sPHENIX EMCal discussion

[Eric Mannel <mannel AT bnl.gov>]

Vera-

Nice abstract.  Found the second sentence references to the different radii a little confusing.  Might help to make it clear that the ~100cm radius is the radius of the detector and ala John H's comment, the Moliere radius is consistent with the expected shower size.  In the last sentence you might want to be a little  more verbose in what you are going to present along the lines of " we will present the physics potential of the spHENIX EMCal, the current status of  design and plans for validating  the design performance."

We have submitted a preliminary request for an extension of T-1044 at FNAL  test beam  facility (FTFB) to evaluate the next generation of EMCAL and HCAL modules for sPHENIX in the April-July   2016 time frame.  Presumably these modules will be part of that test.

Have fun at QM

Dear sPHENIX EMCAL members,

I would like to submit the following poster abstract for QM2015.

I would appreciate it if you would give me some comments and suggestions.

[Title]

Tungsten Scintillating Fiber EMCAL for sPHENIX

[Abstract]

The sPHENIX detector is a proposed new detector at the Relativistic Heavy Ion Collider (RHIC). The sPHENIX physics program focuses on jets and hard probes of the quark gluon plasma (QGP). The proposed design of the electromagnetic calorimeter (EMCAL), made of Tungsten powder and scintillating fibers, is designed to have a Moliere radius of 2.3 cm and a radius of about 100 cm for a resolution high enough to resolve single photons and electrons in the high multiplicity environment, and to identify photon jets. The $\eta$ and $\phi$ segmentation of the EMCAL is 0.024 x 0.024. This poster presents the current status of the project design and prototyping.
