A pre-moderator collar covers moderator dead space near the exit window to redirect neutrons and raise thermal yield without losing cold output.
A non-rotating screw and rotating threaded drive let multi-leaf collimators move faster with stable, accurate leaf positioning.
A high-conductivity dielectric layer forms a heat bridge in atom traps, limiting RF heating to protect vacuum quality and reduce surface noise.
Using zero-nuclear-spin metastable states and optical frequency combs, this case suppresses magnetic-field Zeeman shifts in atom interferometers.
