Laser Temporal Pulse Shaping Experiment for Sparc Photoinjector
Laser for driving high brightness photoinjector have to produce UV square pulse which is predicted to be the optimum profile for emittance compensation in advanced photoinjectors. The longitudinal laser pulse distribution, according to numerical simulations for the SPARC photoinjector, must be square with rise and fall time shorter than 1 ps and flat top variable up to 10 ps FWHM. In this paper...
متن کاملX-band Photoinjector Beam Dynamics*
SLAC is studying the feasibility of using an X-band RF photocathode gun to produce low emittance bunches for applications such as a mono-energetic MeV γ ray source (in collaboration with LLNL) and a photoinjector for a compact FEL. Beam dynamics studies are being done for a configuration consisting of a 5.5-cell X-band gun followed by several 53-cell high-gradient X-band accelerator structures....
متن کاملA Study of Higher-band Dipole Wakefields in X-band Accelerating Structures for the G/nlc
The X-band linacs for the G/NLC (Global/Next Linear Collider) have evolved from the DDS (Damped Detuned Structure) series. The present accelerating structures are 60 cm in length and incorporate damping and detuning of the dipole modes which comprise the wakefield. In order to adequately damp the wakefield, frequencies of adjacent structures are interleaved. Limited analysis has been done previ...
متن کاملA Permanent-magnet Focused X-band Photoinjector
A Plane-Wave-Transformer (PWT), integrated photoinjector operating at an X-band frequency (8.547GHz) is being developed by DULY Research Inc. in a DOE SBIR project, in collaboration with UCLA and UCD/ILSA. Upward frequency scaling from an S-band PWT photoinjector would result in a compact photoinjector with unprecedented brightness. Challenging technological innovations are required at X-band. ...
متن کاملHigh Magnetic Fields in Couplers of X-band Accelerating Structures
Recent high power tests of x-band accelerating structures at SLAC have shown that their performance is limited by breakdowns in couplers. The behavior of these breakdowns is consistent with a model of pulsed heating due to high magnetic fields. The observed damage is located in the region of high magnetic fields. To calculate these magnetic fields, 3D electrodynamics models of the couplers were...
