**Preliminary Budget for Materials for Two LYSO Crystal Based**Shashlik Matrices Each Composed of 25 Towers:Pb+LYSO and W+LYSO Harvey Newman & Ren-Yuan Zhu California Institute of Technology March 27, 2013 Meeting for Discussion of the Disposition of the Second Year Generic R&D Funding**LYSO/Pb & W Shashlik Cells**Rectangular towers consist of 2 mm thick LYSO crystal plates, 4 mm Pb or 2 mm W absorbers, and 0.15 mm Tyvekpaper layers. Each tower has 25 X0 length, 1.1 RM transverse dimension and about 25% sampling fraction. Readout with four Y11 fibers has about 0.5% light collection efficiency measured by a PMT with air-gap coupling. The Stochastic term is expected to be 9%. The total LO is comparableto PWO crystals with PMT readout. The LO would be higher with Si APD readout.**LYSO Plate Quotation**$45/$30 per 2 mm LYSO plate with holes for Pb/W cells respectively LYSO/Pb LYSO/W**Lead Plate Quotation**$23.5 per 4 mm Pb plate with 5% antimony + one time environmental disposal fee of $500 Lead Plate TyvekPaper**W Plate Quotation**$31 per 2.5 mm W plate with 95% W, 3.5% Ni and 1.5% Fe W Plate Tyvek Paper**Material Cost of 25 Cell Matrices**Cost estimates based on quotations received Total material cost is $ 98k = $ 52k + 46k for the two 25-tower matrices: LYSO+Pb and LYSO+W
