Tungsten Cathode Completed, En Route to FF-1

cut_cathode

The critical tungsten monolithic cathode, key to LPPFusion’s next set of experiments, has finally been completed and shipped. It arrived at Tungsten Heavy Powder headquarters in San Diego, California on Monday, Feb.23 from their manufacturing facilities in China. It is expected to arrive at LPPFusion’s Middlesex, NJ laboratory around March 2. “For a long time,…

LPPF Releases Processed Data to Researchers and the Public

fred

LPPFusion, Inc. has made available on our website the data in our Processed Database 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…

FF-1 Upgrade Continues, Preparations Begun for pB11 Operation

While FF-1 can’t fire until it gets the new tungsten cathode, the lab has not been sitting idle. The LPPF team has undertaken significant upgrades to the device, and started work on further ones. Other than a complete disassembly, cleaning and re-assembly of the vacuum chamber and drift tube to eliminate all sources of impurities,…

Tungsten Cathode Nears Completion after Long Delays

The long-awaited tungsten cathode is finally nearing completion in a Chinese factory.  According to the latest reports by California-based Tungsten Heavy Powder(THP), which is performing the work in China, machining will be complete within a few weeks and delivery to LPPFusion should occur by mid-February. The 99.95% pure tungsten piece has been in the machining…

Physics of Plasmas Publishes LPPFusion’s Runaway Electron Theory

Physics of Plasmas, the leading journal in the field of plasma physics, has published LPPFusion’s new paper on “Runaway electrons as a source of impurity and reduced fusion yield in the dense plasma focus”. The paper, by Chief Scientist Eric J. Lerner and Chief Research Officer Hamid R. Yousefi, was published online October 22, 2014…

Tungsten Anode Goes Into FF-1; Aluminum Cathode Model Is Checked

story2b

October 10, LPPFusion team members Eric Lerner, Hamid Yousefi and Tony Ellis lifted the tungsten anode into place on top of the FF-1 dense plasma focus experimental device (figure 1). The anode had previously been attached to its steel connecting plate (see September report) and was temporarily attached to a metal carrying rod for insertion…

Re-Assembly Begins of FF-1 with Tungsten Electrodes

The new tungsten anode has a current connection with the silvered steel plate at the edge indicated to by the blue arrow.  This current connection is below the red O-ring (yellow arrow) that seals the vacuum chamber indicated by the black arrow.  The old current connection was at the location of the red arrow, inside the vacuum chamber…

Nature Magazine Urges More Funding for Aneutronic Fusion

nature 200×200

In a July 23 editorial, Nature magazine has joined the calls to redirect fusion funding to aneutronic fusion—fusion that produces no radioactive waste. Speaking of the difficulties facing the ITER tokamak program, the editorial urged that, “Given these realities, the prudent course for the world’s funding agencies would be to support research into alternative fusion…

Tungsten anode has arrived

anodetungsten

The first of LPP’s new tungsten electrodes, the anode, or inner electrodes, is now complete and has arrived at our Middlesex, NJ lab. The electrode will contribute to greatly reducing the impurities that have prevented high density in our fusion-generating plasmoids. First, it connects to the rest of the circuit outside the vacuum chamber, eliminating…
