Quick Shot

Cryogenic targets are assembled in a Class-100 cleanroom using a target assembly station consisting of a microscope, motion stages with micrometer positional control, and cameras. The assembler is shown attaching an 865-µm-diameter capsule to a 17-µm-diameter silicon-carbide fiber, as viewed in the computer monitor on the left. All the assembly and characterization processes are performed in the cleanroom environment to maintain the cleanliness of the target’s surface. The target is then processed in the Cryogenic Target Handling System.
