We observed a substantial increase of the scintillation light output lead tungstate (PbWO$_4$) at small incidence angle with respect to two main lattice axes. This reflects acceleration electromagnetic shower development that occurs in crystalline Strong Field. measured generated by $120$-$\mathrm{GeV}$ electrons and $10$-$100$-$\mathrm{GeV}$ $\gamma$ rays on thick samples. result deepens knowledge mechanisms crystal scintillators could pave way innovative accelerator- space-borne calorimeters.
