Ultrahigh vacuum-compatible sockets for pin grid arrays used in nanoscale and atomic physics

摘要

Pin grid arrays are often used for packaging devices for nanoscale and atomic physics experiments performed in ultrahigh vacuum (UHV). These arrays require their complementary socket arrays for measurements, yet UHV-compatible sockets are not commercially available. In this paper, the authors describe the design and construction of fully UHV-compatible sockets, which provide reliable electronic contact down to cryogenic temperatures and survive repeated insertion-retraction cycles.
