The GlueX FCAL consists of 2800, 4 cm x 4 cm x 45 cm lead glass blocks stacked in a circular array. Each block is optically coupled to an FEU 84-3 PMT which will be instrumented with flash ADC electronics. GlueX-doc 985,988 and 989 document the GlueX Fcal as presented in the February 2008 Calorimetry Review.
