During February it was built and tested two new configurations: The spectacular coil tower ERC34 and the ERC39. It must be advised that every configuration usually is very different from the other. It was made tests S4044, S4045, S4046, and S4047 in four test campaigns.
Both combustion chambers successfully survived without any damage to the tests.
Also, new magnetic sensors were built using inox steel cases
As can be seen, the spectacular blast happens just after plasma compression. The energy is recovered using coils.
