The biggest challenge to this facility is that of maintaining a clean environment. An air circulating system moves filtered air from the ceiling to the floor. Small particles are removed, so that less than 10,000 particles per cubic foot of air remain. The biggest source of contamination to the room occurs when humans enter. Because of this the engineers and technicians who work in this room wear special garments.
Booties cover the shoes, a jump suit covers the clothes, arms, and legs.
A face mask and rubber gloves are worn, as well as a hat to cover the hair. These garments are specially designed and laundered. Carbon fibers in the garments prevent the humans from damaging the instrument with static electricity. The material is lint-free. Access to this room is limited.
