In order to check the setup for the next Pulsotron-4 fusion reactor, it was arranged the Pulsotron-4 switch launcher and electrodes at Pulsotron-3. Also, it was installed the new Energy Recovery coil REC-4 and the new MAG-4 magnetic sensor with a wideband of 4.5 Gigahertz, but a 200MHz scope was used while the new 4GHz scope arrives. As a result, the energy recovery was increased a 497% over previous S3049 test.
It was destroyed the launcher finger and the magnetic sensor in three parts. The magnetic sensor could be repaired but not the launcher finger so tests stopped
