[Esr-users] New Tool to review the ESR/HALLs A, B, C cyogenic system

[Dave Kashy]

Hi All,
With a lot of hard work by Nathan Baltzel of Hall B, we are now have a very preliminary version of the Tool that I was gathering signals for.
The idea I had was to be able to see if things are stable or something is changing at the most basic level. 
More experienced operators will be able to know more critical things such as if a specific system is one or off or overloaded etc. 


I just used it to spot that the Hall A lead flow have dropped ~50% since Hall C started its higher rate cooldown.

We (mostly Nathan) are still implementing lots of signals and improvements. 
One can see a preliminary web based version at:

https://hallbopi.jlab.org/webopi3.3/w

To get on you need to use your JLAB CUE user name and password.

In the top line (just below the web address) is an arrow down button where you can find lots of CLAS12 items.
The tool is listed under the Torus button for now, but we hope to find a better home for it in the future.

Click on the down arrow (triangle) and select "CLAS12_Menu-web.opi"
This brings up a new GUI and it has a button "Torus". Click that one.
Slide down to the tool. 
It is currently called "JLab Cryo Averages" 

The tool has 8 columns.
First is the signal name
Second is the Live reading from EPICS. It will show white if it is within the allowed value set up by the signal/system owner. If Alarms are set such as Low or Lolo or High or HiHi and it is out of range it will show as orange or red as needed.
Next are average value of that signal for different time ranges
Third is the 2 hr average 
Fourth is the 8 hr average
Fifth is the 24 hr average
Sixth is the 1 week average
7th is the units of the signal
and 
Finally 
8th is the Description of the signal


All of the averages also have alarms set on them. The values have currently been set my me and may not be appropriate. Many will need to be changed once we start to operate/power the magnets or targets. I hope we find a home for the epics page that all can access and set the proper time average alarms. 

Each average on the same signal has the same alarm value.

One can easily see if something major has changed over the last few hours, or shift or day or week by comparing the live value to the various averages.


For example right now one can see that the flow of the purifier CFI082 is nearly double the average of the last day and week but over the last 2 hrs it average has been ~ constant.
Looking closely one can track that to see that the Warm supply flow CFI6010 has more than doubled its 1 week average and so has CFI60DLP

One can also see that the lead flows of Hall A are taking a big hit because of this. To get those back up will require Cryo to put a back pressure on the 4K return of the Hall. And Heidi has requested David Schleeper to do this.

If one looks at the Hall B signals one can see that there has been no effect of the change in purifier flow. This can be seen by noting that the all the time averages 2hr, to 1 week are nearly identical.

Hall C does not have a significant number of signals implemented yet, so no change can be seen their either. 

At present there is no On-Call function based on this page and none is planned. It is a tool to look at to see who is changing what and help operators of different portions of the full system to more easily see what is going on as a whole.

IF signals or boxes turn purple there is a computer reboot going on or a communication error. There is also a box on the top line that shows "Comms error" if communications is not alive otherwise it says "Comms Ok"
On the top line is a box that 


Questions and comments welcome
I will post as more signals become available and when the system gets moved to a more permanent home.
ALSO,
Once again a BIG THANKS To Nathan!

PS, I was just about to send this and noticed that ESR just re-started the ESTL (4K boost to ESR) CFI6712.

CRYO Guys,

It would be appropriate for you to send an e-mail to esr-users at jlab.org when big changes like this are implemented, and a note about why.
Thanks
Dave
