+Hi Eric and Sam,
+
+Here is a link to files that I have saved from the Lecroy Wavesurfer
+452 (500MHz 2GS/s).
+
+http://darkmatter.bu.edu/~ainglis/lithiumChamberPulses/
+
+The two directories are as follows:
+
+- a digitized signal of noise from a single preamp (#1) in a single
+channel (#1 - which is just the farthest wire from the summing
+amplifier)
+- a series of signal readouts when providing the chamber with test
+pulses.  All of these readouts are from the summing amplifier. the
+file name format is that it lists the preamplifier used (these are the
+second generation preamplifiers - there is a number marked in sharpie
+on the upper left corner of each preamplifier), and the wires that
+they are placed on respectively (again, wire #1 being the farthest
+away from the summing amplifier, then the voltage of the pulse that
+was entered.
+
+I realize that this first attempt to pass signal information to you
+will probably be riddled with some ambiguities or problems that we
+need to get cleared up.  I might need to give you the total
+digitization scale for the voltage, although I thought it may be clear
+from the numbers how it digitized.  Let''s just take a look at these
+and see if there is a better way to pass things over.
+
+Right now we are getting ready for a run of the chamber with HV and an
+argon environment, so background, alpha, and neutron-lithium
+interactions will be forthcoming.
+
+Thanks,
+
