Spark initialization voltage dependence on initial Ion concentration
We found out that there is obvious dependence of Spark initialization voltage on initial Ion concentration. The detailed feasibility study of the ionization concentration in the range of altitudes requested is ongoing, results to be provided in the range of interest. Concerning the BEXUS7 floating altitude of 27km, the ambient pressure was 19Pa, Resp. BEXUS6 at floating 30km with 10Pa.
Therefore 10Pa is the relevant minimum for our experiment, with start of relevant function of our ionization tube function above 10km of altitude, with ambient pressure of 20kPa. Dependence plots of temperature and pressure coming soon.

Tests
A thermal camera for thermal design at CTU is available. EMC test of the ionization tube has to be prepared.
