The UK contribution to achieving the ultra-low background conditions required inside the detectors of the SuperNEMO experiment are described. A dedicated facility has been established for the screening and selection of materials through gamma ray spectroscopy using germanium detectors. Initial results from two detectors are shown. The radon level inside the SuperNEMO detector must be less than 150 μBq m3 in order to achieve the target sensitivity. A Radon Concentration Line (RnCL) has been developed capable of measuring radon levels in large gas volumes down to 5 μBq m3, improving on standard state-of-the-art radon detectors by 3 orders of magnitude. The development, commissioning and first measurements of radon content using the RnCL are also presented.

A portion of the Muon g-2 Storage Ring electric system, which provides vertical beam focusing, exhibited an unexpected time dependence that produced a characteristic evolution of the stored beam during Run-1 of the Muon g-2 Experiment at Fermilab (E989). A method to reconstruct the Run-1 electric guide fields has been developed, which is based on a numerical model of the muon storage ring and optimization algorithms supported by COSY INFINITY. This method takes beam profile measurements from the Muon g-2 straw tracking detectors as input, and it produces a full reconstruction of the time-dependent fields. The fields can then be used for the reproduction of detailed beam tracking simulations and the calculation of ring lattice parameters for acceptance studies and systematic error evaluations.

The Proton EDM Experiment (pEDM) is the first direct search for the proton electric dipole moment (EDM) with the aim of being the first experiment to probe the Standard Model (SM) prediction of any particle EDM. Phase-I of pEDM will achieve \\(10^{-29} e\\cdot\\)cm, improving current indirect limits by four orders of magnitude. This will establish a new standard of precision in nucleon EDM searches and offer a unique sensitivity to better understand the Strong CP problem. The experiment is ideally positioned to explore physics beyond the Standard Model (BSM), with sensitivity to axionic dark matter via the signal of an oscillating proton EDM and across a wide mass range of BSM models from \\(\\mathcal{O}(1\\text{GeV})\\) to \\(\\mathcal{O}(10^3\\text{TeV})\\). Utilizing the frozen-spin technique in a highly symmetric storage ring that leverages existing infrastructure at Brookhaven National Laboratory (BNL), pEDM builds upon the technological foundation and experimental expertise of the highly successful Muon $g$$-$$2$ Experiments. With significant R\\&D and prototyping already underway, pEDM is preparing a conceptual design report (CDR) to offer a cost-effective, high-impact path to discovering new sources of CP violation and advancing our understanding of fundamental physics. It will play a vital role in complementing the physics goals of the next-generation collider while simultaneously contributing to sustaining particle physics research and training early-career researchers during gaps between major collider operations.

We describe a proposal to search for an intrinsic electric dipole moment (EDM) of the proton with a sensitivity of \\targetsens, based on the vertical rotation of the polarization of a stored proton beam. The New Physics reach is of order \\(10^~3\\)TeV mass scale. Observation of the proton EDM provides the best probe of CP-violation in the Higgs sector, at a level of sensitivity that may be inaccessible to electron-EDM experiments. The improvement in the sensitivity to \\(\\theta_{QCD}\\), a parameter crucial in axion and axion dark matter physics, is about three orders of magnitude.

Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well beyond those reached directly at high energy colliders. Discrimination between different physics models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss the current status and prospects in the near future for a compelling suite of such experiments, along with developments needed in the encompassing theoretical framework.

The Front Ranges and Main Ranges in the Kananaskis area of the southern Canadian Rocky Mountains were profoundly influenced by Paleozoic tectonics. The Cambrian-Ordovician McKay Group is over 3000 meters thick and forms 4 outer-detrital-belt grand cycles. Two of these grand cycles have no counterpart in correlative rocks elsewhere in the southern Canadian Rockies and were preserved by Ordovician tectonics across an eastern embayment in a lower Paleozoic structural zone, the Kicking Horse Rim. Shale in the overlaying Glenogle Formation is replaced eastward by a shallow-water succession of quartzite and dolomite (the Tipperary Formation). The Middle Ordovician Skoki Formation disconformably overlies the Tipperary Formation and this disconformity is reflected in Glenogle shales by a missing graptolite zone and coarser clastics. 600 meters of strata are truncated by an angular uncomformity below the Upper Ordovician Beaverfoot Formation. The Beaverfoot Formation overlies Ordovician diatremes and at least one Ordovician normal fault. Middle Devonian strata angularly overlie a second set of diatremes. Structures in the Main Ranges consist of tight, dominantly chevron-style folds, thrust faults that cut through the overturned limbs of folds, and normal faults that truncate earlier thrust faults. The intensity of spaced cleavage, indicative of significant pressure solution, changes within the stratigraphic column and is inversely proportional to fracture intensity. Deformation mechanisms are partitioned as a function of depth in the stratigraphic column and reflect inhomogeneous shortening within trust sheets. Structural continuity exists between the Main Ranges and Front Ranges subprovinces. The Bull River Thrust extends into the region from the south but dies out. The eastern Main Ranges represent a structural culmination in the Bourgeau Thrust sheet of the Front Ranges. Disharmonic folding between the Devonian and Ordovician sequences within the Bourgeau Thrust sheet is inferred from down-plunge projection. Inhomogeneous shortening within the Bourgeau thrust sheet allows for the up-dip conservation of fault displacement. The unusually thick Paleozoic sequence carried in the hanging wall of the Bourgeau Thrust cannot be balanced with any equivalent sequence in the footwall. The trajectory of the Bourgeau Thrust passed along the ancient Kicking Horse Rim and the thrust juxtaposes two unique Paleozoic sequences.

Having been permitted through the courtesy of the BOOK REVIEW to express myself concerning Lowell's literary allusions, and, moreover, having had the good fortune to find my humble opinion sustained by some exceedingly able and pertinent remarks editorial, I should much like to be allowed to add a final word or two.

Our highly esteemed brother, James Mott, of Philadelphia, in a letter recently received, furnishes us with the following interesting account:
