As the primary beam is incident with an angle of 45°, the primary time of flight will depend on the value of the x-coordinate.

E = \frac{1}{2}\cdot m_p\cdot v^2;\Rightarrow; v = \sqrt{\frac{2E}{m_p}}

\Delta t = \frac{\sqrt{2}}{2}\cdot x\cdot \sqrt{\frac{m_p}{2Q\cdot q_e\cdot E}}

where x is the x-coordinate (in m), mp, the primary ion mass (in kg) and E the primary energy (in eV), Q the charge number of the primary ion (1 of +, 2 for ++, etc.) and qe the charge of the electron
