Commissioning experience and beam physics measurements at the SwissFEL Injector Test Facility

Commissioning and Measurements of the Neptune Photo-injector

The photo-injector for the Neptune Advanced Accelerator Laboratory is introduced. Its component parts, including the radio frequency gun, photo-cathode drive laser system, booster linac, RF system, chicane compressor, beam diagnostics, and control system are described. The injector is designed to produce high brightness, short pulse electron beams. Measurements of the photo-injector beams inclu...

Neutron measurements from beam-target reactions at the ELISE neutral beam test facility.

Measurements of 2.5 MeV neutron emission from beam-target reactions performed at the ELISE neutral beam test facility are presented in this paper. The measurements are used to study the penetration of a deuterium beam in a copper dump, based on the observation of the time evolution of the neutron counting rate from beam-target reactions with a liquid scintillation detector. A calculation based ...

Beam Power Limitations during the TTF2 Injector Commissioning

Commissioning of the Slc Injector*

For every cycle of the SLC, the injector is required to launch two electron bunches and a single positron bunch into their rsspective emittance damping rings. Each bunch is to have a population of 7.5 x 10” particles/bunch, an energy of 1.21 GeV, and a full width energy spread of less than 2%. The electron beams are produced from a thermionic cathode, bunched, and accelerated to about 200 MeV. ...

Beam Based Alignment at the Kek Accelerator Test Facility

The KEK Accelerator Test Facility (ATF) damping ring is a prototype low emittance source for the NLC/JLC linear collider. To achieve the goal normalized vertical emittance γεy = 20 nm-rad, magnet placement accuracy better than 30 μm must be achieved. Accurate beam-based alignment (BBA) is required. The ATF arc optics uses a FOBO cell with two horizontally focusing quadrupoles, two sextupoles an...
