Atom OvenThermal Atomic Source
Yb / Sr / K / Ca metal atomic beam source · ≤680 °C · ≥10¹²/s · CF35 integrated
A thermal atomic beam source (atom oven) for cold-atom systems. It heats and evaporates a metal charge to produce a high-flux collimated atomic beam, serving the metal species that need thermal evaporation beyond rubidium and caesium — ytterbium (Yb), strontium (Sr), potassium (K) and calcium (Ca). With a 50 g crucible, a maximum operating temperature of ≤680 °C and a beam flux of ≥10¹² atoms/s, the CF35 flange integrates resistive heating and a vacuum power feedthrough in one unit, bakeable and UHV-compatible. Complementary to LinQ's alkali metal dispenser (Rb/Cs), it covers the metal species that need crucible thermal evaporation — alkaline-earth and alkaline-earth-like metals such as Yb, Sr and Ca, plus K — the ideal source for Yb/Sr optical clocks, neutral-atom quantum computing and cold-atom precision measurement.
Key Features
Built for the metal species that need thermal evaporation — beyond Rb and Cs.
Broad Metal Compatibility
A metal atom source for Yb, Sr, K and Ca — covering alkaline-earth and alkaline-earth-like species (plus alkalis like K) that need thermal evaporation beyond the Rb/Cs dispenser, with other metals available on request.
High-Flux Collimated Beam
Beam flux ≥10¹² atoms/s with a collimated crucible nozzle for a low-divergence atomic beam — directly improving downstream MOT loading.
Precise Temperature Control
Maximum operating temperature ≤680 °C with thermocouple closed-loop control — a stable, controllable evaporation rate and repeatable beam flux.
Integrated Flange
A CF35 flange integrates the crucible, resistive heating and a multi-pin vacuum power feedthrough — plug-and-play, simple wiring, clean commissioning.
Large Crucible
50 g crucible capacity supports long continuous operation, reducing refills and chamber openings.
Low-Magnetic & Clean
Low-magnetic stainless-steel construction, UHV-compatible and bakeable — leaving the central magnetic field and measurement background undisturbed.
