1.1 Overview
The nanowire system has three main physical components, as identified in Figure 2:
1. The “Electronics Unit” that provides system thermometry and nanowire device control and
monitoring.
2. The “Opus One Unit” consisting of the vacuum and cryogenic components, nanowire de-
tectors, and nanowire optical and electrical connections.
