Challenge 1 – IFMIF-DONES
How can a system be developed for continuous monitoring of position and rotation of solenoids and SRF cavities inside a 4.5 K cryomodule over a 30-year lifetime?

Requirements:
·      Accuracy: ±0.1 mm and ±1 mrad
·      Maximum heat load: <1 W per component at 4.5 K
·      Radiation tolerance: up to 10⁵ Gy accumulated dose
·      Low magnetic permeability
·      Operation inside 4.5 K thermal shield
·      75 elements to be monitored

Background:
The cold mass string, up to 7 m long, consists of superconducting solenoids and half-wave resonator cavities. Existing technologies in other accelerators face limitations regarding heat load and long-term robustness.
