LPP Public Processed Data Base 2009-2013

Processed Data from 2009-2013 now available for researchers

LPPFusion, Inc. is here making available the data in our Processed Data Base to all researchers, both professional and amateur. This data provides the key observations for each shot from the start of operation of Focus Fusion-1 in 2009 through the end of 2013 for four instruments: the Main Rogowski coil (MRC), High Voltage Probe (HVP), the Near Time of Flight (NTF) and Far Time of Flight (FTF) detectors. This gives data on the current and voltage produced during a shot and the neutrons and x-rays emitted. We are making this data publically available in the expectation that other researchers will be able to use the data to provide new insights into the functioning of the Dense Plasma Focus device and advance the field generally.
In contrast to the data base of raw data made public last year, this data has been processed by our own JavaFusion program into more useful form. The program, developed by LPP Electrical Engineer Fred van Roessel, measures such key parameters as the peak current and peak voltage of each shot, and identifies and measures the timing, width and height of each neutron and x-ray peak. It automatically aligns the data in the NTF and FTF, showing which peaks correspond in the two instruments. This is work that almost any researcher would need to do before further analyzing the data, so we are here eliminating a lot of effort and duplication of work.
The data is presented in three sets of Excel files that can be downloaded from this page. These contain the processed data for the MRC, the HVP and the combined data from the NTF and FTF. Each set contain separate files for each of the five years of data. An additional “Data Summary” file shows the conditions for each shot, such as the amount of gas filling the chamber, the voltage used to charge the capacitors, and the number of capacitors fired, among others.
Other files on this page help to interpret the data. The Data Description provides the meaning of the column headers on each file. The Technical Instrument Description provides technical details on the instruments and their calibration. The Delay Summary files give the measured delays from the time the instruments collect the data to the time recorded by the oscilloscopes, allowing researchers to line up data from different instruments to the nearest ns (billionth of a second). Finally, the Alignment Description files describe the exact field-of-views of the NTF and FTF.
A detailed description of the JavaFusion program will be posted to this page shortly. Raw data is still available to qualified researchers on request to us at LPP@LPPfusion.com. We ask that all those downloading this data share their analyses with LPP, publish their results and of course cite our work accordingly.
