The purpose of this document is to describe the proposed addition of a 1 meter air gap in the Meson Test secondary beamline to accomodate additional beam instrumenation to be used as the first trigger in a time of flight measurement. The air gap will be in between the quadrupole MT4Q6 and the vertical corrector MT5VT1. The accelerator division will facilitate the: removal of a 1.17 Meter section of 6 Inch beam pipe, the addition of 2 Titanium windows, and the reinstatement of a vacuum bypass that was historically used for this very purpose. The Minerva collaboration is building and installing the instrumentation using four scintillators to improve timing resolution. This will be documented separately before installation. This document only describes the air gap and vacuum windows.
