WE PROPOSE TO THE H-TIDS ITDS 2019 CALL TO FURTHER ENHANCE CAPABILITIES FOR SOFT X-RAY AND EUV DYNAMIC IMAGING. WE WILL DEVELOP HIGH SPEED READOUT BACK-ILLUMINATED CMOS SOFT X-RAY (SXR) DETECTORS TO 1) MITIGATE SATURATION AND BLOOMING OF SOLAR FLARE IMAGES 2) STUDY HIGH TIME CADENCE (0.05 SECOND VARIATIONS) PHENOMENA AND 3) GENERATE SPECTRAL IMAGES OF ACTIVE REGIONS (ARS) CORONAL BRIGHT POINTS (CBPS) SMALL FLARES (A - B GOES CLASS) AND ASPECTS OF THE QUIET SUN (QS). THE HIGH SPEED READ OUT DETECTORS ALONE CAN PROVIDE COURSE LOW TIME CADENCE (MINUTES) MODERATE SPECTRAL RESOLUTION (RESOLVING POWERS E/DE OF 10 40) SPECTRA. TO ENABLE NARROWBAND (RESOLVING POWERS E/DE OF 50 100) SPECTRAL IMAGES WE WILL ALSO DESIGN DEPOSIT AND MEASURE REFLECTIVITY OF SXR NARROWBAND MULTILAYER MIRRORS (MLM) AS A PROOF OF CONCEPT. THIS WORK WILL SETUP A FUTURE PROPOSAL FOR SPACEFLIGHT DEMONSTRATIONS ON FUTURE SOUNDING ROCKET LAUNCHES CUBESATS AND LARGE SATELLITE MISSIONS. OUR PROPOSED WORK DIRECTLY ADDRESSES THE NASA HELIOPHYSICS DIVISION AND NRC DECADAL SURVEY FUNDAMENTAL SCIENCE QUESTION WHAT CAUSES THE SUN TO VARY? AND ADDRESSES THE NASA HELIOPHYSICS SCIENCE GOAL OF EXPLORE THE PHYSICAL PROCESSES IN THE SPACE ENVIRONMENT FROM THE SUN TO THE EARTH AND THROUGHOUT THE SOLAR SYSTEM. QUESTION 1 IS DO SOLAR FLARES VARY ON SUB-SECOND TIMESCALES AND IF SO WHAT DOES THIS TELL US ABOUT THE MAGNETIC FIELD? SXR FILTERS CAN BE USED TO MODIFY THE SPECTRAL BANDPASS AND INTENSITY RANGE OF HIGH SPEED READOUT (40 HZ - 1 000 HZ SPEED VARIES AS A FUNCTION OF READOUT REGION SIZE) CMOS DETECTORS WHICH CAN BE USED TO STUDY THE BRIGHTNESS EVOLUTION OF SOLAR FLARES ON SUB-SECOND TIMESCALES. FURTHERMORE CHARGE BLOOMING WHICH COMMONLY OCCURS WITH CCDS AND HAS HINDERED HINODE X-RAY TELESCOPE LARGE FLARE IMAGES CAN BE MINIMIZED WITH CMOS DETECTORS. EACH CMOS PIXEL IS UNIQUELY ADDRESSABLE WITH SEPARATE PREAMPLIFIER AND READOUT CAPABILITIES AND ARCHITECTURE TO PREVENT CHARGE FROM SPILLING TO ADJACENT PIXELS. THIS CAN GREATLY INCREASE SXR FLARE IMAGE QUALITY. INTENSITY VARIATIONS OF ARS CBPS AND THE QS CAN ALSO BE DETERMINED ON SUB-SECOND TIMESCALES DEPENDING ON THE INSTRUMENTATION THAT IS COUPLED TO THE DETECTOR.
