abstract:

    line_1:        This test takes dark count data from
    line_2:        two HSP detectors, IDT #3 (vis) and the
    line_3:        PMT and with high voltage on and off and
    line_4:        with RIU polling on and off.  The purpose
    line_5:        of this test is to verify the RIU noise
    line_6:        is eliminaged if RIU polling is off.
    line_7:        Note:  This is RPSS file # TBD.  Revision
    line_8:        history:  Richards 1/4/89
    line_9:        This is based on 1379, HSP-i1

  question:        2
    section:       1
    line_1:        The justification for the proposed test is to
    line_2:        determine the effect of the RIU noise on the
    line_3:        detector dark count for two HSP detectors,
    line_4:        IDT #3 and the PMT.  The IDT #3 dark count
    line_5:        is observed at one of the locations observed
    line_6:        in HSP-i1.  The dark count data are obtained
    line_7:        with high voltage on and off and with RIU
    line_8:        polling on and off.  This test is considered a
    line_9:        "delta SV" test to be run if RIU noise is
    line_10:       observed in HSP-i1.  This test also serves as
    line_11:       a test case for the development of ground system
    line_12:       software.
    line_13:       The in-flight results will be compared with the
    line_14:       data from HSP-i1 and data from ground testing.

  question:        3
    section:       1
    line_1:        This test is to be performed during dark time,
    line_2:        and during the PMT portion of the test the ST
    line_3:        should be pointing at the dark earth.
    line_4:        1) IDT3: the HSP is to be configured in the
    line_5:        single-color, one aperture mode (HSP/x, SINGLE)
    line_6:        with the detector at nominal high voltage and
    line_7:        PAD settings. The detector is to be sampled at
    line_8:        the central cathode position.  This position has
    line_9:        the following detector coordinates:
    line_10:       (H,V) = (2000,1900)
    line_11:       An integration of 5 minutes in length,
    line_12:       sampling at 0.1 second samples, is to be
    line_13:       obtained with detector high voltage on. Then
    line_14:       a second sampling is done with high voltage off.
    line_15:       The third and fourth 5 minute integrations are
    line_16:       performed with RIU polling turned off.
    line_17:       2) PMT: Operating at the nominal high voltage
    line_18:       the dark current is to be sampled for 5 minutes
    line_19:       with high voltage on and 5 minutes with high
    line_20:       voltage off.  The RIU polling is then turned
    line_21:       and the observations repeated.  Data are to be
    line_22:       taken in the ALL format.  There are a total of
    line_23:       eight 5 minute observations in this test.

  question:        5
    section:       1
    line_1:        OV This is a repeat of an OV activity. It is
    line_2:        assumed that initial detector turn-on and all
    line_3:        other early OV tests have been completed.
    line_5:                                       This is an
    line_6:        internal test and no external targets are
    line_7:        observed. Dark time is required for the entire
    line_8:        test, and for the PMT portion of the test it
    line_9:        is required that the ST be pointing at the dark
    line_10:       earth. To perform the test, it is assumed that
    line_11:       each detector has been successfully powered up
    line_12:       for 30 minutes, which is the case if the
    line_13:       standard stabilization times are used.

  question:        6
    section:       1
    line_1:        Dark time and non-SAA passage are
    line_2:        required for this test.

!

  question:        7
    section:       1
    line_1:        The data reduction is planned as follows:
    line_2:        For both of the detectors the mean
    line_3:        dark count rate (digital mode) will be
    line_4:        determined and compared to the data obtained
    line_5:        from HSP-i1.  The data taken with RIU polling
    line_6:        on will be compared to the data taken with
    line_7:        RIU polling off to confirm that RIU noise can
    line_8:        be completely eliminated by turning off RIU
    line_9:        polling.

!

  question:        10
    section:       1
    line_1:        Data reduction and analysis will be supported at
    line_2:        the Space Astronomy Lab at the University of
    line_3:        Wisconsin in Madison.
