The Shadow Pen.

If you imagine that this world is created with a light pen, then you can rewrite some elements of this world with a shadow pen, and so, what is it?

Like the usual pen for writing, this feather pen has two planes that do not create light as a light pen, but create a shadow that fills on both sides, right and left, with light. The total rate of loss of the shadow of the track, or the filling of the shadow, this pen is equal to two speeds of light, since the loss of the shadow occurs from two sides with the speed of light.

Something like this: Anura Rafael Write Time Tourbillon Watch That Becomes A Pen

An approximate working scheme of the process, instead of neutrinos, multidirectional calibrated laser beams can act:

And what can you do with such a pen? Why is it needed?
For example, write a new base element. Concretely, the metal is hydrogen. For example, if two planes of the pen are formed by a plane of the neutrino flux, the extremities of the oval of the resulting meson of metallic hydrogen will be cut off by the neutrino flux planes, from both sides. It may be necessary to concentrate more energy, for this we can accelerate the convergence of the outer radius to the bunch of producing constants.

And so we need, a sweeper: X-ray Pump Probe (XPP) Instrument

Flow Meter and Flow Transmitter: Soft X-ray Materials Science (SXR) Instrument

Work Camera: Matter in Extreme Conditions (MEC) Instrument

Workspace: Serial Femtosecond Crystallography (SFX) at LCLS

Further, we need a team of specialists who have the necessary methods for calculating all stages of the process. And the main observer.
