  • Publication number: 20250014773
    Abstract: An atomic object confinement apparatus comprising a plurality of electrodes and one or more quasi-direct-current (quasi-DC) circuits. The plurality of electrodes comprise a plurality of radio frequency (RF) rail electrodes arranged to define, at least in part, a periodic array of confinement segments. The plurality of RF rail electrodes are configured such that, when an oscillating voltage signal is applied thereto, the plurality of RF rail electrodes generate a pseudopotential in a form of an array of trapping regions configured to contain at least one atomic object within a respective trapping region of the array of trapping regions. The one or more quasi-direct-current (quasi-DC) circuits are arranged to generate a magnetic field having a selectable magnitude and a selectable direction, such that the generated magnetic field acts on at least one atomic object within the array of trapping regions.

  • Publication number: 20240077046
    Abstract: A centerbody assembly includes a center tube, a forward bulkhead, an aft bulkhead, at least one baffle, and an outer skin. The center tube extends circumferentially about an axial centerline. The center tube extends between and to a first axial tube end and a second axial tube end. The forward bulkhead is mounted to the center tube at the first axial tube end. The aft bulkhead is mounted to the center tube at the second axial tube end. The at least one baffle extends axially from the forward bulkhead to the aft bulkhead. At least the forward bulkhead, the aft bulkhead, or the at least one baffle include one or more thermal beads. The outer skin circumscribes the center tube, the forward bulkhead, the aft bulkhead, and the at least one baffle to form an acoustic cavity radially inside the outer skin.
