As I started the internal temperature test using field sweep, I found out
that actually the pickup coils at target chamber did see signals from the
target chamber, therefore I moved the target to pickup coil location so
that we can got NMR signal from both pumping chamber and target chamber!

Laser Power: 3x25W COMET
Oven Temperature: 230
Field Direction: Transverse -
Pumping direction: Parallel
Pumping Chamber Pickup Coil: Vertical
Sweep interval: 15 minutes
Data directory: C:\HappyValentine\NMR\Data\NMR_He_20090117_120928
