Abstract [en]

The Polarized Gamma-ray Observer Lite (PoGOLite)  is a balloon experiment which will  measure polarization of soft gamma rays in the energy range of 25 - 80 keV. Together with PoGOLite will also an auroral diagnostics package called Alfvén Labo- ratory Balloon ExpeRimenT (ALBERT) fly to measure auroral emissions as well as the surrounding background. The main part of ALBERT is two spectrophotometers that consist of a photo multiplying tube, lenses and a Fabry-Perot etalon. The Fabry-Perot etalons are mounted in a lens mount  that  is angle adjustable with  a stepper motor based linear actuator.  To support the instruments and to keep the etalons at a stable temperature  there are an multitude  of sensors and controllers at work.  The sensor data is collected organized and stored in a onboard memory as well as sent down to ground for real time analysis. This thesis covers the design and construction of the electronics as well as the VHDL  code for the main controller.  It is also supposed to work as a manual over how to run the experiment.
