Numerical Plasma Focus Experiments
This is a do-it-yourself course. You may do the
following course at your leisure; and submit the exercises to leesing@optusnet.com.au. When you
have submitted all exercises satisfactorily, a customized e-certificate will be
sent to you. The recommended course duration is 4-weeks.

The Program
(a)
Introduction to the Worksheet
(b)
Configuring the Numerical Plasma Focus Laboratory (UPFL)
(c) Firing
a shot in NX2
(d)
Studying the results
(e)
Exercise 1
(a) To
configure the code for the PF1000 using trial model parameters
(b) To
place a published PF1000 current waveform on Sheet 2.
(c) To
place the computed current waveform on Sheet 2 in the same Chart
(d) To vary
the model parameters until the two waveforms achieve the best match.
(e)
Exercise 2: tabulate PF1000 results
(f)
Self-fit Chilean PF400
(g)
Exercise 3: comparative tabulation of PF400 vs
PF1000. Discuss Physics.
The PF1000
parameters as originally published. Nominal Lo, no ro .
Fitting that case from scratch.
Exercise 4:
Self fit DPF78 with nominal Lo and no ro .
Add DPF78 to comparative
list.
Variation
of neutron yield with pressure; case of PF1000-from short circuit (very high
pressure), through optimum pressure to low pressure;
Exercise 5
Variation
of SXR with pressure; case of NX2- from short circuit (very high pressure,
through optimum pressure to low pressure) Exercise 6
Circuit
analysis: from short-circuit shot: given Co, measure T and reversal ratio f;
derive Lo, ro; Exercise 7
Scaling laws through numerical experiments. General discussion
