Measurement and Simulation of Space Charge Effects in a Multi-beam Eletron Bunch from an Rf Photoinjector
نویسندگان
چکیده
We report on a new experimental study of the space charge effect in a space-charge-dominated multi-beam electron bunch. A 5 MeV electron bunch, consisting of a variable number of beamlets separated transversely, was generated in a photoinjector and propagated in a drift space. The collective interaction of these beamlets was studied for different experimental conditions. The experiment allowed the exploration of space charge effects and its comparison with three-dimensional particle-in-cell simulations. Our observations also suggest the possible use of a multibeam configuration to tailor the transverse distribution of an electron beam.

Longitudinal Bunch Lengthening Compensation in a High Charge Rf Photoinjector
In high charge RF photoinjectors for wakefield two beam acceleration studies, due to the strong longitudinal space charge, bunch lengthening between the photocathode and photoinjector exit is a critical issue. We present beam dynamics studies of bunch lengthening in an RF photoinjector for a high charge electron beam and describe methods to compensate the bunch lengthening to various degrees. I...
متن کاملSimple limits on achieving a quasi-linear magnetic compression for an FEL driver
Free electron lasers (FEL) need a very bright electron beam in three dimensions and a high peak charge density. In order to compress an initially longer electron bunch generated from the photoinjector, magnetic bunch compression systems are widely employed. In this paper, first harmonic RF linearization and its associated requirements are reviewed. Meanwhile it is also briefly discussed what is...
متن کاملA 90 Ghz Photoinjector
Photocathode rf guns depend on mode locked laser systems to produce an electron beam at a given phase of the rf. In general, the laser pulse is less than σz = 10° of rf phase in length and the required stability is on the order of ∆φ = 1°. At 90 GHz (W-band), these requirements correspond to σz = 333 fsec and ∆φ = 33 fsec. Laser system with pulse lengths in the fsec regime are commercially avai...
متن کاملCherenkov Ring to Observe Longitudinal Phase Space of a Low Energy Electron Beam Extracted from Rf Gun *
Particle distribution of the electron beam extracted from a thermionic RF gun in longitudinal phase space is crucial for electron bunch compression. Because space charge effects in the RF gun are not fully understood, an efficient bunch compression scheme employing magnetic chicane or alpha (α-) magnet is not easily designed. In order to measure the distribution in the longitudinal phase space ...
متن کاملExperimental investigation of the longitudinal beam dynamics in a photoinjector using a two-macroparticle bunch
We have developed a two-macroparticle bunch to explore the longitudinal beam dynamics through various components of the Fermilab/NICADD photoinjector. Such a two-macroparticle bunch is generated by splitting the ultraviolet pulse from the photocathode drive laser. The presented method allows the exploration of radiofrequency-induced compression in the 1.625 cell rf-gun and the booster cavity. I...
