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:
At this test campaign, it was tested the new magnetic sensor MAG5 that is designed to measure magnetic fields up to 4 gigahertz and withstand ten times larger magnetic fields than the old MAG4 sensor.
As a result in the test 4002 the magnetic field was so large that saturated oscilloscope channels corresponding for the two more close sensors, giving 3.92 Megateslas at the third
At test 4003 it was measured 2.67Megateslas, but the magnetic sensor was broken. Also, several isolation parts of the Pulsotron was broken and must be replaced.
As a conclusion, the performance of Pulsotron-4 generates 5.3 times larger magnetic fields than Pulsotron-3
In order to measure the Time of Flight (TOF) and plasma ball expansion, it was installed three oscilloscope probes connected to three dipole sensors installed sequentially, that measure the electric resistivity of the passing plasma through the dipoles.
After a delay of 11 days, we could mount it in 3 days and make to work the Pulsotron-4 fusion experiment (it is not a Fusion Reactor as long as not reactions are done yet). We performed it first discharge at 100% power.
In the last tests, it was measured the charging current in the capacitor knowing the capacitance and the voltage change measured at capacitor terminals. The current is extracted from plasma affected by the ejected particles produced during fusion
The recovered energy beats new record. 1.2MA flowing towards the energy recovery capacitors was measured. The pulse is short, 23 microseconds only, then the capacitor is discharged at 200 kiloamps
Also, we have to inform that Pulsotron-4 entering in service is delayed as several components must be replaced, so tests are performed using the damaged Pulsotron-3 reactor. It is expected that the reactor can definitely break down at any moment
At test S3070 we used the ERC-08 Electric Recovery Coils and 88.13% of the net energy injected in the target was recovered. But the main scientist suffered an electric shock from the recovery capacitors, then to increase the energy recovered, new security systems must be installed.
At the test S3071 the coils were separated from target to reduce damage from reaction but the energy recovered decreased to half, that is still much higher than the last test campaign
We are happy because recovery 200% allows us to begin to sell commercial reactors.
In next tests, the recovered energy was 26.89% (test S3072), 22.5% (T3073) and 17.74% (T3074), but in last two tests the magnetic field was maintained during a long time at 7.36 and 4.91 Megateslas. It is due to fusion reactions generates an intense magnetic field. It is clear that the magnetic field is an important parameter not only before but also during and after fusion is performed.
In the last test the generated energy and magnetic field could go down due the ERC structure was blown away, so it will be difficult to repeat tests, especially the setup of the S3070 in the Pulsotron-3 reactor.
As can be seen in the graph below the electric generation sufered a step increase from <5% to over 20% after the introduction of the new ERCs that will be used in the next Fusion Reactor
A new world record in energy recovery from a Fusion reactor at test S3068, was established in 22.6% without nuclear fuel, and it is expected to recover 10.6 times more loading targets with thermonuclear fuel, and there are still several technologies to improve that numbers, so there is a lot of room to obtain more energy recovery than injected. This is a good notice for a damaged Pulsotron-3 that works at 88.9% of nominal voltage.
Fortunately there are good news because we are waiting parts of the new Pulsotron-4 that is 6 times more powerful and have another improvements over Pulsotron-3. It is estimated that the Pulsotron-4 new fusion machine must enter in operation before 10th September
It was made tests 3059 to 3063. In test 3059 it was tested new coils coiled around glass pipes, as expected they broke, as it happened before, but unfortunately, the obtained energy was very low, and also it was broke the support structure MAG-8, then the glass pipe coils are withdrawn. The laboratory got covered with glass pieces that had to be cleaned, but the MAG-8 was replaced by a copy and tests continued to increase the recovered energy a 50% more using the same coils than test 3054, but failed to obtain more energy. It was investigated at post-processing the data and it was discovered a short cut in the high-speed video, so the discharged energy in the negative line of the capacitor decreased the stored energy to levels similar to recovered one in the record test 3054
The following tests had the same problem, it was detected that the short-circuited coils were overheated due to the intense current loss of the recovered energy, so we will solve in the next test campaign to obtain better energy return as long as we need to double the recovered energy to have electric energy ignition that would make Pulsotron reactors profitable
In test S3055 it was installed the repaired MAG-4 sensor and the new energy recovery coil REC-8. As a result, the energy recovered was 419% higher than in test S3049, but lower than in the last test, so some modifications from coils REC-4 to REC-8 must be reverted.
It was totally destroyed the MAG-4 sensor and could not be repaired again, so in the following tests magnetic field was not measured.
in test S3056 the coil was mounted around a pyrex glass. As a result, it was recovered 42% less energy. The recovery REC-6 was totally destroyed, also the pyrex glass coil was totally destroyed but in the high-speed video it was seen it emitted luminescence after the electromagnetic pulse was finished
It was tested using different storage of energy than using capacitors and new energy recovery coils in tests 3057 and 3058 but it generates high voltage but low current energy pulses so energy recovery is too difficult
