  1. HCAL-J • Physics Design Optimization • Original JINR COMPASS HCAL design modified to obtain faster timing resolution. New design uses alternative scintillator and wavelength shifter (WLS) materials. WLS moved to center of module. • Optimal PPO concentration (0.5%) determined via measurements of FNAL supplied extruded scintillator coupled to WLS material. • St. Gobain BC-484 and Eljen EJ-299-27 WLS material tested with FNAL scintillator. BC-484 selected as optimal WLS. • Single element castable light-guide geometry designed with optical photon package of GEANT4. High transmission geometry achieved. • Prototype Construction and Detailed Design • Components tested and performance used to benchmark simulations • Detailed design (bolt placement, etc.) being finalized • Structural prototype (can, ribs, endplates…) being assembled. (Encountered some problems with manufacturer meeting specs.) • HCAL-J Construction • Scintillator production initiated (First shipment early 2014.) • P.O. for BC-484 placed by INFN (Bellini et. al.) • Light guide manufacturing to be initiated this fall. • Quotes for steel absorbers and modules must be updated prior to placing orders. • Construction scheduled determined by available funding.
