Analysis method:

iv)

Untriggered, deadtime-free simultaneous data taking of all events of class i) and ii) is foreseen. Class iii) events are collected as required for monitoring using selective hardware triggers.

v)

The collection of 10 pile-up free -e decay events for both and is planned. This allows complementary analyses of clean events with a single as well as of more complicated, but higher statistics data with several simultaneous in the TPC.

The developed method can be easily adapted to a muon-on-request beam, which would allow about a ten fold boost in the statistics, without increasing the systematic uncertainties.
