2. Oxygen-free copper - Wikipedia

   en.wikipedia.org/wiki/Oxygen-free_copper

   The CuOFP capsule used as overpack for spent nuclear fuel disposal in the KBS-3 concept (Swedish version). Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.

3. Thousandth of an inch - Wikipedia

   en.wikipedia.org/wiki/Thousandth_of_an_inch

   A thousandth of an inch is a derived unit of length in a system of units using inches.Equal to 1 ⁄ 1000 of an inch, a thousandth is commonly called a thou / ˈ θ aʊ / (used for both singular and plural) or, particularly in North America, a mil (plural mils).

4. Gauge factor - Wikipedia

   en.wikipedia.org/wiki/Gauge_factor

   Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as: [ 1 ] G F = Δ R / R Δ L / L = Δ R / R ε = 1 + 2 ν + Δ ρ / ρ ε {\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac ...

5. Angular diameter - Wikipedia

   en.wikipedia.org/wiki/Angular_diameter

   Angular diameter: the angle subtended by an object. The angular diameter, angular size, apparent diameter, or apparent size is an angular separation (in units of angle) describing how large a sphere or circle appears from a given point of view.

6. Helium - Wikipedia

   en.wikipedia.org/wiki/Helium

   Helium remains liquid down to absolute zero at atmospheric pressure, but it freezes at high pressure. Solid helium requires a temperature of 1–1.5 K (about −272 °C or −457 °F) at about 25 bar (2.5 MPa) of pressure. [107] It is often hard to distinguish solid from liquid helium since the refractive index of the two phases are nearly the same

7. Coronagraph - Wikipedia

   en.wikipedia.org/wiki/Coronagraph

   Coronagraph image of the Sun. A coronagraph is a telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise would be hidden in the object's bright glare – can be resolved.
