TMD: The Orientational Shadow Method: Proton Shadow Imaging (Extended Experimental Concept)

This work presents an extended experimental concept of the orientational shadow method, focusing on the direct detection of the proton’s orientational deficit within the mechanical framework of TMD (Triadic Mesh Dynamics). While the original version of the method targeted slow systems with low internal frequencies, this extended concept develops a realistic experimental strategy for proton shadow imaging using currently available technologies. The proposed setup combines a collimated proton beam, a transverse laser beam, and an array of superconducting detectors with controlled picosecond–femtosecond time offsets. By exploiting spatial shadow signatures, stroboscopic undersampling, and multi‑detector time multiplexing, the method enables phase‑resolved reconstruction of the proton’s orientational shadow without requiring direct femtosecond temporal resolution. This work outlines the principles, experimental arrangement, technological limits, and reconstruction techniques that together form a feasible route toward the first direct measurement of the proton’s orientational shadow — a potential signature test of TMD in the domain of hadronic physics.
