Gain Scan over anode wires for iTPC prototype #SD000

 Here shows the first complete scan on anode wire gain using Fe55 for prototype #000 (40rows) with all final design & materials, 3 points each wire.  The signal was read out using MCA+(pre)amplifier. The prototype 000 using final design strongback, pad plane and side wire mounts, and the assembly including MWPC was completed in January 2017.  The main work of this scan was done by Shiwei Bai, a senior undergraduate student.
