Assess number of cold cycles pre-amp seen for nominal mission; compare to previous flight
heritage and validate whether this needs to be heater controlled to minimize stresses over the
mission.                                                                                        6/13/2011                 Delory

Perform EM (or latest prototype) tests with a beam of energy equal to the lowest required
energy, sufficient to validate the optics including the demonstrated elimination of any stray
potentials in the optics that adversely affect the conversion factor (GF*Eff) of the instrument
at such energies. That is, verify that the response function at the lowest required energy
meets the requirement that applies at higher energies.                                             7/5/2011               McFadden

Switch to A121 preamps, or carefully limit sensitivity to accommodate the highest expected
fluxes without saturation, or implement an attenuator like those on SWIA and STATIC.               7/5/2011               Mitchell

Review modeling assumptions that went into the EUV glint assessment (solar reflections off         7/5/2011
of Ge coated MLI on HGAS ), especially the way complex shapes (e.g. antennas, MLI) are
modeled: true (smooth) or approximate (facetted). ..                                                                      Westfall

Suggest doing a continuity check of the HV arming plug on final insert at the launch site.                                Curtis
Suggest repeating the life test of the EUV mechanism in the same sequence as for the
anomalous run                                                                                                             Westfall
Consider changing the foil fabrication step where the frame manually
“chases” (chart 8-74) the floating film onto the frame. ..                                                                McFadden
