The 5.6 MΩ series resistor is split up to reduce the voltage on each of them. The diode partially removes the noise spikes from the high voltage circuit.

This is the raw pulse at point A, about 2 V for 100 µs, then falling back to 0 V in the next several 100 µs. Remainings of the little noise spikes are still visible: This is the raw pulse at point A, about 2 V for 100 µs, then falling back to 0 V in the next several 100 µs.
