The detector was mounted so that its central hole is at the height of the electron beam while the TAC is in its parked position below the lead brick wall that shields it from the direct photon beam. It was then horizontally scanned across the beam by moving the TAC left and right.}}{2}{}} \newlabel{alcovephoto}{{1}{2}{}{}{}} \@writefile{toc}{\contentsline {section}{\numberline {II}Results from the 2007 tests}{2}{}} \@writefile{lof}{\contentsline {figure}{\numberline {2}{\ignorespaces Current measured on the two inner wedges of the active collimator as it was scanned horizontally through the beam.
