Spectrometer Specifications
• Wakefield accelerated electrons ejected collinear with proton beam: need to separate the 2 and measure energy of electron beam only.
• Must be able to resolve energy spread as well as energy: spectrometer must accept a range of energies, probably 0-5 GeV.
• Current conceptual layout:– Dipole mounted ~2 m downstream of plasma exit
induces dispersion in electron beam.– Scintillator screen 1 m downstream of dipole
intercepts electron beam ONLY.– Dispersion gives energy-dependent position spread
on screen.– Scintillator imaged by intensified CCD camera
viewing upstream face of scintillator screen.
