The CESR Test Accelerator (CesrTA) program targets the study of beam physics issues relevant to linear collider damping rings and other low emittance storage rings. This endeavor requires new instrumentation to study the beam dynamics along trains of ultra-low emittance bunches. A key element of the program has been the design, commissioning and operation of an x-ray beam size monitor capable, on a turn by turn basis, of collecting single pass measurements of each individual bunch in a train over many thousands of turns. The x-ray beam size monitor development has matured to include the design of a new instrument which has been permanently integrated into the storage ring. A new beam line has been designed and constructed which allows for the extraction of x-rays from the positron beam using a newly developed electro magnet pair. This new instrument utilizes custom, high bandwidth amplifiers and digitization hardware and firmware to collect signals from a linear InGaAs diode array. This paper reports on the development of this new instrument and its integration into storage ring operation including vacuum component design, electromagnet design, electronics and capabilities.
