Paper Abstract

TNO, in cooperation with Micromega-Dynamics, SRON, Dutch Space and CSL, has designed a compact breadboard cryogenic delay line (figure 1) for use in future space interferometry missions. The breadboard (BB) delay line is representative of a flight mechanism. The delay line has a single stage voice coil actuator for Optical Path Difference (OPD) control, driving a two-mirror cat's eye. Magnetic bearings provide frictionless and wear free operation with zero-hysteresis. The development test programme, including operation at 100 K has been completed. The verification test programme is currently being carried out by Alcatel Alenia Space (in cooperation with Sageis-CSO) and will include functional testing at 40 K. A short design description and the intermediate results of the verification test programme are reported in this paper.
