Simultaneous analysis of collinear neutron time-of-flight (nToF) traces applied to pulsed fusion experiment.

On pulsed fusion experiments, the neutron time of flight (nToF) diagnostic provides critical information on the fusion neutron energy spectrum. This work presents an analysis technique that uses two collinear nToF detectors, potentially to measure nuclear bang time and directional flow velocities. Two collinear detectors may be sufficient to disambiguate the contributions of nuclear bang time and directional flow velocities to the first moment of the neutron energy spectrum, providing an independent measurement of nuclear bang time.

Time-of-flight vs time-of-arrival in neutron spectroscopic measurements for high energy density plasmas.

The neutron time-of-flight (nToF) diagnostic technique has a lengthy history in Inertial Confinement Fusion (ICF) and High Energy Density (HED) Science experiments. Its initial utility resulted from the simple relationship between the full width half maximum of the fusion peak signal in a distant detector and the burn averaged conditions of an ideal plasma producing the flux [Lehner and Pohl, Z. Phys.

Sustained Neutron Production from a Sheared-Flow Stabilized Z Pinch.

The sheared-flow stabilized Z pinch has demonstrated long-lived plasmas with fusion-relevant parameters. We present the first experimental results demonstrating sustained, quasi-steady-state neutron production from the fusion Z-pinch experiment, operated with a mixture of 20% deuterium/80% hydrogen by pressure. Neutron emissions lasting approximately 5  μs are reproducibly observed with pinch currents of approximately 200 kA during an approximately 16  μs period of plasma quiescence.

Excogitating Bion's Cogitations: further implications for technique.

The author takes up a number of Bion's musings posthumously published as Cogitations (1992) and attempts to demonstrate the clinical usefulness of Bion's thoughts. She offers some new models and some points of technique that might be derived from following the trail of these selected fragments of Bion's thinking. Several detailed clinical examples are offered for clarification and illustration.

Trying to enter the long black branches: some technical extensions of the work of Frances Tustin for the analysis of autistic states in adults.

The author suggests a number of technical extensions/clinical applications of Frances Tustin's work with autistic children, which are applicable to the psychoanalysis of neurotic, borderline and psychotic adults. These are especially relevant to those individuals in whom early uncontained happenings (Bion) have been silently encapsulated through the use of secretive autosensual maneuvers related to autistic objects and shapes. Although such encapsulations may constitute obstacles to emotional and intellectual development, are consequential in both the relational and vocational spheres for many analysands and present unending challenges for their analysts, the author demonstrates ways in which it may be possible to detect and to modify these in a transference-centered analysis.
