sPHENIX HCal discussion

[John Lajoie <lajoie AT iastate.edu>]

Hi Jin,

    A very pretty poster!  Some comments:

Abstract:

"as we speaking" -> "at this moment"

"projection" -> "projections"

Design:

Consider putting a border around the text box associated with the text on the RHS.  It looks too closely associated with the Radius numbers to the immediate left.

If Eric's and Martin's posters have a numerical identifier or poster number, use that so they are easier for the interested reader to find.

Simulation:

Same comment as above about additional posters

Prototypes...

Maybe an arrow showing the beam direction on the prototype photo?

Overview...

"Follow more stories..." ->  "For more on the prototype and test beam results..."

Hello everyone

Please find a draft poster for " Design and test-beam performance of the sPHENIX calorimeter system " as on the following link:
https://www.phenix.bnl.gov/phenix/WWW/publish/jinhuang/Meetings/2017.02.06%20QM/sPhenix_QM17poster_calo.pdf 

Comments and suggestions the next three days will be appreciated. I will continuing refining the poster in meanwhile and printout later in the coming week. 

Cheers,

Jin

Hello Everyone,

Thanks for the suggestions from John and Eric. I have prepared a calorimeter
talk abstract as following. I also hope to coordinate with collaborators
regarding adjustments and submission.

Design and test-beam performance of the sPHENIX calorimeter system

The sPHENIX Collaboration at RHIC is planning a major upgrade to the
PHENIX experiment by constructing an entirely new spectrometer based on
the former BaBar solenoid magnet that will enable a comprehensive study of
jets and heavy quarkonia in relativistic heavy ion collisions. The sPHENIX
spectrometer will include one tungsten-scintillating fiber electromagnetic
calorimeter surrounded by two layers of steel-scintillator sampling hadronic
calorimeters, which will cover an acceptance of ±1.1 units in pseudorapidity
and full azimuth. The first prototype of this calorimeter system has been
tested at Fermilab in April of 2016, while the second prototype is taking data
in early 2017. Design considerations, test beam results and performance
projection for the sPHENIX calorimeter system will be presented in this talk.

Best regards

Dear all,
I would also like to submit an abstract on the HCal/testbeam. A drafted
abstract is below. I hope to coordinate the details with others. Best Regards,
-Megan

A Prototype of the sPHENIX Hadronic Calorimeter The proposed sPHENIX
experiment is designed to reconstruct jets in heavy-ion collisions at RHIC. A
crucial component to reconstructing the energy of jets is the sPHENIX
calorimeter system which includes electromagnetic and hadronic
calorimeters. The hadronic calorimeter (HCal) is a sampling calorimeter with
alternating layers of steel absorber and scintillating tiles.  There is an inner
and larger outer HCal, located inside and outside of the solenoid detector.
Prototypes of the EMCal, inner HCal and outer HCal were tested at the
Fermilab Test Beam Facility. Measurements of the energy resolution satisfy
the requirements of the proposed sPHENIX physics program and are
consistent with GEANT4 simulations. In addition to results of the test beam,
the tile testing and calibration procedure for the HCal will be discussed.

John-
I agree with your assessment of the calorimeter talks at QM.
In terms of electronics, I would suggest this for the electronics:
1. Front end (SiPMs/Analog section, including temperature and leakage
current compensation and slow control (Sean/Eric/Steve)
2. Digitizers/calorimeter trigger (Sara/Chi)
3. DAQ including tracking (Martin)
For the test beam results, I am wondering if we should not push for a talk
along with a posters focused on the EMCal and HCal analysis separately; Jin
for the talk and Virginia and Abhishek respectively for posters.
Ron and Vera would be natural for the HCal and EMCal detector construction
posters respectively.

Hello,

I think that we should cover all parts of the sPHENIX proposal in the
Quark Matter poster abstracts if possible; Tom had a nice organization
of the tracking-related abstracts, but the calorimeters have some holes
and inconsistencies.

I think the abstracts we want are these:

EMCAL detector
HCAL detector (including tile testing?)
Calorimeter electronics and SiPM's
Digitizer and calorimeter trigger
Beam test results

Data acquisition and triggering (including TPC, INTT, and MAPS)
Minimum bias trigger device?

Magnet? (low and high field testing, mapping, etc)?

Items with question marks are ones that I consider optional.
