Description
The world-leading high-density UCN source developed for the TUCAN EDM experiment provides the statistical foundation for reaching improved sensitivity to the neutron electric dipole moment. With increased UCN density, the TUCAN collaboration aims to reach a statistical sensitivity at the $\sim 10^{-27}\ e\,\mathrm{cm}$ level in an initial measurement campaign. To realize this goal, the statistical reach of the source must be matched by a detailed understanding and control of systematic effects in the TUCAN EDM experiment, together with other experimental factors that influence the final sensitivity.
This contribution discusses the development of a systematic uncertainty budget for the TUCAN EDM experiment during the current construction and commissioning phase. The main sources of systematic uncertainty and the relevant corrections for a first $\sim 10^{-27}\ e\,\mathrm{cm}$ level measurement are outlined, and the corresponding technical requirements are discussed. This helps identify the parameters most relevant for the first measurement and guide further developments needed to fully utilize the potential of the TUCAN source.
