This page illustrates the target operator's role and responsibilities. It first explains how a new Target Operator can access NM4, what training is required, and what monitoring they must do.
The following link directs to a General Training page that helps the Target Operator access the NM4 Experimental Hall.
General Training to Get Access at NM4
Please see the NM4 Control Room Layout:
See the layout of the target screens (left side) and the pictures of the Target-Related screens (right side).
1. Target TV
2. Fridge 2x3 (Strip Charts)
3. QT-Terminal
4. NMR Terminal:
The following section explains the NMR terminal, polarization, and NMR Signal and how to take a new baseline and data.
How do we create a New Baseline?
Click on the Baseline in the above Green circled area, and it will pop up a new window like the one below:
Click on Create a new Baseline. It will close this window and come to the Main Display. After that, follow the picture below to set the sweeps:
Insert 5000 at point 1 (Sweeps) and click at point 2 on 'One Point.' The baseline will be completed in around 324 seconds. You will see a new baseline at the bottom left of the above picture.
