Rb Schematic
Rb Vapour source – Key characteristics Parameter Assembled mass (kg) Estimation 240 kg (ex stand) Intended operating pressure 10 -6 m. Bar Max accessible surface temperature 60°C Max internal temperature 230°C Input requirements Electrical Power 230 v 50 Hz / 4. 5 Amp Compressed air 9 bar Oil Pressure 1. 2 bar
Rb Vapour source – Material characteristics Materials Purpose Mass Hazard UHV Assessment Exposed Stainless steel Chamber , pipes and valve bodies Low Bungs PEEK Low Copper Gaskets Low Aluminium Apertures Low Al alloy Adjuster plates Low Mild Steel Adjusters Low Calcium Silicate Insulation Moderate – dust irritation hazard if disturbed
Rb Vapour source – Material characteristics Materials Purpose Mass Rockwool Insulation Moderate – respiratory irritation hazard if disturbed Brass Adjusters Low Sapphire Windows Low Fluid media – Galden HT 270 Heating + Cooling Moderate – PPE required. Burn and fume hazard at high temp Valve gaskets Viton Low Mica Heater insulation Low Rubidium Vapour media <3 kg Hazard Assessment High
