A light assembly is provided that includes a holder and multiple light pipes. The system provides the flat-field response, representing the spatial variations in the sensitivity of the recorded output, with a signal-to-noise ratio greater than can be achieved in a single submicrosecond streak record. 5% to 65% acrylic acid residues, from 10% to 80% C2-C4 alkyl acrylate residues, from 2% to 25% lipophilically modified acrylate residues and residues of a crosslinker that has no ester or amide functionality. Control circuitry controls operation of the integrated circuit in dependence on the monitored conditions associated with the power gate switch.
