  • Continuous running in vacuum at high torque and step rates with AML drive
  • Bakeable to 200 °C
  • Step angle of 1.8°
  • Step angle tolerance of ±5%
  • Operational temperature range -65 °C to +190 °C
  • Embedded thermocouple or PT100 sensor
  • Open construction with all internal spaces vented
  • Open hybrid ceramic bearings, lubricated with NyeTorr® 6300 ultra-low outgassing UHV grease

Arun SMD210-1U Rack Mount Stepper Drive

The SMD210 Vacuum-Compatible Stepper Motor Drive is designed
to match AML UHV motors. Two motors may be driven sequentially
under host computer control or by an internally stored program.
Manual operation is also available from the front panel switches or
a hand-held joystick.

Features:

  • Drives 2 UHV stepper motors sequentially.
  • Advanced low-power drive techniques for minimum motor temperature rise and outgassing and maximum operating time.
  • Phase currents can be set from 0.1 to 1A in increments of 0.1A.
  • Holding torque can be controlled independently of dynamic torque under program control, to reduce power.
  • Full, half, ÷4, ÷8 step drive modes with automatic transition at user selectable speeds. (Stops on full step positions only. Micro-stepping used for control of resonance and smoother step transition.)
  • Thermocouple amplifiers (type K) for motor temperature indication, protection and control of motor bakeout.
  • RS232C interface for host computer control. Drive programs can be developed and run from the computer console (Remote Program Control) or downloaded for stand-alone operation (Internal Program Control).
  • Motors may be operated manually with the front panel ‘STEP’ switches or with a joystick. Single-step or multiple-step operation with smooth acceleration to the selected speed.
  • 3 user inputs for interaction with program execution, in addition to two “End of travel” inputs for each motor.
  • 3 user outputs for switching under program control.
  • Simple control language has many powerful commands which allow control of all aspects of motion or position. Conditional operation, loops and jumps are possible.
  • 1U high full-width, steel-cased instrument for easy rack-mounting.
  • Operates from 100 to 240V, 50/60 Hz supply.

Arun Ion Gauge and Controller

The AML AIG nude ionization gauge is a high-sensitivity UHV Bayard-Alpert gauge covering the vacuum range of 3×10-11 to 1×10-3 mbar and is intended for electron-bombardment degas. It has an NW35CF flange with individual glass compression seals, closed-end grid and a
choice of filament materials.

Features:

  • Wide measuring range 3×10-11 to 1×10-3 mbar
  • Replaceable twin Tungsten, Thoria or Yttria-coated Iridium filaments
  • Individual glass compression seal around each feedthrough pin are more economical and robust than ceramic, resulting in a less expensive and more rugged gaugehead, with the central collector pin inherently guarded against leakage currents by the grounded bulk of the flange
  • The molybdenum grid has a closed-end, light, rigid structure, resulting in high sensitivity. The XRay induced electron desorption current at the collector is minimised by geometry and screening
  • Connector pins are gold-plated, shrouded and polarized. Gold plating ensures that oxidation on the air-side cannot occur even after repeated bakeouts
  • Maximum bakeout temperature 450 °C. Sensitivity 19 per mbar for nitrogen. X-Ray asymptote 3×10-11 mbar
  • RoHS compliant

Arun Ion Gauge and Controller

Arun PV3 Pirani Gaugeheads

Pirani gauges detect the cooling effect of residual gas molecules on a heated filament. The rate of heat transfer to the gas is related to pressure and causes a change in the electrical resistance of the filament or the amount of power required to maintain it at constant temperature. The filament is normally connected in a bridge circuit.

Features:

  • Range: 200 mbar to 1 x 10-3 mbar
  • Intended for use in constant-voltage bridge circuits, which reduces the filament temperature and the rate of filament corrosion or contamination at high pressures
  • May be interchanged between any AML NGC / PGC series or equivalent controllers without recalibration
  • Integral 3-metre lead and connector
  • Extension cables do not affect the calibration
  • Mounts in any orientation
  • 200°C bakeable version available
  • RoHS compliant
