International Linear Collider at Fermilab

Sources
The Fermilab NICADD Photoinjector Laboratory (FNPL) is an 16 MeV electron linac. It produces a high-intensity, low emittance beam. The principal components of the facility are a pulsed UV laser, a normal conducting RF gun with a cæsium telluride photo-cathode, a 9-cell superconducting cavity, a magnetic chicane, and a beam transport line. The accelerator is used for studies in accelerator science, plasma wake-field acceleration and focusing, and channelling radiation.

The accelerator's design is nominally identical to that of the TeSLA Test Facility 1 (TTF1) at DESY. The RF gun for TTF's second-generation injector was in fact designed, fabricated, and commissioned at the FNPL facility. The 9-cell superconducting cavity being used at FNPL was provided by DESY.

The construction of the photo-injector was undertaken as a collaboration between Fermilab and:

The Department of Physics and Astronomy at The University of California at Los Angeles.
The Department of Physics and Astronomy at The University of Rochester.
The Laboratorio Acceleratori e Superconduttività Applicata of INFN Milano (Italy).
The TeSLA Test Facility at DESY-Hamburg (Germany).
