[dsg-hdice] HDiceNMR2 availability?

[Xiangdong Wei]

Tyler,

Thank you for timely responding, I really appreciate it.

Same as in the field scan NMR program, the temperature log is for determine the thermal equilibrium polarization of H, D and F in PD conditions, where temperature and magnetic field of the target are well defined. For IBC, since it's too complicated to integrate to data stream, the temperature measurements shouldn't be used (same as in regular NMR program).

When connected to PD-1 or PD-2 and the sensor readings are also used send warnings to operator only (since the magnet is in persistent current mode, which requires a complicated procedure and the full IPS control program to change the field, the fsNMR program leave the magnet alone). The 1st alarm warning will trigger manual intervention immediately. (We have 2 people live onsite now.) For the future, we will add the magnet control functions, and test thoroughly before implementing, when the machine is not busy.

Thanks,

Xiangdong

Hi Xiangdong,

I've added the basic cryogenic sensor logging to the fsNMR program.

What should the program do if the sensor readings go out of bounds?

In the previous NMR program, the NMR sweep was stopped and an email was sent to notify of the issue. For now, I'll make the fsNMR program do the same thing.

Okay, thank you Tom and Xiangdong.

I'll also take a look at the X and Y without background.

I'll let you all know when I'm done for the day.

Hi Tyler,

Xiangdong is in a meeting and asked me to log off HDiceNMR2 so you could
work on it. The PC is free for you to use now.
