I just want to bring the following page to this list's attention.
It's about recent cutting edge physics from the University of
Florida's National High Magnetic Field Laboratory:
I allow myself to quote Dr. Scott Hannahs, Chief of User Research
Instrumentation, Research Associate Instrumentation & Operations
from a recent contribution to info-labview, the traditional LabVIEW
listserv user forum. Scott himself runs info-labview and appears
occasionally on this scitech-list as well. Regarding the NHMFL press
release Scott explained among other things:
*********Begin quoting Scott Hannahs***********
''The measurement done at the National Magnet Lab was done with a
small AC current (order of nanoamps) and then voltage measurements
with a phase sensitive amplifier (lockin amplifier). The number of
electrical carriers in the semiconductor is controlled by a gate
voltage to tune the device. The data collection was all in LabVIEW
running on an Apple PowerMac over GPIB connection to various
voltmeters, lockin amplifiers, and temperature controllers.
Communication for control of the worlds strongest magnet (45 tesla)
was also a Labview program communicating over a serial port. Further,
the programs that control the power supplies, monitor and control the
cryogenics, and ultra reliable monitoring the magnet for malfunction
are also all Apple PowerMac computers running various versions of
LabVIEW.''
*********End quoting Scott Hannahs***********
Scott is the author of the LabvIEW code which is used to run the
sophisticated DAQ tasks and data analysis. I think that his work by
using NI's LabVIEW environment in this content would make a great new
Apple science story illustrating how NI-LabVIEW is used on the Apple
Macintosh platform to perform high level data acquisition in hard
sciences.
Great work Scott and thank you for tirelessly helping to push LabVIEW
on the Mac
