WebBunch Compressor Chicane Specification 1 Basic Lay Out The compression scenario of the XFEL incorporates three bunch compressor magnet chicanes. They consist basically of four dipole magnets (for a sketch see Fig. 1) with focusing elements for optics adjustment grouped around them. The center straight section WebOct 21, 2014 · The facility will mainly consist of an injector that provides a high-current quasi-CW electron beam at 250 keV and two s uper c onducting (SC) accelerating modules in order to accelerate beam to 15–40 MeV energy, interspaced by a magnetic bunch compressor. The accelerator will drive two independent optical resonator systems …

WebAug 21, 2002 · The first stage bunch compressor in the NLC injector complex compresses the e+/e- beams from a bunch length of 5 mm rms to 0.5 mm rms at the beam energy of 2 GeV. To obtain this compression ratio, the compressor rf section operates with an rf frequency of 1.4 GHz and a voltage of about 140 MV while a magnetic wiggler is used to … WebI settled on a used Keeley Caverns and a Keeley Compressor, two pedals I’ve been wanting for a while. We head to the register and he starts ringing me out (grabbed some strings and such too). But then he stops and groans and starts to apologize saying he can’t sell them because they are on a 30 day hold the cops make them do (his words) to ... dish network prescott az

Why we need bunch compressorsBeams in damping rings has bunch length of 6 … WebThe purpose of the NLC bunch compressor is to re duce the bunch length, which is about 4 mm at extraction from the damping rings, to 100 /xm, suitable for injection into the main X-band linac. The bunch compressor may have to compensate bunch-to-bunch phase errors due to beam-loading in the damping ring unless the latter is com dish network port 1 no signal
