HALO 201 MBE

The Hiden HALO RGA is designed for RGA, leak detection, trend analysis and vacuum survey in demanding MBE environments. The HALO 201 MBE features a contamination resistant ion source screen and molybdenum wiring in place of standard copper wiring.

The HALO quadrupole analyser is a precision assembly including a mass filter with machined radial ceramic supports, an electron impact ioniser with twin oxide coated iridium filament and Faraday and Channelplate electron multiplier detector. The analyser mounting flange is a DN-35-CF (2¾”, 70 mm OD) Conflat type flange. Mass range is 200 amu.

The HALO 201 MBE RGA is directly controlled from a PC compatible computer via USB, RS232 or Ethernet link, providing simultaneous data acquisition from multiple systems. The RC interface unit is a 90 mm high (2U), 19 inch rack mounting unit.  It is mains powered and includes power on and filament status indicators.

Windows® MASsoft Professional PC software provides for fast data acquisition through either user configured acquisition files or pre-set modes selected by icon.

Hiden manufacture a broad range of quadrupole mass spectrometers addressing a wide application range. Further RGA instruments are detailed in the Hiden RGA series specification.
