The Hiden Analytical process investigation and control range of systems have been extended by the addition of the XBS probe
Purpose-designed for condensable molecular beam monitoring, the Hiden XBS probe integrates a unique electron bombardment ioniser with the Hiden 3F series quadrupole system for simultaneous monitoring of multiple beam sources through a wide 70deg cone, at any predetermined position within this cone of acceptance.
Species-specific analogue signals are then used for beam intensity output to the user's source control modules.
Monitoring of condensable molecular beams with conventional mass spectrometer probes is restricted due to deposition of conducting or insulating films on critical probe insulator and electrode surfaces.
To circumvent this, the purpose-designed Hiden XBS probe is totally enclosed in a stainless steel shroud to inhibit probe contamination, with dual plane custom configured beam defining aperture plates dedicated to simultaneous monitoring of multiple molecular beam sources with no direct contact with internal probe surfaces.
The standard mass range of 320amu accommodates species up to and including As4, with the probe thermally protected from the radiant heat sources by integrated water-cooling of the enclosing shroud.
With the stainless steel bellows-sealed linear motion drive the probe can be fine-adjusted for optimum positional alignment and fully retracted to obviate substrate shadowing.
All vacuum materials are fully UHV compatible and bakeable to 300C, with copper surfaces specifically excluded from the construction.
