2 Test stands for electrodes
F. Furuta et al., NIM A 538, 33 (2005) Vacuum of 10-11mbar Field gradient up to 170 MV/m Electrodes separation ~ 0.5mm Experimental voltage ~ 85 kV DC high voltage field emission test stand M. BastaniNejad et al., Phys. Rev. ST Accel. Beams 15, (2012) Vacuum of 10-12mbar Field gradient up to 20 MV/m Electrodes separation ~ 20-50mm Experimental voltage ~ 225 kV Tevatron electrostatic separator in the vacuum chamber Vacuum of 10-10mbar Field gradient up to 6 MV/m Electrodes separation ~ 30-50mm Experimental voltage ~ 180 kV

3 Clean room Clean room class ISO 7 (10.000)
special floor for a clean room frame structure of the walls antistatic curtain, furniture

4 Vacuum setup Scroll fore pump Turbo-molecular pump Ion getter pump
-> mbar -> 10-9 mbar -> mbar Atmosphere 10-2 mbar 10-9 mbar

5 High voltage setup 30kV power supply with fast discharge
30kV power supply with fast discharge Manual polarity reversion ARC-detection Rapid discharge circuit Common ground Current protection scheme Dark current measurements with picoammeter

6 Test electrodes Material : Stainless Steel Aluminum
d = 20mm d = 40mm d = 60mm Material : Stainless Steel Aluminum Treatment : Mechanical polishing and cleaning

7 Test electrodes result
Material : Stainless steel, Aluminum Mechanically polished and clean Stainless steel Two small half-spheres (R = 10mm) 17kV at 1mm distance → 17 MV/m Half-sphere vs. flat surface 12kV at 0.05mm distance → 240 MV/m Aluminum 3kV at 0.1mm distance → 30 MV/m
