A converter for generating photons from an electron beam is provided. The converter may include a plurality of converter plates (i) positioned perpendicular to an axis and (ii) arranged sequentially in a direction along the axis from a first converter plate of the plurality of converter plates to a last converter plate of the plurality of converter plates. The first converter plate may be configured to receive an electron beam traveling in the direction along the axis. Further, the first converter plate may have a thickness smaller than a thickness of the last converter plate, wherein a thickness of a particular converter plate is measured along the axis.

A method for producing Pb-212 and Ac-225 isotopes is disclosed. The method comprises irradiating a Ra-226 containing target with charged particles and/or photons for producing at least Ac-225 isotopes and Ac-224 isotopes. The method further comprises after a cooling time, applying chromatography for separating actinium from the remaining fraction containing radium. The method also comprises, after a first further waiting time, applying extraction chromatography using a resin having an 18-crown-6 ether or an equivalent of an 18-crown-6 ether, as extractant in HNO3 and/or HCl for separating Pb from the remaining fraction containing radium.

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.

The present disclosures relates to an ion beam assembly where a relatively small deflection angle (approximately 15° from the center of the beam line) is used in conjunction with two beam dumps located on either side of the beam. In some embodiments, the combination of the two beam dumps and the magnet assembly can provide an ion beam filter. In some embodiments, the resulting system provides a smaller, safer and more reliable ion beam. In some embodiments, the ion beam can be a proton beam.
