    摘要: Novel compositions and morphologies of carbon nanoflakes are described, as well as methods for making carbon nanoflakes using a radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) process. Acetylene is used as a CVD source gas. By utilizing high concentrations of acetylene in the CVD source gas at relatively low temperatures, carbon nanoflake growth rate and robustness are improved, and the resulting carbon nanoflakes have enhanced height uniformity.

    摘要: Techniques for particle beam therapy include receiving a target region inside a subject for particle therapy, a minimum dose inside the target region, and a maximum dose inside the subject but outside target region. Multiple beam axis angles are determined, each involving a grantry angle and a couch position. Multiple spots within the target region are determined. For each beam axis angle a pristine particle scan beam (not coaxial with any other particle scan beam) is determined such that a Bragg Peak is directed to a spot, and repeated until every spot is subjected to a Bragg Peak or an intersection of two or more such pristine scan beams. Output data indicating the pristine beamlets is stored for operation of a particle beam therapy apparatus.
