Here we describe the manufactured KIAE-2p planar
undulator designed for the Inverse Free Electron Laser
experiment at the University of California in Los Angeles.
New technology enabled to fabricate the installation
responding to the stringent requirements on mechanical
construction accuracy and magnetic field strong tapering.
Results of the magnetic field measurements by different
methods are given. The obtained magnetic field maps
were used for final simulations of the acceleration
process. It is shown that for nominal electron beam and
laser beam parameters up to 30% of electrons can be
captured and accelerated from initial 14 MeV up to 52
MeV. Special analysis of the undulator acceptances for
these parameters is made. It is shown that the acceleration
is possible up to energies >30 MeV for rather wide ranges
of laser pulse energy, Rayleigh length and e.b. emittance.
