Spatial Map Cross Scans

Thermal Cycle Three-Row Scan

PCR thermal-cycle heat is clearer when cycle count changes across several exact rows. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Two cycles make six programmed steps

Heat per step is 100 joules. With 3 steps per cycle and 2 cycles, one well uses 600 joules and the chip uses 4800 joules.

Four cycles double the per-well heat

The same step heat and wells now use 4 cycles, so one well uses 1200 joules and the chip uses 9600 joules.

Six cycles make the scaling line visible

6 cycles give one-well heat 1800 joules and chip heat 14400 joules. Three rows show cycles as a multiplier.
