Sometimes you’ll the signal swing small negative before the big positive swing. I think the negative swing is due to an avalanche on an adjacent wire. In MWPCs this causes a negative induced pulse on the adjacent wire.

<p>the attached files show some examples of events with wave forms from the FMWPC<br>
detector.<br>
One example shows that there is still some noise at times.<br>
An other issue may be that some signals show significant voltage drops before the actual rise of the main pulse.<br>
same color means same wire chamber.<br>
