The PREFER (olarization REsearch for Fusion Experiments and Reactors) collaboration was born to address the know-how in different fields and techniques to the challenging bet on fusion energy production with polarized fuel. Efforts are focused on a variety of tasks and objectives, which are under the responsibility of different institutes.

As part of a Spin Polarized Fusion (SPF) program, polarized $^7$LiD pellets are being developed at Jefferson Lab (JLAB) for testing the survivability of nuclear polarization in a ∼100 million Kelvin fusion plasma. With polarized fuels in a tokamak, the cross section can increase by 50%, and the power gain of a large-scale fusion reactor, such as ITER, by 75%. However, this...

The challenging magnetic problem of producing internal fields in compact spaces can be solved by high temperature superconducting bulk materials, such as MgB$_2$, which are promising tools for trapping fields around polarized substances, while shielding out external fields, as required for fundamental physics studies in scattering experiments.
They are also of great interests, as they allow...

The AI-Optimized Polarization project seeks to develop experimental control applications for polarized targets and beams at Jefferson Lab using AI/ML. This talk will focus on two on-going efforts involving a cryogenic polarized target and a linearly-polarized photon beam. Firstly, cryogenic targets, such as those used in Halls B and C (and approved for Hall D), are complex systems that are...

has been pivotal in solid-state polarized target experiments within Nuclear and
High Energy Particle physics. Phase-sensitive detection using a Liverpool Q-
meter is conventionally employed for monitoring polarization during scattering
experiments. Yet, when operating outside of designed operational parameters,
