks like something that would be worth looking into in detail as a potential upgrade for the source. A very relevant question would be the enhancement possible for already approved experiments with the increased luminosity.</div>

The PSI Positron Production (P3 or P-cubed) experiment is a demonstrator for a e+ source and capture system with potential to improve the state-of-the-art e+ yield by an order of magnitude. The experiment is driven by the FCC-ee injector study and will be hosted
in the SwissFEL facility at the Paul Scherrer Institute in Switzerland. This paper is an overview of the P3 design at an advanced stage, with a particular emphasis on a novel e+ capture system and its associated beam dynamics. Additionally, a concept for the
experiment diagnostics is presented, as well as the key points of the ongoing installation works.
<br>
<br>
The remarkable<br>
e+ capture capabilities of P3 are enabled to great extent by the usage of high temperature superconducting<br>
(HTS) solenoid around the target region, as well as a<br>
novel standing wave solution for the RF cavities that<br>
provides a large iris aperture to maximize e+ capture<br>
(see Table II). In addition, a variety of beam diagnostics,<br>
whose goal is to demonstrate such a e+ yield upgrade,<br>
will detect simultaneously the captured e+e- time structure, and measure the bunch charge and energy spectrum<br>
of e+ and e- streams separately <br>
