An Improved Ion Drift Meter.

Abstract : This report provides the necessary operating, diagnostic and repair information for using and maintaining the Improved Ion Drift Meter (IDM). The report is divided into four sections. Section 1 contains the instrument description and theory of operation. Section 2 contains a description of planned spacecraft-level instrument testing, stimulation requirements and procedures, and instrument handling and safety. Section 3 contains a copy of the End-Item Acceptance Test (EIAT) that describes test results and presents calibration data and procedures. Any recalibration of the instrument will be performed per the EIAT calibration test procedure. Section 4 contains a list of the schematics, drawings, parts lists and wiring lists that describe the as-built configuration of the instrument. This documentation is available to AFGL upon request.
