First Results

&lt;p&gt;Two experimental sounding rockets were launched from And&amp;#248;ya Space Center&lt;br&gt;(Norway) devoted to investigate the phenomenon of polar mesospheric winter&lt;br&gt;echoes (PMWE). PMWE are relatively strong radar returns during winter,&lt;br&gt;observed at various frequencies (e.g. &amp;#8776; 50 MHz Maarsy or &amp;#8776; 224 MHz with&lt;br&gt;EISCAT). Despite possible tracing capabilities for dynamics in the Meso-&lt;br&gt;sphere over a wide annual and altitudinal extend, the formation process is&lt;br&gt;still not understood. To clarify the formation mechanism and proof theories,&lt;br&gt;an experimental setup consisting of two rocket payloads were designed. Aim-&lt;br&gt;ing for measuring neutral air temperature, relative and absolute densities of&lt;br&gt;plasma constituents (electrons, ions, charged aerosols), neutral air and trace&lt;br&gt;gases as well as turbulence. In-situ measurements were complemented by&lt;br&gt;ground based measurements of multiple radars and lidars.&lt;br&gt;We show results from contemporaneous multi instrumental in-situ measure-&lt;br&gt;ments and ground based observations based on the first part of the PMWE-&lt;br&gt;Project and discuss them in the context of most relevant theories.&lt;/p&gt;

The fabrication of the aluminum bridge test vehicle for use in the crystallographic studies of electromigration involves several photolithographic processes, some common, while others quite unique. It is most important to start with a clean wafer of known orientation. The wafers used are 7 mil thick boron doped silicon. The diameter of the wafer is 1.5 inches with a resistivity of 10-20 ohm-cm. The crystallographic orientation is (111).Initial attempts were made to both drill and laser holes in the silicon wafers then back fill with photoresist or mounting wax. A diamond tipped dentist burr was used to successfully drill holes in the wafer. This proved unacceptable in that the perimeter of the hole was cracked and chipped. Additionally, the minimum size hole realizable was > 300 μm. The drilled holes could not be arrayed on the wafer to any extent because the wafer would not stand up to the stress of multiple drilling.
