High brightness electron sources for linac based free-electron lasers (FELs) are being developed at the Photo Injector Test facility DESY, Zeuthen site (PITZ). Production of bunches with extremely small transverse emittance is focus PITZ scientific program. The photoinjector optimization in 2008--2009 a bunch charge 1, 0.5, 0.25, and 0.1 nC resulted measured values which beyond requirements European XFEL [S. Rimjaem et al., Nucl. Instrum. Methods Phys. Res., Sect. A 671, 62 (2012)]. Several...
The beam dynamics in transverse deflecting structures, operating streaking mode, is discussed concentrating on slightly nonrelativistic particle energies. Transverse offsets of the average trajectory, bunch lengthening, and defocusing as well emittance growth due to nonlinearities cavity field are considered. analysis reveals origin leads proposals for their suppression. An optimized design which combines minimal aberrations with a high rf efficiency proposed.
This report describes the conceptual design of a proposed free electron laser test facility called CLARA that will be major upgrade to existing VELA accelerator at Daresbury Laboratory in UK. able number new schemes have been but require proof principle experiment confirm they perform as predicted. The primary focus on ultra short photon pulse generation which take lasers into whole regime, enabling area science emerge.
The Transverse Deflecting System XFEL TDS INJ has been built as the part of European X-ray Free Electron Laser for longitudinal bunch profile and slice emittance measurements. 0.7 long Structure (TDS), system, on base disk-loaded structure with hybrid EH-wave, operating frequency 2997.2 MHz pulse input RF power up to 3 MW. built, tuned installed in Injector beam line. All design parameters have got at low level. passed through whole including TDS.

A separated function, variable energy, drift tube linac (DTL) operating in CW mode is being built for the ISAC radioactive beam facility at TRIUMF. Longitudinal focusing achieved by positioning 105 MHz rebunching cavities immediately upstream of second, third and fourth IH accelerating tanks. The three devices must operate a relatively low /spl beta/ (2.3%, 2.7%, 3.3%) deliver peak effective voltages 0.19, 0.26 0.32 MV respectively. In addition geometry allow large voltage dynamic range...
Extraordinary emittance requirements in the nm range (normalized) and pulse lengths down to a level of ∼10 fs for REGAE bunches demand both operation at low bunch charges on sub-pC scale very careful beam handling. The S-band RF deflecting cavity is intended diagnostics longitudinal parameters. For first time structure, specially developed optimized rotation has been realized deflector. provides minimized aberrations distribution field combined with an improved efficiency. main steps design,...
China is characterized by a special attitude to having meal. Traditions and customs related food are basic family social patterns for the inhabitants of country. Such pattern communicative function meal together as basis maintaining existing establishing new relationships. That tradition, which was formed on territory many millennia ago, influenced socio-cultural, natural, historical, economic factors. In turn, it itself created corresponding mental phenomena in bearers Chinese culture,...
In proton therapy, depth scanning of the irradiated object is performed by changing Output Energy (OE) accelerated beam. pulsed linear accelerators, adjustment OE usually amplitude and/or phase fi eld in accelerating elements from one RF pulse to another. The application non-inertial traveling wave sections makes it possible change quickly during pulse. constant gradient section determined both input signal and process propagation dispersive structure. calculation results structure when...
