“…The Chilean operation has begun implementing and developing diagnostics in a conventional PF configuration in order to characterize the neutron emission. Then, after getting the experimental expertise with SPEED2, new experiments in a quasistatic Z-pinch [64][65][66][67], gas puffed PF and wires array will be performed to extend the device capabilities. Also, SPEED2 and SPEED4 will be used in the development of applications for radiation pulses from hot, dense plasmas, including x-ray and neutron radiography, detection of substances and micro-radiography for applications to microelectronic lithography and diagnostics of nanostructures.…”

This paper includes a brief overview of the contributions and results of several groups working in plasma focus (PF) devices around the world in the last few years. In section 2 a summary of the most important results of the dense transient plasma research programme of the Comisión Chilena de Energía Nuclear is presented. An approach to an integrated vision of the present PF research status is presented in the next section. Some parameters that remain practically constant in PF devices that operate in a wide range of energies from 1 MJ to tens of joules are discussed. These parameters ('plasma energy density parameter' and 'drive parameter') are used as a design tool to achieve an ultra-miniature pinch focus device operating at energies less than 1 J. Preliminary results of such an ultra-miniature device are presented. Applications to non-destructive tests, detection of substances, pulsed radiation in biology and material sciences are also briefly discussed in this paper.

At present the Plasma Physics and Plasma Technology Group of the Comisión Chilena de Energía Nuclear (CCHEN) has the experimental facilities in order to study fast dense transient discharges in a wide range of energy and current, namely: I) energy from hundred of kilojoules to tens of joules, II) current from megaamperes to tens of kiloamperes. Also several diagnostics have been implemented. An overview of the work being carried out on dense pinch plasma focus discharges at the Comisión Chilena de Energía Nuclear is presented. The plasma energy density and scaling laws for the neutron yield are discussed. Possible applications of the radiation emitted are also discussed.

“…Soto of Comisión Chilena de Energía Nuclear (CCE, Santiago, Chile) presented results from several works made on different small PF and Z-pinch devices of medium and low energy level (including miniature PF devices with stored energies as low as 1 J [15]) on the investigation of energy scaling and neutron and x-ray emission. He also discussed the current situation with the large facility SPEED2 [16] after first shots were made with this device.…”

“…As for large facilities, side by side with the already described PF-1000, the SPEED2 device (4 MA in short circuit) has been reassembled and already tested in Chile. First results on current and voltage, as well as on laser interferometry and neutron emission measurements, have been presented to this meeting by L. Soto (CCE) [16].…”

Common research topics that are being studied in small, medium and large devices such as H-mode like or improved confinement, turbulence and transport are reported. These included modelling and diagnostic developments for edge and core, to characterize plasma density, temperature, electric potential, plasma flows, turbulence scale, etc. Innovative diagnostic methods were designed and implemented which could be used to develop experiments in small devices (in some cases not possible in large devices due to higher power deposition) to allow a better understanding of plasma edge and core properties.Reports are given addressing research in linear devices that can be used to study particular plasma physics topics relevant for other magnetic confinement devices such as the radial transport and the modelling of self-organized plasma jets involved in spheromak-like plasma formation. Some aspects of the work presented are of interest to the astrophysics community since they are believed to shed light on the basis of the physics of stellar jets. On the dense magnetized plasmas (DMP) topic, the present status of research, operation of new devices, plasma dynamics modelling and diagnostic developments is reported. The main devices presented belong to the class of Z-pinches, mostly plasma foci, and several papers were presented under this topic. The physics of DMP is important both for the main-stream fusion investigations as well as for providing the basis for elaboration of new concepts. New high-current technology introduced in the DMP devices design and construction make these devices nowadays more reliably fitted to various applications and give the possibility to widen the energy range used by them in both directions-to the multi-MJ level facilities and down to miniature plasma focus devices with energy of just a few J.
