The High-Intensity Heavy-Ion Accelerator Facility (HIAF) is a significant national science and technology infrastructure project, constructed by IMP, to provide primary and radioactive intense beams for nuclear and related research. Large aperture, high-precision, and warm-ion superconducting dipole magnets are extensively utilised to achieve high beam intensities. However, the traditional Hall point measurement platform faces limitations such as magnet volume, measurement environment, and the range of good field regions in the measurement of large dipole magnets, especially huge superconducting dipole magnets, leading to poor operability, low measurement efficiency, and significant errors in secondary positioning accuracy. This paper introduces a new magnetic field mapping measurement system, which introduces ultrasonic motors capable of operating under strong magnetic fields (<7T), and can realize portable, efficient and high-precision magnetic field measurement. After system debugging, the SRing dipole magnet prototype was measured. The system's accuracy and efficiency were verified through comparison with traditional Hall probe measurement systems. On this basis, magnetic field distribution and integral excitation curve measurements of all 11 HFRS warm-iron superconducting dipole magnets and 3 HFRS anti-irradiation dipole magnets were carried out and completed, achieving the testing objectives.

A Theory of Gravity Based on Dimensional Perturbations of Objects in Flat Spacetime
William Northcutt
A covariant classical theory of gravity is given assuming absolute flat spacetime and the strong equivalence principle (SEP). It is shown that adherence to these postulates requires that the gravitational field “dimensionally perturb” all physical objects at a location universally. Such perturbations are referred to as “gravity shifts,” and it is found that all gravitational phenomena may be given in terms of them. Two classes of observers emerge in “gravity shift theory”—“natural observers” using gravity shifted instruments as is, applicable for all presently available observations, and “absolute observers” that correct for the gravity shifting applied to instruments. Absolute observers accurately measure quantities, including the absolute spacetime metric as it actually is. Natural observers do not accurately measure quantities, but their system of measurement is observationally consistent, yielding a curved “natural metric” to characterize spacetime. When a local gravitational system is surrounded by a “background system” with negligible curvature effects, its gravity shifting induces a diffeomorphism applied to the local system, yielding satisfaction of the SEP for natural observers. Using the naturally observed inertial form of physical law in free-fall frames, covariant formulation in all coordinates establishes the natural metric as the universally coupled “gravitational metric” in physical law. The unique field equation determining gravity shifts, and therefore the natural metric, is developed. The resultant bimetric theory is parameterless, complete, and self-consistent. The field equation yields the observed post-Newtonian natural metric and linearizes to the predictive linearized Einstein equation, which, along with SEP satisfaction, results in successful prediction of a wide variety of observed gravitational phenomena. A supplement is provided that extends the range of predictions to include low post-Newtonian order radiation cases, and also the strong-field cases consisting of the properties of black and neutron stars plus any nearby matter and light, where in all cases, the predictions are shown to be consistent with observations.

Energy Renormalization in a Berry Geometrical Phase: Low-Energy Perturbations of the Strong Interaction and the QCD Mass Gap
Mark Gibbons
A Berry geometrical phase is identified in a strongly metastable system containing dynamically responsive clathrate hydrate structures within a crystal-fluid material. High energy degeneracy in the associated chemistry produces local stability and false vacuum conditions that lead to non-extensive and non-additive contributions in the fundamental thermodynamic relation. Application of Ginzburg-Landau theory and the scaling laws reveals a coherence length (3.05 m) and a penetration depth (2.2 m) that characterize a macro-scale dual superconductor. The coherence length describes a magnetic condensate whilst its inverse gives the Higgs mass (0.33 kg) and non-extensive volume changes (± 0.5 l). The penetration depth determines the extent of QCD vacuum suppression whilst its inverse gives an effective vector boson mass (≤ 0.46 kg), resulting in non-additive hyperbolic curvature. Simultaneous emergence of the Ginzburg-Landau superconducting phase transition is consistent with gauge-invariant coupling of the scalar field (≤ 3.6 ks-1) to the Yang-Mills action in QCD. The discovery of an energy gap in the gradient energy term of the system Lagrangian is associated with a critical correlation length (3.05 m) revealed in the transition from a gapped to a gapless superconducting state. Together with the emergence and absorption of the Higgs-like scalar field, a mechanism for describing a renormalized QCD mass gap arises. The phenomena reported are only relevant to a coordinated U(2) symmetry group having scale-invariance across micro- and macro-scale QCD dual superconductivity. Under normal, non-critical conditions the symmetry is broken and separated into SU(2) Abelian condensed matter and SU(3) non-Abelian QCD elements that are effectively isolated. Energy and momentum cannot be transferred across the QCD mass gap and TeV confinement energies dominate where the conservation of energy and momentum are confined to each individual symmetry group. It is proposed that where these symmetries are decomposed and coordinated then the QCD mass gap with associated TeV threshold dissipates.
