Paper Abstract

The James Webb Space Telescope (JWST) will have several on-board instruments, of which the Mid-Infrared Instrument (MIRI) will cover imaging and low resolution spectroscopy in the 5-28 micron region. To achieve the many science goals for MIRI, the detector arrays must be capable of achieving high sensitivity. The primary obstacle to high sensitivity is the total noise. The total noise is often dominated by two main parts: the read noise of the multiplexer and the shot noise of the detector array's dark current. We present recent results of the measured read noise for several candidate multiplexers from the first Si-foundry run.
