At least one secondary fiber intersects the primary fiber at a non-zero angle and is in optical contact with the primary fiber.

Each base fiber has. a width less than the width of the primary fiber.

Fiber obtained from wood by either of the above methods is called primary, or virgin, fiber.

The primary fiber has a width less than about 5 microns.

Monofilament” (1) or filament is the smallest increment of fibre, usually several micrometres in diameter.

Monofilament” or filament is the smallest increment of fibre, usually several micrometres in diameter.​

At least one primary fiber, which is a scintillating optical fiber, is positioned to receive radiation from a gamma ray source.

Each base fiber of the plurality of base fibers has a first end attached to the primary fiber and a second end attached to the substrate.

A fabricated microstructure includes a substrate, a primary fiber, and a plurality of base fibers.

At least one primary fiber, which is a scintillating optical fiber (21) is positioned to receive radiation from a gamma ray source.

6 The primary fiber is pressed into a highly compressed bale, similar to other fibers like cotton, wool, and polyester.
