sPHENIX EMCal discussion

["Frantz, Justin" <frantz AT ohio.edu>]

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 

https://indico.bnl.gov/event/16280/

Topic: sPHENIX Calibrations Meeting

https://bnl.zoomgov.com/j/1617635022?pwd=WmlVME9tcnlTYnlkUC9nU3crNTdRdz09

Meeting ID: 161 763 5022

Passcode: 503420

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...

-Justin

Some tasks related to the pulse extraction fitting (urgent):

•-1) do for  Hcal:  repeat what has been done so far on that for EMC now for Hcal:  Tim Rinn now working on this

•-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, reevaluate some previous noise studies

Miscellaneous part 1

•-3) high pt eta meson simulation studies for fixing absolute EMC EM scale... embedded into MDC2  -- this was done by my student/postdoc Bing to a good degree but much needs redone with a different emphasis  1-person   see for example this talk  JS structure meeting March 2020 and subsequent eta meson EM scale constraint plots in S&C review March 2021 talk by Justin Frantz

•-4)  Medium pt electron E/p simulation study for constraining EMC EM Scale   1-person

•-5) DOCUMENTATION HELP FOR ALL MAJOR AREAS (could be a good task people could do as learning about it step)  X number of people needed

•-6) LED software experts for EMCal/Hcal  -- write up more of the automated software for incorporating the LED data in the calibration and the monitoring.   First part, writeup workflow and database entries and methods for initial state characterizations to be used as input to 1008 LED running.   - 2 people (3 including Hcal). 

•-7) tuning shower shape cut values for EMCal photons (can be used for pi0/eta meson calibration and other analyses. 1-person

•-8) Online monitoring:  decisions/software  2-4 people (at least 1 for EMc/Hcal--but over summer this may not be a full "FTE" yet

Hcal absolute scale calibration: (for background see workfest talks by Justin for Jan 2020 "Mega" workfest

linked here)

•-9)  (maybe? ) Event data PUNCH THROUGH (Inner hcal) / muon MIP  possibilities study for HCal EM Scale calibration  

•-10)  Isolated charge track hadronic shower studies (low priority)

Miscellanous Part 2

•-18)  (not needed till ~January?) Various zero suppression studies -- some of this could be started now, but that part may be already on the task list for JS topical group-

  -19)  (can and should be done very soon?)  Start testing/running/coding over Martin's test Hcal data file - needs Martin to checkin intitial code which is already written first.  

Miscellaneous other tasks people are already working on

•-11) finishing current pre-install cosmics+ testbeam Hcal EM / MIP scale absolute calibration tasks ?? :    Hanpu/Shuhang/Columbia/ Stefan etc...

•-12)  Pi0 Tower by Tower method and extensions  - Shyam / Ohio U

•-13)  General Pi0 Investigations with full sim:   Anthony Hodges

•-14)  Tower slope methodologies and implementation :  Blair Seidlitz and Justin Bryan

•-15)  Larger scale tests and framework  for data driven methods and beyond Justin Frantz and Chris Pinkenburg  (including tests of conditions DB)

       15 b -- revisit file formats 

•-16)  Finish pre-install EMCal Cosmics analysis/studies include KPP on cosmics calibration, uniformity: Tim, Hideki, Jingyu

•-17) Evaluate current performance/implement improvements/strategy for testing with real data: cluster position dependent response corrections.  Anne + UIUC students

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:
