Both the x-ray astrophysics and microanalysis communities have a need for large format arrays of high-spectral-resolution x-ray detectors. To meet this need, we are transferring our successful single pixel Transition Edge Sensor (TES) x-ray microcalorimeter design into a multi-pixel array. We will use SQUID multiplexing technology initially developed for our IR bolometer arrays to reduce the wiring to the cold stage of our cryostat. Room temperature digital feedback electronics have been developed to simplify to read-out of large numbers of pixels, and microfabrication techniques are being explored to enable the fabrication of large, close-packed arrays of TES microcalorimeters.
