The Fermilab NICADD Photoinjector Laboratory (FNPL) is an 18 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 channelling radiation.
The accelerators design is nominally identical to that of the TeSLA Test Facility (TTF) at DESY. The RF gun for TTFs 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
