sPHENIX EMCal discussion

[Maxim Potekhin <potekhin AT bnl.gov>]

    Hello Bryan,
    
    This is one item on the page you sent the link to:
    
    ```
    (Not needed until ~ January)... Various zero suppression studies --
    some sort of this could be started now, but that part may be already
    the tast list for JS topical group
    ```
    
    Why is it not needed till January? Naively one may think that zero
    suppression may have an effect on the systematics.
    Is there any effort at all in that direction?
    
    Thank you,
    Maxim

All,

 

I have updated the wiki page ‘Calorimeter Code & Software’ with Justin Frantz’s updates according to his previous email. See the page here.

Hi all,

            (first of all, having a very bad day with this "technology"
            stuff,  please ignore last email which was sent
            automatically before it was even started when I did a
            paste-- thanks Office 365).
          
            
          
          
            Reminder again of our Calo Calibratoins meeting tomorrow at
            the new Tuesday time 10:30 am

            My bigger technology problem was that I was trying to put
            together this list of tasks on some web page, which I
            eventually tried the wiki for.  I was already late gettting
            to it, apologies, but then it was made later by major
            problems trying to edit the wiki..  Added lots of changes
            clicked Saved changes and they wouldn't save, eventually
            losing a bit of editing....other problems...such as
            currently, as far as I can tell what you get when you "Edit"
            the page, isn't consistent with what's being displayed--"
            here's the page:   https://wiki.bnl.gov/sPHENIX/index.php/Calorimeter_Code_%26_Software 
             also, anyone know how to add a new wiki page? anyone know
            how to link it on the left bar directly? (e.g. under sphenix
            detector?)   apparently I need more learning on this... any
            help would be appreciated... I was editing with my "Frantz"
            account which previously has successfully edited other
            pages.
          
            
          
          
            So leaving that aside for now, I'm sure I'll evenually
            figure it out but, in the meantime we will just have to
            settle for me just putting some of what I could recover of
            my edits in this email directly-- below,  the tasks lists as
            I had previously indicated....going through these or some
            fraction of , will be the first agenda topic tomorrow, and
            of course we are looking for people to sign up for high
            priority items.   And any additional task which we have
            overlooked please raise these before by a reply or bringing
            up also at the meeting tomorrow).
          
            
          
          
            See you tomorrow !!!   task lists below...

•-2) Study possiblities for and implement a fast and slow (ie full/real-thing) mockup of this for the simulation- 2 people

• 2a, c   (2a first) one for emc/one for hcal -- this is a very high priority item I realized it affects lots of other things like noise studies...)

                  •  -2b
                  when this is done
                    introduce rad-damage noise levels and study,

Subject: New Tues. 10:30 am permanent Calo Calibrations Mtg -- starting this coming Tuesday 6/21

 

Hi Calo Calibrations aficionado's!

                After polling and repolling and private communications,
                we finally found an OK permanent time that should be
                good through the Fall semester as well.  That time is
                Tuesdays at 10:30am-12noon.    We will switch to it this
                coming week for our first new meeting at that new time,
                Tuesday June 21, 10:30am.  Please mark your calendars. 
                  We will hold the meeting every week at that time for
                the foreseeable future.  
              
                
              
              
                This next meeting will continue our discussions of our
                plans and tasks--I will try to have this as just the
                first of two discussions on this, one at each of the
                next two meetings.   In the next couple days I will send
                out another reminder along with an updated list of tasks
                and possibly some other information so people will have
                a chance to look and consider ideas and tasks they may
                be interested in helping with.    Hopefully this can
                make this discussion a bit more efficient.
              
                
              
              
                We will still make time for some updates, but please
                plan to be efficient and keep those short since it's
                been a couple weeks--fyi unfortunately the polling
                revealed that this current week was particularly bad for
                many people, possibly partly because of SQM...that's why
                we just gave up on this week and went for the new
                permanent time  next week instead.  
              
                
              
              
                Here's the indico for the next meeting:
