An on-axis, angled, rotator device is disclosed. The rotator device may include a container containing a slot for receiving a sample. An angle of the slot may be configured to be between 0 and 180 degrees relative to a perpendicular irradiation plane of a radiation device. The rotator device may include a cup positioned within an opening of the container. Additionally, the rotator device may include a driveshaft configured to transmit torque to cause the cup to be rotated when the cup is positioned within the opening. When the sample resides within the slot and the driveshaft transmits the torque to the cup, the cup may cause the sample to rotate about a center axis of the sample. The angle of the slot containing the sample and the rotation of the sample about the center axis may facilitate uniform radiation exposure to the sample when the radiation device emits radiation.

An apparatus and method for providing uniform X-Ray irradiation to material carried in a plurality of containers. The apparatus includes an X-Ray tube providing a linear source of irradiation and also a 4 pi (360 degrees) irradiation. The material to be irradiated is placed in containers suspended on a vertical carousel wheel type structure. The individual containers are mounted receive irradiation throughout the rotation of the wheel. The tube is mounted approximately at the axis or center of the wheel. In operation, the containers of material are rotated around the tube, and due to their orientation and the 4 pi irradiation from the source, each and all the containers receive a uniform irradiation for the material contained therein.
A linear source of x-rays is disclosed wherein an elongated filament, mounted within a cylindrically formed anode, provides electrons around the filament, and along the length of said filament. The anode that comprises a high Z material such as gold, receives the electrons and emits X-rays in a 360 degree arc and along a substantial length of the anode. In one embodiment the tube is used for irradiation purposes.
