In order to test new energy recovery coils to be used in the next Pulsotron-5 fusion reactor, it was refurbished about 40% of the Pulsotron-4, then it was installed the chamber ERC-45, then it was made a test. The test objective and results are confidential, but two captures of the test are released.
About the ERC-47 it was damaged the plasma deflector, the foundation, the first stage, and the launcher, but we hope to repair to make two new tests
During March 2021 three test campaigns were performed making tests 4048 to 4051 using the fusion chamber ERC-39.
In the last test number 4051, it was read an average radiation measurement of 21.2 millivolts instead of 0.262 to 0.293mV measured in previous tests. The measurement is done using a broadband high-speed photodiode at a 50 ohms load. In order to avoid saturating the photodiode, a black body filter is inserted that reduces the energy received to 1/15000
Here is the plot result without loss reduction. It was used a 4GHz 12bit oscilloscope. Channel 1 corresponds to the photodiode sensor:
And here is the plot corresponding to the famous S4051 test. Channel 2 and 3 are connected to two magnetic sensors capable to measure up to 100 kiloteslas:
The useful effect was advised the first time after processing the high-speed video sequences. As can be seen in the test S4050 a lot of energy is wasted. That does not happens in the $052 test:
The measured results of two tests T3073 and T3074 performed in 28 August, 2020 are presented in this paper. Tests are conducted in the z-pinch type nuclear fusion reactor Pulsotron-3 with the target loaded with Hydrogen-Boron (H+B11) thermonuclear fuel. A group of Energy Recovery Coils (ERCs) were mounted to recover the electric energy directly from the plasma for the first time in the world and ERCs stored the energy in several large capacitors. During the test T3073 and T3074 the energy recovery capacitors recovered 22.59% and 17.74% of the injected energy at the target. A magnetic sensor MAG-4 consisting of inductor coils and dipoles were installed in Pulsotron-3 to measure the Time Of Flight (TOF) of the plasma and the magnetic field generated due to nuclear fusion. Magnetic fields more than 4 megateslas are obtained during the two tests. It is also observed that Pulsotron-3 with the target loaded with thermonuclear fuel generated 20-34 times larger peak magnetic fields and 12-18 times larger stabilized magnetic fields compare to the tests done using unloaded target (dummy loads). In this proposed technology Pulsotron-3 utilizes thermonuclear fuel to generate clean electric power without CO2 footprint and reduce the operational cost.
Low resolution and high-speed capture made during the test
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.
The test was done in order to check magnetic mirrors using the ERC-27B chamber that survived but a small plastic part was unglued due the ERC body that is made using 4.5mm aluminum thick inflates like a balloon during some milliseconds during the plasma ball expansion
The new chamber ERC-27 was tested using nuclear fuel and also magnetic mirrors. In test 4037 performed last week the chamber was damaged but could be repaired. Then it was repaired and made a second test, then the ERC-27 survived but not the launcher that is used to close the switch that was blown. The generated energy was 25% lower but it could be measured the magnetic field that blown the last record that is now over 10.5 Megateslas, but it can not be measured accurately because that it was 282% higher than the maximum level of the sensor and also higher than the scope scale. During 3.8 microseconds it was established the field over 2.5 Megateslas at the nuclear fuel surface, and also 35 kiloteslas at a larger distance.
