Popis:	We describe the technique and the results of a measurement of the width of a fine structure pulse from our L‐band electron linear accelerator. The pulse width was measured by measuring the width of the Cerenkov light pulse generated by the electron beam using a streak camera–TV camera–computer system. With very low beam currents, a pulse width of 20 psec (FWHM) was measured, while at higher beam currents a pulse width of 27 psec was measured showing a space‐charge effect. In addition, a broad energy spectrum for the electrons or improper focusing into a 270° bending magnet was also shown to increase the pulse width of the beam after it had traversed the magnet.
