Gap Measurements:

1) Gap Measurements are made on one magnet at a time.
2) One program is used to make all gap measurements. Measurements are made at 36 positions along the magnets length. These measurements include:
a) Raw sensors voltage reads.
b) Raw and corrected "sensor to surface" data.
c) Calculated Gap, inside and outside pole locations.
d) Calculated Midplane Height, inside and outside locations.
e) Calculated magnet Roll Angle
f) Calculated magnet Gradient
3) The data is then summarized in 3 files:
a) GAPLOG.RU#
Contains the data collected during a gap run as described in 2)
b) GAPDAT.RU#
Contains a summary of the averages and standard deviations of the data described in 2).
c) GAPPLT.RU#
Is a summary table specifically used for a plotting routine to examine the data after a measurement. This is just a compressed summary of the data found in the summary file GAPLOG.RU#. It contains no headers, titles, of explanations of what the data is.
