This proposal outlines the geometric principles governing the placement of key components in a VVS (Vacuum Veto System) and DMS (Detector Magnetic System) for optimal photon and electron detection. Key parameters include the strategic positioning of a photon veto at z=4360 to intercept created photons and the manipulation of electrons in a magnetic field. The final VVS is designed with a 103 cm radius CsI positioned 2300 cm downstream, ensuring effective analysis during particle interactions across specified z-coordinates.

Proposed Minimal Scheme for VVS and DMS Geometry Principles dictating placement:: - Photons created at z=4360 must hit a photon veto - Electrons bent at middle of magnet must hit a photon veto - Last VVS is placed such that 103 cm radius CsI is 2300 cm downstream Z=4660 Z=5410 Z=5760 Z=6010 Z=4360 Z=5010 = Vacuum Window = VVS module (Dashed line = Photon Solid line = Electron) = Analysis Magnet = DMS Chamber
