Abstract: Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, for beam shaping for large aspect ratios with a single cylindrical lens. In some aspects, a QIP system includes a laser source, a cylindrical lens, and an ion trap. The laser source produces a Gaussian laser beam. The cylindrical lens is aligned with at least a portion of the laser beam and shapes the laser beam into a beam having an anamorphic shape. The ion trap includes a plurality of trapped ions addressable by the beam. The cylindrical lens orients the beam relative to the ion trap such that a fast axis of the beam is aligned with an axis of the plurality of trapped ions, and a slow axis of the beam is traverse to the plurality of trapped ions.

Abstract: A target carrier assembly includes a housing, a target, and a collimator. The housing includes a collimator compartment and a target compartment divided by a vacuum window foil, the collimator being removably disposed within the collimator compartment, and the target being disposed within the target compartment. The collimator compartment is attached to a cyclotron beam line in the irradiation position, and the target compartment is in fluid communication with a cooling fluid supply line and a cooling fluid return line in the irradiation position. The target is cooled by the cooling fluid from the cooling fluid supply line. The collimator directs a particle beam from the cyclotron beam line to irradiate the target and includes a beam entry diameter and a beam exit diameter. The collimator is in thermal contact with the collimator compartment.

Abstract: A sample inspection system contains a source of electromagnetic radiation and an apparatus that includes a beam former, a collimator and an energy resolving detector. The beam former is adapted to receive electromagnetic radiation from the source to provide a polygonal shell beam formed of at least three walls of electromagnetic radiation. The collimator has a plurality of channels adapted to receive diffracted or scattered radiation at an angle. The energy resolving detector is arranged to detect radiation diffracted or scattered by a sample upon incidence of the polygonal shell beam onto the sample and transmitted by the collimator.
