abstract:

    line_1:        After warm-up to the nominal high voltage, the trim current
    line_2:        is set to zero, and the high voltage to a lower value.
    line_3:        Spectra are then obtained with the 0.1-PAIR aperture, G190H,
    line_4:        the Pt-Ne lamp, and three different X-BASEs; these will allow
    line_5:        the determination of the focus and x-pitch. Measurements
    line_6:        with the TALEDs will be obtained through the 0.1-PAIR
    line_7:        aperture to determine the y-pitch. The voltage is
    line_8:        then increased in steps of 400V, with a range of 2KV, and
    line_9:        spectra obtained at each step. If this test fails to give a
    line_10:       good focus, a contingency test is also given.
    line_12:       This program will result in an instruction flow change to
    line_13:       the detector high voltage setting, the x-pitch value, the
    line_14:       y-pitch value, and possibly the trim current value.
    line_16:       Changed 9/5/89 to match Implementation Plan. A "dummy"
    line_17:       target was added on 10/6 to allow it to go through TRANS-
    line_18:       FORMATION.
    line_19:       Changed 12/6/89 to reflect implementation request.

  question:        3
    section:       1
    line_1:        After high voltage warm-up, set the trim current to zero,
    line_2:        and the detector HV to 22.1 (blue) or 21.1 (red). Obtain a
    line_3:        series of three spectra with the following configuration:
    line_5:        .......0.1-PAIR lower aperture
    line_6:        .......grating G190H
    line_7:        .......8 x-steps 1 y-step
    line_8:        .......Pt-Ne lamp/ direct
    line_10:       at three different X-BASEs. Then obtain a map of the
    line_11:       photocathode with the following configuration:
    line_13:       .......0.1-PAIR lower aperture
    line_14:       .......camera mirror
    line_15:       .......1 x-step 85 y-step
    line_16:       .......TALED
    line_18:       Increase the HV by 400V, wait
    line_19:       1 minute, and repeat the observations as above. Continue to
    line_20:       increase the HV for 5 steps until the maximum voltage is
    line_21:       24.1 (blue) or 23.1 (red).

  question:        5
    section:       1
    line_1:        If this test fails to yield a good focus, a contingency test
    line_2:        is also included. The test is similar to that above, except
    line_3:        that the high voltage is set to a low value, and the focus
    line_4:        trim current is varied.
    line_6:        This observation should be scheduled 4 days after the
    line_7:        coarse y-base mapping (proposal 2187). Wait 4 days before
    line_8:        scheduling the fine y-base mapping (proposal 2188).
    line_9:        The correct value for the initial y-base, determined in the
    line_10:       prerequisite program, will need to have been updated
    line_11:       prior to the start of this test.
    line_13:       The value for the Y parameter is based on ground data. It
    line_14:       will need to be updated based on the data in proposal 2187.
    line_15:       If an offset Y parameter is available, replace Y=469 and
    line_16:       Y=-309 with Y-OFF=+253.
    line_18:       If a good focus is not found, we will want to schedule the
    line_19:       COND lines as rapidly as possible, as no further FOS
    line_20:       observations can be obtained until this program has been
    line_21:       successfully completed.
    line_22:       These observations MUST occur during non-SAA impacted orbits.

!

  question:        6
    section:       0
    line_1:        This test is not stray light sensitive. All observations are
    line_2:        internal Pt-Ne and TALED lamp measurements.

!

  question:        7
    section:       0
    line_1:        Data reduction will be performed at the ST ScI, and the
    line_2:        analysis will be performed using FOS IDT computer facilities.
    line_3:        This is a verification of ground-based analysis, so no data
    line_4:        will need to be added to the PODPS pipeline. However, this
    line_5:        program will determine the correct detector high voltage,
    line_6:        trim current, x-pitch, and y-pitch values to be used
    line_7:        in obtaining data, and this information will need to be
    line_8:        updated after any change is measured.

!

  question:        10
    section:       0
    line_1:        Data analysis, research assistant support, and funding will
    line_2:        be provided under NASA's FOS development contract.
