Traditional medical imaging systems depend on X-ray absorption differences among tissues to distinguish them [1]. While effective at separating bones from other biological structures, they struggle to differentiate between different types of soft tissue (e.g., normal and tumor cells) [2]. The refractive properties of tissues, however, can induce X-ray phase shifts that are highly sensitive to...

Ion therapy with protons or heavier particles like helium or carbon enables highly precise and conformal dose delivery within the target volume, especially in comparison to photon-based radiation therapy. However, this precision is associated with a higher treatment sensitivity to anatomical and positional changes of the patient [1]. To detect such changes, our group developed a monitoring...

Despite significant advancements, solar neutron detection remains hindered by several key limitations. The short lifetime of free neutrons (15 min) causes the detectable flux to drop sharply with distance from the Sun, making proximity to the source essential. Existing space-based instrumentation must additionally contend with cosmic-ray and spacecraft-induced backgrounds, while being...
