[dsg-hdice] NMR power supply synchronization

[Amanda Hoebel]

Hi Dr. Sandorfi,

We are currently working on the synchronization program. Could you let us know your schedule for Rack #1 so that we know when we may begin the upgrade? We plan to use Rack #1 equipment to debug and test the synchronization program. 
 
Thanks,
Amanda

Hi Andy, 

It is our understanding that HDice is currently using the equipment in NMR rack #1 to verify the performance of the rack #2 which DSG as has already upgraded. 

As previously requested by the HDice group, DSG will upgrade NMR rack #1 upon completion of rack #2 testing. During the rack #1 upgrade, DSG plans to use the rack #1 equipment for the advanced debugging and testing phase of the shunt synchronization project. Because we were waiting for the test results for rack #2 and necessary equipment from rack #1, we had put the synchronization project on hold. 

We are happy to hear that the tests on NMR rack #2 has started. In Xiangdong’s July 28 th email, rack #2 was used to test a HDice eHD target cell with good initial results which outperformed rack #1. DSG has also completed debugging all NRM program issues that were reported during this testing. 

Is there a time table for completion of testing for HDice Control Rack #2?

Hi Peter,

As we spoke a few weeks ago, we will be needing to operate the NMR rack with
the shunt synchronized to the lock-in. You mentioned that was put on hold
last January while you dealt with other pressing jobs. Do you have a time
table for completion of this task?

Hi,

A new LED has been installed in the transformer box and the box was placed
back in the NMR rack.

Regards,
Amanda
