ARC detector array electronics (on floor, at left), and motor controller rack (at right)
Clearing space in electronics rack to install ARC array electronics
Installation of the test versions of the detector ribbon cabling. The test cables use copper wires instead of the Manganin wires used in the cryo set.
Detector warm cabling and detector connector headers on the warm bulkhead.
Detector array ribbon cables from warm bulkhead to connectors mounted in the cold bulkhead. Also seen are the ribbon cables that plug into the cold side of the same cold bulkhead connectors. The reason for the connectors is to ensure a light- and heat-tight cold volume starting at the cold bulkhead.
