  • Publication number: 20240087868
    Abstract: A method is provided for controlling a multi-pole charged particle transmission device having rods spaced apart radially about a central axis extending from a particle inlet at one end of the device to a particle outlet at an opposite end. An AC voltage source is controlled to apply an AC voltage having a frequency, a peak amplitude, and a waveform shape to the charged particle transmission device, and a set of charged particles is passed through the device under such conditions. The AC voltage source is then controlled to change at least one of the frequency, peak amplitude or shape of the AC, and another set of the charged particles is then passed through the charged particle transmission device under such conditions.

  • Patent number: 8668406
    Abstract: The invention facilitates provision of a point-to-point cable connection between first and second points separated by an extended span of water including a first region of shallow water and a second region of relatively deep water. A plurality of ducts are provided from the first point through the first region of the extended span to an offshore termination point between the first and second points. Preferably, the ducts are buried in the seabed to prevent damage. At least one first cable is placed in one of the plurality of ducts to provide a connection between the first point and the offshore termination point. A second cable from the second point is received at the offshore termination point. The first cable is connected to the second cable at the offshore termination point to create the point-to-point cable connection. In one embodiment, the offshore termination point is located on the continental shelf near the transition to deep water.
