| Abstract |
Streak cameras are commonly used for bunch length measurement. In normal beam modes, bunch lengths are on the order of 10 ps. For the study of microbunch instabilities, a low alpha single bunch mode is implemented with bunch lengths approaching 1 ps and beam current in the tens of microamps. In order to reliably measure such a short bunch at low beam currents, the input optics for the streak camera must be optimised for sufficient incident light intensity and high resolution in both sweep directions. This is achieved through the use of reflective input optics in which a pinhole is imaged to provide a small circular Point Spread Function. Furthermore to precisely measure the bunch length, the calibration of the dual sweep must be known. Here we describe a calibration method using electrical delays to incorporate calibration information within streak camera images.
