Pinhole camera effects
Smudge or plasmoid? The crew develops the film from the X-ray pinhole camera.
LPP Experiment
Lawrenceville Plasma Physics (LPP) has embarked on a Two-Year Experiment to test Focus Fusion, i.e., Hydrogen-Boron Fusion using the Dense Plasma Focus. Here you can find reports on the progress of Focus Fusion, including past experiments, fundraising hurdles, and the current two year series of experiments.

Progress with Time of Flight Detectors
As with the PMT detectors, LPPX’s time-of-flight detector noise problems were also resolved.
X-ray PMTs reveal more than 60 keV electron energies, triple pulse structure
The following is from the LPPX July Focus Fusion report. For the laypeople reading this, a PMT is a photo-multiplier tube. Here are some pictures of various PMT‘s (they’re used throughout the lab). Once we get adequate resources, we will make describing the purpose and operation of PMTs and other instruments a priority. For now, here’s LPPX’s technical writeup:
Decaborane and the Vacuum System
Murali and Alex discuss the effects of decaborane on the vacuum system.
Decaborane Handling Issues: Design Modifications for pB11 Fusion Research
LPPX is starting to plan for the modification of the chamber to use the decaborane gas. For this purpose, the chamber has to be heated and has to be maintained at 100-120oC to keep the decaborane gas from condensing. A separate chamber is needed to store the solid decaborane. Several other design modifications are required such as protection of the pumping system against fouling by boron particles.
Below is an email string that addresses issues related to decaborane handling.
ICCD Camera
The following are some images of the ICCD camera used by LPPX. For a look at what the camera sees, check out this post about ICCD plasmoid image. And to help us flesh out a discussion of the instruments, visit the new wiki.
First ICCD image of plasmoid at FF-1
On June 30, LPP got their first ICCD camera image of a newly-born plasmoid.
