Measurements of the Beam Longitudinal Properties in the Fermilab Linac

R. Sharankova, J-P. Carneiro, E. Chen +1

The Fermilab Linac delivers 400MeV, 25mA H; beam. The longitudinal bunch parameters are reconstructed using a Bunch Shape Monitor (BSM) installed in the middle of the Linac. Fo…

Low Emittance Growth in a LEBT with Un-Neutralized Section

L. Prost, J. -P. Carneiro, A. Shemyakin

In a Low Energy Beam Transport line (LEBT), the emittance growth due to the beam's space charge is typically suppressed by way of neutralization from either electrons or ions, whic…

First Observation of Self-Amplified Spontaneous Emission in a Free-Electron Laser at 109 nm Wavelength

J. Andruszkow

We present the first observation of Self-Amplified Spontaneous Emission (SASE) in a free-electron laser (FEL) in the Vacuum Ultraviolet regime at 109 nm wavelength (11 eV). The obs…
