Abstract

Production assembly for an isotope production system. The production assembly includes a mounting platform including a receiving stage that faces an exterior of the mounting platform. The mounting platform includes a beam passage that opens to the receiving stage and a stage port that is positioned along the receiving stage. A particle beam is configured to project through the beam passage and through the receiving stage during operation of the isotope production system. The stage port is configured to provide or receive a fluid through the receiving stage during operation of the isotope production system. The production assembly also includes a target assembly having a production chamber configured to hold a target material for isotope production. The target assembly includes a mating side that is configured to removably engage the receiving stage during a mounting operation.

First claim

What is claimed is:

1. A production assembly for an isotope production system, the production assembly comprising:
a mounting platform including a receiving stage that faces an exterior of the mounting platform, the mounting platform including a beam passage that opens to the receiving stage and a stage port that is positioned along the receiving stage and separate from the beam passage, wherein a particle beam is configured to project through the beam passage and through the receiving stage during operation of the isotope production system, and wherein the stage port is configured to provide or receive a fluid through the receiving stage during operation of the isotope production system; and
a target assembly having a production chamber configured to hold a target material for isotope production, the target assembly including a mating side that is configured to removably engage the receiving stage during a mounting operation, the mating side including a target port and a beam cavity that is aligned with the production chamber, the target port being in flow communication with a body channel that extends through the target assembly, wherein the target port fluidically couples to the stage port and the beam passage aligns with the beam cavity as the target assembly is mounted to the receiving stage.

2. The production assembly of claim 1 , wherein the mounting platform includes a platform base and a stage adapter that is secured to the platform base and includes the receiving stage, the stage adapter including an insulative adapter body that is positioned between the platform base and the target assembly and electrically separates the platform base and the target assembly during operation, the stage adapter including the stage port and a portion of the beam passage.

3. The production assembly of claim 2 , wherein the mounting platform includes a sealing member positioned within the beam passage and the target assembly includes a target neck that is configured to project into the beam passage when the target assembly is mounted to the mounting platform, the sealing member surrounding the target neck within the beam passage.

4. The production assembly of claim 1 , further comprising a locking device having a movable actuator that is coupled to one of the mounting platform or the target assembly, the movable actuator configured to be engaged by the other of the mounting platform or the target assembly during the mounting operation thereby causing the movable actuator to move to a locked position, the locking device holding the target assembly against the mounting platform when the movable actuator is in the locked position.

5. The production assembly of claim 1 , wherein the mounting platform includes an electrical contact positioned along the receiving stage and the target assembly includes an electrical contact positioned along the mating side, the electrical contact of the target assembly being electrically coupled to a surface that defines the production chamber, the electrical contacts of the mounting platform and the target assembly engaging each other during the mounting operation.

6. The production assembly of claim 1 , wherein the stage port is an outlet stage port and the mounting platform further comprises an inlet stage port, and wherein the target port is an inlet target port and the target assembly further comprises an outlet target port, the outlet stage port and the inlet target port configured to be fluidically coupled to each other when the target assembly is mounted to the receiving stage and the inlet stage port and the outlet target port configured to be fluidically coupled to each other when the target assembly is mounted to the receiving stage, wherein the outlet stage port is configured to be in flow communication with the inlet stage port through the target assembly when the target assembly is mounted to the receiving stage.

7. The production assembly of claim 6 , wherein the target assembly includes a cooling channel that flows proximate to the production chamber to absorb thermal energy therefrom, the outlet stage port being in flow communication with the inlet stage port through the cooling channel.

8. The production assembly of claim 6 , wherein the outlet stage port is in flow communication with the inlet stage port through the production chamber.

9. The production assembly of claim 1 , wherein the mounting platform includes a plurality of the receiving stages, each of the receiving stages capable of removably engaging, at separate times, the target assembly.
