Ion Source Options

A range of ion source options for residual gas analysis

Hiden produces a wide variety of ion source types which can be fitted to our full range of RGAs. Ion source types are crucial to the performance of an RGA and having the ability to specify which source you require ensures our RGAs are custom configured for specific applications.

🛑 Overview

Standard RGA A radially symmetric configuration for general applications

UHV Low Profile Optimized for UHV TPD Studies enabling closer proximity of the ion source to the evolution surface

Closed Source For high pressure studies with direct gas input used in conjunction with a differential pumping stage for the analyzer

XBS Cross Beam Configured specifically for MBE deposition rate monitoring and control

Basic Cross Beam Used for analysis of molecular beams, where the beam may be liable to condense on ioniser surfaces. The source features an unobstructed pathway through the ionizing region of the source. External shrouds are available to protect the quadrupole mass filter from condensing species

Laser Cross Beam Source Includes two orthogonal unobstructed pathways for laser proton ionisation within the source cage region, providing an alternative to electron impact and electron attachment ionisation

4 Lens Ion Optics with Integrated Ioniser Additionally enables analysis of low energy positive and negative ions generated externally to the analyzer. For electron, photon and laser stimulated desorption studies

Platinum Ion Source This source is configured for improved operation in reactive gases. Radially symmetrical, UHV compatible

Gold Plated Ion Source This source is configured to minimize the effects of source outgassing. Radially symmetric, UHV compatible. Available as Standard or Low-Profile options
