sPHENIX HCal discussion

[pinkenburg <pinkenburg AT bnl.gov>]

Hi Craig,

I think we had this discussion last year about this claim of the first ever hadronic calorimeter at RHIC. We have the zdc's and we ran with the fcal which are hadronic calorimeters at RHIC. AnDY also had a hadronic calorimeter.

Dear All,
   We're planning to submit the following abstract to this year's IEEE 
NSS/MIC on our recent test beam results. Please let us know if you have 
any comments by the end of the day today.

The PHENIX Experiment at RHIC is planning a major upgrade that involves 
building an entirely new spectrometer based around the former BaBar 
solenoid magnet that will enable a comprehensive study of jets and heavy 
quarkonia in relativistic heavy ion collisions. It will include two new 
calorimeter systems, one electromagnetic and one hadronic, that will 
cover an acceptance of ±1.1 units in pseudorapidity and 2 pi in azimuth. 
The hadronic calorimeter (HCAL), which will be the first hadronic 
calorimeter ever used at RHIC, will be a steel plate and scintillating 
tile design that is read out with wavelength shifting fibers and silicon 
photomultipliers. It will be divided into two sections: an Inner HCAL 
situated inside the magnet and an Outer HCAL located outside the magnet. 
The electromagnetic calorimeter will be a SPACAL design consisting of a 
tungsten powder epoxy matrix absorber with embedded scintillating fibers 
which are also read out with silicon photomultipliers. Prototypes of all 
three calorimeter detectors have been built and tested in the test beam 
at Fermilab in April of 2016. Results from those tests, along with a 
detailed comparison to Monte Carlo simulations, will be presented in 
this talk.

Many thanks,
Craig
