Miniature Combination Ion PumpIon + NEG
Sputter ion pump + NEG getter in one · pumps without power · compact CF16
A miniature combination pump for ultra-high-vacuum (UHV) systems, integrating a sputter ion pump with a non-evaporable getter (NEG) in a single compact body: the ion pump removes inert gases and methane while the NEG absorbs hydrogen and active gases at high speed — complementary mechanisms that sustain UHV from a very small package. The NEG needs no power, so pumping continues during outages and transport. The getter activates at just 180 °C, so a normal system bakeout completes activation with no separate step. A matched controller and HV cable are included, delivering 2800~5000 V and reading vacuum in real time from the ion current (10⁻³~10⁻¹¹ Pa). The ideal main pump for magneto-optical traps (MOTs), neutral-atom quantum computers, optical clocks and precision measurement.
Key Features
Small size, high pumping speed — designed for space-constrained UHV systems.
Ion Pump + NEG in One
Two complementary mechanisms: the sputter ion pump handles inert gases while the NEG absorbs hydrogen and active gases at high speed — big pumping capability from a miniature body.
Activates in a Normal Bakeout
Getter activation at just 180 °C — your standard system bakeout activates it automatically, with no separate high-temperature activation step. Simpler commissioning.
Pumps Without Power
The NEG getter pumps hydrogen and other active gases with no power applied, holding vacuum through outages and system transport.
Matched Controller Included
Ships with a matched control power supply and HV cable: 2800~5000 V output, with real-time vacuum readout from the ion current (10⁻³~10⁻¹¹ Pa) — no extra gauge needed.
Compact & Lightweight
CF16 / CF25 flanges and a miniature, lightweight body for space-constrained systems, mountable in any orientation.
Works With LinQ Products
Pairs with LinQ's 2D-MOT, 3D-MOT and Mini-MOT cold-atom sources and alkali metal dispensers for a complete UHV cold-atom solution.
