Abstract :
Present and future generations of particle accelerating and storage machines are expected to develop ever-decreasing electron/positron bunch lengths, down to 100 μ and beyond. In this paper a method for measuring the longitudinal profiles of ultrashort (1000 μ≈10 μ) bunches, based on: 1) the extreme field compaction attained by ultrarelativistic particles, and 2) the reduction of the group velocity of a visible light pulse in a suitably-chosen dielectric medium, is outlined
