Notes:
Rutherford scattering of pulsed 1 MeV proton beams is developed as a time-resolved fluence diagnostic for proton transport experiments. The incident beam is scattered from a thin aluminum target and recorded with a silicon PIN detector. For a pinched-beam diode, fluences of protons transported in 1 Torr air are consistent with fluences determined with calorimeters, provided the proton energy is smaller than expected from the measured ion current and voltage. Beam bunching is observed as the flight path increases, consistent with reduced proton energy at the head of the beam.
