There was less energy recovery using Pulsotron-4 than using Pulsotron-3, so several tests were performed to fix that using configuration-2, so we improved in one test from 14.5% to 70%. That solution will be added to several others to help to generate more energy than used.
In the graph can be seen the old coil in blue and the new one that is grey. The other two plotlines correspond to other sensors:
Test S4015
We added some captures made during the tests:
S4018 captured using a high resolution cameraS4018 high speed capture
Fortunately, only a launcher was broken during tests that were replaced immediately
It was made new tests using Configuration-2 but a low magnetic field was measured.
It was processed videos and data generated in the last test campaign revealing an intriguing capture that seems to be a soul in pain. Unfortunately, the flames revealed that plastics used in sealing burns due to tests, so it must be replaced by more harder isolation material
During the last test campaigns performed from 25 October 2020 until 7 of November, 9 tests were performed, and as a result, 1.6-2.57 megateslas was reached, or perhaps higher, but unfortunately our star oscilloscope of 4 gigahertz is out for calibration, but in the last test only 287 kiloteslas was obtained.
Test S4008
Then the magnetic sensor was removed so then an inspection revealed new damaged parts, then Pulsotron has dismantled again for inspection to see some plasma leakages discovered using the new high-speed cameras. and as a result, several parts must be changed.
As a result of the autopsy of the magnetic sensor, the high strength nylon custom case was broken so plasma entered into and severy burned the flex PCB board. In the following photo in the upper right corner can be observed the crack and the path used by the plasma to enter trough the PCB board
Mag-5.4 sensor burned
After the dismantling of the reactor, we must wait for spare parts to repair it. Also, a new configuration could be tested, but after repeat the last test using a new sensor that is now being building
After the first three tests, several parts of the fusion reactor were broken, so the parts are replaced and a general refurbishment was made, including new ERC, new magnetic sensor-5, and large shield to stop alpha particles and X rays to allow to make tests using thermonuclear fuel.
The new Pulsotron-4C2 is active and full operative now. Here is an image of its first test with new parts:
