sPHENIX is a new detector at RHIC.

Hi Hugo,

Thanks - to me it looks fine. Yes, I believe the comment on slide 5 was a note for us as we present it, not for some specific labelling to be added to the plot.

(Happy to iterate further if needed, but probably we should do it off the main sphenix-l list…)

Hi Dennis, 

Thanks for sending the notes. 

Concerning the TPOT presentation, I think I have accounted for all the comments on the figures and updated them on the indico page (together with the slides). Please have a look in case I missed something (https://indico.bnl.gov/event/20367/contributions/80318/)

Bade would like to have her poster printed at Los Alamos tomorrow before leaving to Texas, so it would be great if the plots could be approved before that. I will be available all day to implement last minute changes. 

Concerning the comment 

Slide 5 - important context: we can reconstruct tracks without the TPC to perform the needed space charge distortion corrections

I believe this is better said on the poster (and the support note) than the figure itself. Correct ? 

I'll update those accordingly

Best,

Hugo

Subject: [EXTERNAL] Re: [Sphenix-l] final timetable for the approval meeting today

 

Hi all,

Thanks to Anne for organizing the approval session, and to all the presenters and attendees.

I attach here my notes for the afternoon session (also attached to the top-level Indico:https://indico.bnl.gov/event/20367/attachments/49476/84478/minutes-sPHENIX-Aug30-2023-AfternoonApprovals.txt ) - any corrections welcome.

Dennis

Hugo:
Slide 4 - make it more clear that the left and right are for z and phi respectively 
Slide 4 - update date to today (not date that data was recorded)
Slide 5 - important context: we can reconstruct tracks without the TPC to perform the needed space charge distortion corrections
Slide 6 - add time units to x-title 
Slide 6 - add TPOT to label 

Thomas:
Slide 3 & 4 - details of how the trigger is implemented is responsible for the tracks bunched near central membrane 
Slide 5 - blue line stops short of red point - fix this 
Slide 6 (and others) - adjust colors of TPC volume (if feasible, on all plots) and improve how hits are drawn
Slide 6 - mask MVTX noisy channel hit 
Slide 10 - add label that linear fit is through MVTX+INTT+TPOT
Slide 10 (and others) - move logo to have less unused black space 
Slide 12 - add rotated view
Slide 13-14 - replace old ones silently 

JaeBeom:
Slide 3 - OK
Slide 4 - indicate somehow where Ch 1 vs 31 are - could be drawing of wedge with filled in regions, or use eta range instead of Ch numbers 
Slide 5 - move z_MBD range up near the other labels
Slide 5 - double check x vs y axes in the right plot
Slide 6 - message: how central-forward correlation at different eta ranges 

Benjamin:
Slide 3 - square aspect ratio, add label describing this 
Slide 4 - add label “diffuse laser test” or similar 
Slide 5 - needs to say sPHENIX, TPC, date, remove the red dots. Instead of Run #, say Laser, etc. 
Slide 5 - consider putting a threshold at >0.05e+6 to remove the many dark purple regions 
Slide 6 - do not discuss here - Simulation-only 

Hao-Ren 
Slides 5, 6, 8 - add label like “N^MVTXcluster = 30 event“, choose different color for open red marker, need date 
All sides - add small label indicating ideal geometry, coordinate with other MVTX plots 
Skip slide 7
Slide 8: indicate that the right plot is made only from a restricted region on the left plot
Slide 9: instead of the left plot, we will consider a new plot showing just the v_z^Candidate distribution for all tracklets 
Slide 9: for the right plot, need to be careful with intended message 

Dan
All plots: use official sPHENIX style macro !
Slide 3: add label that indicates Calorimeter Readout Electronics, add sampling time/frequency in x-axis. Add legend entry for black circles. Different line styles. Date on top. Make labels and titles larger.
Slide 4: not for approval 
Slide 5: do not state efficiency quantitatively at this point. Y-axis title, collision system + energy. No NBD values for now. 
Slide 6: need some labels - sPHENIX, what we’re looking at. “Outer” Hadronic Calorimeter. Do we need label for z-axis ? 
Slide 7: skip the plot on left (can use a similar one approved earlier), right plot is simulation only - follow up with relevant group
