Agilent VacIon Plus 1000 Ion Pump

Overview

The Agilent VacIon Plus 1000 Ion Pump is a high-performance, oil-free vacuum pumping solution engineered for ultra-high vacuum (UHV) and extreme-high vacuum (XHV) environments—typically defined as pressure ranges from 10⁻⁹ to <10⁻¹¹ mbar. Operating on the principle of ionization and sputter-ion trapping, this pump utilizes a strong permanent magnet field and high-voltage electrodes to ionize residual gas molecules, which are then accelerated into a chemically reactive cathode surface (typically titanium), where they are buried or chemically gettered. Unlike turbomolecular or cryogenic pumps, the VacIon Plus 1000 contains no moving parts, eliminating mechanical vibration, bearing wear, and hydrocarbon contamination—making it ideal for applications demanding long-term stability, electromagnetic quietness, and ultra-clean vacuum conditions.

Key Features

• Tri-element modular architecture: integrates optimized diode, triode, and inert-gas-enhanced diode pumping cells to deliver balanced, application-specific pumping speeds across H₂, He, Ar, CH₄, and other noble and reactive gases.
• Zero-vibration operation: absence of rotating components ensures compatibility with vibration-sensitive instrumentation—including electron microscopes, atomic force microscopes, gravitational wave detectors (e.g., LIGO-style interferometers), and particle accelerator beamlines.
• Low leakage current design: enables stable, low-noise pressure measurement when paired with Bayard–Alpert or extractor gauges—critical for reproducible process control and metrology-grade vacuum monitoring.
• Reduced magnetic field emission: engineered magnet geometry minimizes stray field interference with adjacent electron optics, mass spectrometers, or superconducting devices.
• Bakeable to >400 °C under vacuum: all internal surfaces are UHV-compatible; the pump undergoes in-situ vacuum baking and gate-valve sealing prior to shipment, ensuring pre-installed cleanliness and outgassing readiness.
• Flexible integration: supplied with a standard 12-inch ConFlat (CF-300) non-rotatable flange, plus auxiliary CF ports (dual-end and side port options), enabling multi-directional pumping configurations and custom feedthrough routing.

Sample Compatibility & Compliance

The VacIon Plus 1000 is compatible with stainless steel (316L EP), copper, and aluminum vacuum systems conforming to ISO 286-2 (H7/g6 fit tolerances) and ASTM F2789 (UHV component cleaning standards). Its construction meets ASME BPE surface finish requirements (Ra ≤ 0.4 µm) for critical research and semiconductor tooling applications. While not certified to a specific regulatory framework by default, its design supports compliance with GLP/GMP vacuum system validation protocols—including documented bakeout cycles, pressure rise rate testing (<0.1 mbar·L/s after 24-hr hold), and traceable calibration of integrated ion gauge controllers per ISO/IEC 17025 guidelines.

Software & Data Management

The pump operates autonomously without embedded firmware or real-time software control. However, it is fully compatible with Agilent’s 8700 Series Vacuum System Controllers and third-party PLC-based vacuum management platforms (e.g., MKS Instruments’ Sentron, Pfeiffer Vacuum’s TPG300 series) via analog 0–10 V or 4–20 mA interlock and status signaling. Integrated pressure readouts support audit-trail logging when connected to systems compliant with FDA 21 CFR Part 11 (electronic records and signatures), provided external data acquisition hardware implements required security controls (user authentication, electronic signatures, and immutable log archiving).

Applications

• Particle physics infrastructure: beamline vacuum maintenance in synchrotrons, storage rings, and linear accelerators requiring sustained XHV and minimal magnetic perturbation.
• Gravitational wave observatories: isolation chamber and optical path vacuum systems where sub-nanometer mechanical stability and zero electromagnetic noise are mandatory.
• Surface science instrumentation: XPS, AES, and molecular beam epitaxy (MBE) chambers demanding ultra-low hydrocarbon background and long-term base pressure stability.
• Quantum computing R&D: dilution refrigerator shielding and cold-finger vacuum jackets requiring bakeable, non-magnetic, and helium-leak-tight pumping solutions.
• Space simulation chambers: thermal vacuum test facilities where reliability, radiation tolerance, and absence of lubricants are essential for mission-critical qualification.

FAQ

What is the typical hydrogen pumping speed of the VacIon Plus 1000 at 10⁻⁸ mbar?
Hydrogen speed is cell-dependent; the diode module achieves ~650 L/s, while the triode and inert-gas diode modules provide ~500 L/s and ~700 L/s respectively—measured per ISO 3529-3 using calibrated capacitance manometers.
Can the pump be operated continuously at full voltage without degradation?
Yes—designed for continuous duty at nominal 7 kV electrode bias; lifetime exceeds 50,000 hours under typical UHV/XHV operating conditions with periodic pressure monitoring.
Is remote diagnostics or predictive maintenance supported?
No onboard intelligence exists; however, integrated current/voltage telemetry enables external trending of cathode sputter rate and gas load history—serving as an empirical indicator of end-of-life or contamination events.
Does Agilent provide installation qualification (IQ) or operational qualification (OQ) documentation?
Factory-issued UHV test reports (including bakeout logs, leak check results, and base pressure verification) are supplied; full IQ/OQ templates can be provided upon request for regulated environments.
Are replacement cathodes or refurbishment services available?
Agilent offers full pump rebuild services including cathode reconditioning, magnet recalibration, and flange surface re-polishing—performed at authorized service centers adhering to ISO 9001:2015 quality management standards.
