Internet Course on 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
