# Building 1 Extension (B1E)—Enabling Sustained Scientific Advancement and Innovation

### Expected Impacts

Construction of the B1E will dramatically enhance NIST's measurement capability and will directly support the needs of industry and academia. Some of the anticipated impacts include the ability to:

• make precision frequency measurements above 100 GHz (100 billion cycles per second), which are required for advanced commercial electronics, military systems, and homeland security;

• measure and perform research on the properties of materials at the single-atom level needed for the development of quantum and nanotechnologies;

• measure forces below 10-12 newtons (one billionth the weight of a feather) to understand the inner workings of cells and to apply this measurement capability to other physical systems; and

• make timing measurements with uncertainties reduced to one part in 10-18 (the equivalent of one second in 30 billion years), enabling whole new generations of position, navigation, and guidance systems.
