There is nothing DSG can do regarding the configuration of the
computer in the newly completed NMR Rack #1.<br>
<br>
Rack #2 computer disk was originally built from the old Rack #2
HDice (non-CUE) Windows XP computer. This disk was upgraded to
Windows 7 in ~ 2015 as part of the work required to update LabVIEW
on the computer.<br>
<br>
When Rack #1 was being rebuilt this year, the computer disk was
updated to a Jlab-CUE based machine by the computer center. Any
change to the configuration or repair of the Rack #1 computer must
be done by the computer center.<br>
<br>
DSG has completed the installation of the NMR computers for Racks 1
and 2 in the HDice lab. So we will initiate a property transfer for
these machines to the HDice group.<br>
<br>
FYI: In the upcoming year, all Jlab Windows 7 computers (including
the NMR computers) must be upgraded by the computer center to
Windows 10. The required upgrade is detailed on the computer center
website here: <a moz-do-not-send="true"

<br>
Thank you very much for logging in the Rack 1 computer, now
I can proceed the shunt test.<br>
<br>
Here is my thought for the login issue: <br>
<br>
Both HDice NMR Racks will be used in several locations with
several cryostats interchangeably, and monitored by shift
takers during experimental periods. It is really important
that the 2 NMR computers were built the same way so we could
swap the racks without glitch. So far we, the HDice group,
could never successfully have computer center to build any
computer (for experimental or office use) without a lot of
connection constrains and biannual password changing. It
would be really hard keep track the login password of a
spare rack if it's not on the network for a while. It took
many months (and a few meetings with IT and their chain of
command) to re-config the IBC computer connecting to the
BlueJeans conferencing, after moving back to HDice Lab from
Hall-B. <br>
<br>
Could you please help us to rebuild the Rack 1 computer just
like the the one on Rack 2, with or without the DSG login?
We can provide the labors for that work.<br>
<br>
Thanks again for you time and help.<br>
<br>

Xiangdong,<br>
<br>
I logged into Rack 1 and there does not appear to be anymore
updates that are required. <br>
<br>
The Rack 2 computer was built differently than the Rack 1
computer. The Rack 1 computer was built by the computer
center and will require them to create a general account
that can be used by that computer. The Rack 1 computer will
not need to have the DSG login, as we can use the HDIce
login account when the computer center sets it up.<br>

</font><font face="Times New Roman">Hi Amanda,<br>
<br>
Would you please help me to login the HDice Rack 1 computer
and finish the windows' update?<br>
<br>
After finishing the updates, I'll contact IT group to change
the login mode so the HDice group can access the computer
after each reboot.<br>
<br>
Since the DSG setup the Rack 2 computer with two login
accounts, DSG and HDice, and it has been worked ever since,
is that easier for the DSG to setup the Rack 1 computer the
same way so the HDice group can swap those two racks
smoothly? Could you revisit this issue?<br>
<br>
Thanks again for your help.<br>
<br>
Best regards,<br>

<br>
Hi Amanda,<br>
<br>
Thank you very much for the message, I'll start playing the
new rack with the CT-Box. Could you please send the data
file for the two attached plots so I can do further
analysis? As soon as we cool down the PD-I (in ~1 week), I
will measuring the NMR the new rack.<br>
<br>
There is one setback:<br>
<br>
When preparing the PD-I in HDice lab yesterday morning, I
noticed that the display of control computer on the new NMR
rack was black. After stroking the SHIFT Key, the infamous
Windows Blue Screen shown up, indicating a computer crash
(see the attached picture IMG_3503).<br>
<br>
As you mentioned 2 weeks ago, this computer requires the
smart card to login (see attached picture IMG_3504), so I'm
stuck and need your help. <br>
<br>
Would you please:<br>
1). Investigate what caused the crash?<br>
2). Change the login settings to USING PASSWORD, so we
(the HDice group) can get access to the computer all the
time, especially in the night, weekends and holidays, to
measure the target polarizations while on shift? Given the
long and complicated target production process, the
reliability and accessibility of the NMR rack are extremely
important, which sometimes can become the only factor for
saving the target. <br>
<br>
Thanks again for the efforts you and the DSG group spent on
this project, we will always count on your support.<br>
<br>
Best regards,<br>
<br>
Xiangdong<br>

<br>
Averaging was implemented for the CT-box field values in the
NMR program and is ready to be tested. The program was run
for 1,000 cycles and the standard deviation of the field
values was analyzed. Attached is a zoomed-in picture of a
part of the average field values, showing the respective
points' standard deviation over the 1,000 cycles. The
average standard deviation was 0.55 G.<br>
