Two of the end mirrors are in the east hut.
Research Technician Ben Brubaker works on the beam splitter vacuum system.
The Fermilab Holometer is a new kind of instrument designed to study the quantum character of space itself. It measures the quantum coherence of location with unprecedented precision.
Laser light passing through an arrangement of mirrors will show whether space stands still, or whether it always jitters by a tiny amount, carrying all matter with it, due to quantum-geometrical fluctuations. We call this new property of space time ``holographic'' noise.
The experiment will help us understand space and time better: what they are made of, and how they relate to matter and energy.
The experiment, also known as Fermilab E-990, is currently collecting data.
