“…Chronologically the next method developed was a monitor based on coherent synchrotron radiation (CSR) [5][6][7]. From a continuous operation and monitoring point of view, non-invasive beam diagnostics are preferred, and those based on measuring synchrotron light are preferred to those based on transition radiation for this reason.…”

“…Such a monitor, based on sensitive Schottky diode detection, was able to detect signals at down to 1 microA beam current easily [8]. Some care must be taken when applying techniques based on spectrum detection of bunch shapes, because it is actually highly unlikely that the bunch shapes in linacs, recirculating or not, are Guassian, or that calculations of the bunch shape based on Guassian distributions will lead to meaningful results [5,9]. So even at the earliest stages of the CEBAF work on coherent detection techniques, it was understood that some other method would be needed to obtain the bunch shape accurately.…”

In this paper, the electron beam diagnostics developed for recirculating electron accelerators will be reviewed. The main novelties in dealing with such accelerators are: to have sufficient information and control possibilities for the longitudinal phase space, to have means to accurately set the recirculation path length, and to have a means to distinguish the beam passes on measurements of position in the linac proper. The solutions to these problems obtained at Jefferson Laboratory and elsewhere will be discussed. In addition, more standard instrumentation (profiling and emittance measurements) will be reviewed in the context of recirculating linacs. Finally, and looking forward, electron beam diagnostics for applications to high current energy recovered linacs will be discussed.

“…Another technique for determining bunch length by measuring coherent radiation is to use bending magnet radiation [21]. The advantages of using an undulator rather than a bending magnet are that it may be placed in a straight section of a linac and that it creates little or no dispersion or emittance growth.…”
