abstract:

    line_1:        This test defines the procedure used to evaluate HRS detector focus for both
    line_2:        detectors.  The detector mask edges are used to examine the focus for 5
    line_3:        values of the tweak current.  This test is included in HRS Standard High
    line_4:        Voltage Turn On, and does not need to be scheduled separately in the OV
    line_5:        timeline.  It will be used if problems are detected during the high voltage
    line_6:        turn on test, or the detectors are found to be out of focus.  The results of
    line_7:        this test will be used to update the HRS high voltage and tweak values.

  question:        2
    section:       1
    line_1:        This test will provide the results needed to optimize the values of the HRS
    line_2:        high voltage and tweak current.

!

  question:        3
    section:       1
    line_1:        A series of high resolution X scans are performed using 1 deflection step
    line_2:        between each sample with the flat field lamp on using detector 1.  The scans
    line_3:        will step across the detector mask edge at center Y deflections.  Each scan
    line_4:        will be done with one of five tweak values chosen to bracket the default
    line_5:        tweak value.  The procedure is then repeated for side 2.

!

  question:        5
    section:       1
    line_1:        During OV this test does not need to be scheduled, but should be available in
    line_2:        case the results of the high voltage turn on indicate the detector is out of
    line_3:        focus.  It may also be used if routine science data indicates refocusing of the
    line_4:        detector(s) is necessary.
    line_6:        Prerequisites:
    line_8:        1.  HRS High Voltage Turn On must have been completed and high voltage must be
    line_9:        on.

!

  question:        7
    section:       1
    line_1:        1. The sharpness of mask edge will be analyzed to determine the ideal high
    line_2:        voltage and tweak setting.

!

  question:        8
    section:       1
    line_1:        This is an internal test and does not require any special pointing of the
    line_2:        telescope.  This test does not require the HRS to be the prime instrument.
    line_4:        There is no target list with this proposal.

!

  question:        10
    section:       1
    line_1:        1.  Test design support.
    line_3:        2.  Test execution support team.
    line_5:        3.  Data analysis facilities.
    line_7:        4.  Data analysis personnel.
