Abstract
We present measurements of the angular distribution of re-emitted light from tetraphenyl butadiene thin films when exposed to \SI{128}{nm} light in vacuum. Films ranging from \SI{250}{nm} to \SI{5.5}{\micron} in thickness are measured. All films were fabricated by evaporation deposition on ultraviolet transmitting (UVT) acrylic substrates. Preliminary comparisons of the angular distribution to that produced by a detailed Monte Carlo model are also presented. The current shortcomings of the model are discussed and future plans briefly outlined.
