Particle detectors

[TimeSpaceLightForce]

A detector with largest flat surface is to be installed
inside a lab cubicle that has 1 sq.m opening and 1m
deep underground to maximize capture of particles.

Is the shape of detector a square or a circle?

Is the opening a square that is 1 meter on a side?
Can the opening take the shape of the detector?

My guess is a both the opening and the detector should be circles, but it's not clear that both shapes are variable.

the buried cube is 1x1x1m metal box without cover on top

Where will the detector be placed? Sorry i think i haven't understood clearly.

please install inside the (cube) box without exposure above the ground

you made the detector a square along the diagonal of the cube?

That is 1 x 1 m only because the side is 1 m, there is a larger square that will fit in the cube.

The detector would be sqrt(2) x sqrt(2)

Oops ignore that...

which is larger..the biggest square that fits in a cube or the biggest circle that fits in a cube?

I strongly dislike AutoCAD so many rough memories

A square with area 9/8.

It's easy to see the square of a side is (3/4)² + (3/4)².

one surface area to go...

I didn't say, but it seems obvious that

if you make the detector a circle, you throw away area needlessly.

The constraint for a circle to fit does not preclude adding corners to it.

So a circular shape is always suboptimal.

that is, if the circle is inside the square..

assures the detector is inside a cube.

[Yodell]

or rather Post 5 does that .. no exposure above ground actually means that no part of the circle or square can be : "out-of-the-box" so to speak...

ok, why is a circular detector bigger than the square detector ?

Circles aren't bigger or smaller than squares until constraints are added.

1. If the constraint is a given perimeter, circles are bigger (area wise)
2. If the constraint is maximum and minimum values of x and y, then squares are bigger.

The present constraints are of the second type.

[TimeSpaceLightForce]

...inside a cube the largest square that can fit in is not coplanar with the largest circle that can fit in.

inscribed in bobby go's regular hex cut lies the biggest circle within the cube..
