The control

846 flat tiles around a cylinder. This is what a conventional detector looks like.

• Tile columns141
• GapsTrue gaps by design
• Material ⟨X/X₀⟩3.977×10⁻³

Reference. Every gain on this page is measured against it.

How it folds

A herringbone of parallelograms, mapped onto a cylinder.

• Gain at the ends94.4%
• Thinly covered bins0.04%
• Extra material+1.88%

Best for designs limited by multiple scattering. A small gain that costs almost nothing.

How it folds

A twisted, triangulated cylinder that shortens and rotates when compressed.

• Gain at the ends97.5%
• Thinly covered bins1.45%
• Gain vs facet count+2.31 pp at 6 → ~0 at 32

Best for the most coverage, if tracking can handle material near the fold vertices.

How it folds

A diamond pattern, familiar from how thin cylindrical shells buckle.

• Gain at the ends98.9%
• Thinly covered bins1.86%
• Fold 15° → 75°84.5% → 94.2%, material triples

Set aside. Most material, most thin spots, and fewer particles caught than Kresling.
