Diagnostics for Ultrashort Bunches

PDF Version Also Available for Download.

Description

Recently, producing and maintaining short bunches in accelerators has become a forefront issue. Examples of accelerators that require short bunches are high quality nuclear physics accelerators, free electron laser driver accelerators, next generation linear colliders, and linac-based fourth generation light sources. Large bodies of work have accumulated at various sites on producing, measuring, and maintaining ultrashort bunches. In this paper such work is reviewed, with particular emphasis placed on diagnostic techniques that may be applied in the subpicosecond rms bunch duration domain. Instrumentation based on both time domain and frequency domain methods are discussed: in the frequency domain, coherent radiation ... continued below

Description

Recently, producing and maintaining short bunches in accelerators has become a forefront issue. Examples of accelerators that require short bunches are high quality nuclear physics accelerators, free electron laser driver accelerators, next generation linear colliders, and linac-based fourth generation light sources. Large bodies of work have accumulated at various sites on producing, measuring, and maintaining ultrashort bunches. In this paper such work is reviewed, with particular emphasis placed on diagnostic techniques that may be applied in the subpicosecond rms bunch duration domain. Instrumentation based on both time domain and frequency domain methods are discussed: in the frequency domain, coherent radiation detection techniques in the far infrared receive special emphasis. In addition to the usual problem of measuring the bunch longitudinal distribution function, it is also important to have efficient ways to control the bunch length in short bunch machines. Solving this problem involves instruments with somewhat different properties than the standard ones. Consequently, some space is devoted to several devices, both in use and proposed, that are useful in the problem of controlling ultrashort bunches.
