The Jefferson Lab X-ray program continues its evolution from a “curiosity experiment” at the FEL to a full fledged user program. I will discuss three relatively major developments:

Calculations showing a high brightness x-ray source using the main CEBAF accelerator,

Pump(IR)-probe(X-rays) possibilities with the FEL Upgrade machine and initial experiment design, and

a new concept for a “two color” Thomson X-ray generator.
