Abstract
A shield for absorbing radiation emitted by a target during operation of a cyclotron. The shield includes an inner box structure having a recess for receiving the target. In addition, the shield includes a first plurality of shield elements arranged in a layered configuration about the inner box structure. The shield also includes an outer box structure for receiving the inner box structure and the first plurality of shield elements. Further, a second plurality of shield elements is arranged in a layered configuration about the outer box structure. The shield elements are arranged in both horizontal and vertical orientations and are removable.
Claims21
A shield for absorbing radiation emitted by a target during operation of a cyclotron, wherein the target is located within a target enclosure, comprising:
- an inner box structure having a recess for receiving the target enclosure;
- a first plurality of shield elements arranged in a layered configuration about the inner box structure to form a first shielding arrangement having first shielding characteristics;
- an outer box structure for receiving the inner box structure and the first plurality of shield elements;
- and
- a second plurality of shield elements arranged in a layered configuration about the outer box structure to form a second shielding arrangement having second shielding characteristics.
A shield for absorbing radiation emitted by a target during operation of a cyclotron, wherein the target is located within a target enclosure, comprising:
- an inner box structure having a recess for receiving the target enclosure;
- a first plurality of shield elements arranged in first and second orientations about the inner box structure to form a first shielding arrangement having first shielding characteristics;
- an outer box structure for receiving the inner box structure and the first plurality of shield elements;
- and
- a second plurality of shield elements arranged in the first and second orientations about the outer box structure to form a second shielding arrangement having second shielding characteristics.
A shield arrangement for absorbing radiation emitted by a target during operation of a cyclotron, wherein the target is located within a target enclosure, comprising:
- an inner box structure having a recess for receiving the target enclosure;
- a first plurality of removable shield elements arranged about the inner box structure to form a first shielding arrangement having first shielding characteristics;
- an outer box structure for receiving the inner box structure and the first plurality of shield elements;
- a second plurality of removable shield elements arranged about the outer box structure to form a second shielding arrangement having second shielding characteristics wherein the inner and outer box structures and first and second plurality of shield elements form a layered shield assembly;
- and
- a movable shield for receiving the layered shield assembly.
A shield arrangement for absorbing radiation emitted by a target during operation of a cyclotron, wherein the target is located within a target enclosure, comprising:
- an inner box structure having a first size and a recess for receiving the target enclosure;
- a first plurality of first shield elements arranged about the inner box structure wherein the first shield elements are reconfigurable to provide additional or less shielding or to accommodate an alternate size inner box structure wherein the first shield elements form a first shielding arrangement having first shielding characteristics;
- an outer box structure having a second size for receiving the inner box structure and the first plurality of shield elements;
- a second plurality of second shield elements arranged about the outer box structure wherein the second shield elements are reconfigurable to provide additional or less shielding or to accommodate an alternate size outer box structure wherein the second shield elements form a second shielding arrangement having second shielding characteristics and wherein the inner and outer box structures and first and second plurality of shield elements form a layered shield assembly;
- and
- a movable shield for receiving the layered shield assembly.
