LDEF (Prelaunch), AO054 : Space Plasma High-Voltage Drainage Experiment, Tray D10 The prelaunch photograph of The Space Plasma High Voltage Drainage Experiment (SP HVD) was taken in SAEF II at KSC prior to installation on the LDEF. The SP HVD experiment consist of two identical sets of experiment hardware mounted in three (3) inch deep LDEF experiment trays, one tray is located in the LDEF position B04 adjacent to the LDEF trailing edge and the other is located at LDEF position D10 adjacent to the LDEF leading edge. Each set of SP HVD experiment hardware, self-contained within the experiment tray, consist of six (6) fiberglass reinforced epoxy modules carrying charged dielectric samples on top and the power supplies and electronics below. Four (4) dielectric samples, Kapton with Vapor Deposited Aluminum on one side (VDA-Kapton), are bonded to each of the fiberglass modules with a silver filled conductive epoxy adhesive. The spaces between the dielectric sample covered modules and between the modules and the tray flanges are covered by strips of VDA-Kapton attached with acrylic transfer adhesive and Kapton tape. Each experiment tray also contain two solar cell modules. Power for the experiment is provided by LiSO2 batteries supplied by the LDEF Project. The experiment was assembled using non-magnetic stainless steel fasteners. Reflections of the surrounding area can be seen in the VDA-Kapton dielectric samples.
