Technical Datasheet Radial Sample Distribution RTTA 3-Axis Rotarytelescopic extension with lift/lower) (Rotary & Source Shutters The 3-axis RTTA provides 360o rotation, 760mm linear extension and Z shift to provide arm lift/ lower to aid in sample transfer. Less than 1mm deflection at full arm extension with 10N load, linear reproducibility of <0.1mm and rotational reproducibility of <0.2mRad. Motorization options available. The RTTA has been designed to provide an alternative to traditional radial distribution sample transfer devices. The unique patent pending mechanism provides unrivelled extension and exceptional linear and rotary reproducibilty for the minimum system footprint. A high torque MagiDrive (see section 1) provides an extremely stiff coupling for the radial motion (Axis 1) acheiving angular reproducibility of <0.2mRad. A secondary MagiDrive is used to drive the arm in and out of satelitte chambers with a linear reproducibility of <0.1mm when fully extended. The addition of a Linear Shift Mechanism (see section 8) provides arm lift/lower to aid in sample transfer. Using high torque magnetically coupled drives to provide arm rotation and extension provides an inherently clean and robust operation.
