We have studied the use of the SLAC linac to drive FELs at wavelengths down to a few Angstroms. Lasing would be achieved in a single pass of a low emittance, high peak current, high energy electron beam through a long undulator by Self-Amplified-Spontaneous-Emission (SASE). About 10{sup 13} photons per pulse can be produced in 100 fs pulses at a 120 Hz rate, corresponding to brightness levels of about 10{sup 22} average and 10{sup 32} peak. Peak power level are tens of GW. Electron energies of 10-20 GeV are required. Significant improvement of FEL performance seems possible using harmonic generation techniques according to results from numerical simulations.
