You are quite right Paul, I’ll amend
the minutes to reflect that
thanks

Launch study group -minutes of Jan 12th meeting
Jonathan,
in
the last line of your minutes you state that no suggestions were made regarding
an alternative to the EF launch metric. On the contrary I did make a
suggestion to use Mode Power Distribution or Mode Transfer Function. MPD
is the normalized mode group power as a function of normalized mode group
number. MTF is the normalized mode power as a funtion of normalized mode
number. Using either of these, it is possible to define a mask, similar
to a waveform mask, that defines the bondary between acceptable and
unacceptable power distributions. Instruments are available from multiple
suppliers that measure EF, MPD, MTF. I took an action item to provide
references to Lew and Jim for these, which I have done. Please reflect
this in the minutes.
Because
the MPD and MTF measurements provide power distribution as a function of modes,
it can be much more precise compared to EF which defines power as a function of
space. The present EF specifications can be converted to MPD or MTF masks,
but the boundaries would be very liberal. If one wished to hone-in on,
for example, a particular vortex launch, a portion of this passing EF space
would be selected that more precisely defined the vortex.
