An experimental investigation of airflow-induced vibrations within the multiplicity and vertex detector
This report summarizes an experimental investigation of vibrations within the multiplicity and vertex detector (MVD). In particular, the maximum displacements of several MVD components were determined from accelerometer measurements of vibrations induced by an electronics air-cooling system. For an MVD inlet air volumetric flow rate of 0.022 m{sup 3}/s, maximum displacements of several MVD components including a multi-chip module, the Rohacell inlet air plenum, and an aluminum structural cross support, were found to be on the order of 1.5 {mu}m. Consequently, it was concluded that air induced vibrations will not significantly interfere with the MVD`s long-term structural integrity or operating performance. 2 refs., 3 figs., 1 tab.
