ASPIICS/Proba-3 Meeting – 21 st January, 2016 –Torino (Italy) OPSys Sub-Systems – Vacuum Control Sub-System:  Composed by: 2-stages pumping system consisting of:  Two tri–scroll pumps of 500 l/minute each;  Two turbo molecular pumps of 2000 l/s each. The tri–scroll pumps bring the pressure from atmosphere to mbar. This first phase lasts about half hour. From this vacuum level, the chamber passes from the viscous or laminar regime to the molecular one. At that point, the turbo molecular pumps can be turned on. The turbo molecular pumps bring the pressure to mbar in dynamic vacuum condition hampered by the-out gassing from the internal coating of the chamber. The internal SPOCC pressure (the vacuum level) is monitored by 5 vacuum gauges located in the pumping section and in the test chamber.

ASPIICS/Proba-3 Meeting – 21 st January, 2016 –Torino (Italy) SPOCC Collimator: Optical Design Collimating mirror:  10 deg off-axis parabola  2000 mm focal length  160 mm diameter  EUV ML coating (to be applied)  The light trap behind the mirror suppresses set-up stray light and simulates a “dark corona”  A series of baffles ensure additional suppression of the set-up stray light
