sPHENIX discussion of electronics

[Ron Belmont <ron.belmont AT colorado.edu>]

Hi All,

Thanks to Eric for the suggestion, and indeed I would like to submit a poster abstract.  Megan and I will coordinate our posters.  My emphasis is on the construction and tile testing.

Title: Construction and testing of the sPHENIX hadronic calorimeter

Content: The planned sPHENIX experiment is a major initiative and a key part of the future of heavy ion physics in the US.  One of the key pillars of the planned physics program is detailed measurements of jets, which requires hadronic calorimetry over a large solid angle.  The sPHENIX hadronic calorimeter (HCal) is a sampling calorimeter comprising alternating layers of steel absorber and plastic scintillator.  In this poster we discuss the design and construction of the HCal prototype tested at the Fermilab Test Beam Facility in 2016 and implications for the final design, as well as detailed results on testing and characterization of the scintillators.

Regards,

Ron

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,

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.
