The manipulators feature two sample positions. One primary stage featuring the 5- or 6-axes motion, and a secondary 4-axes stage usually occupied by a reference pin (for evaporating with Au).

Closed Cycle Sample Manipulators

A Complete Range for High Resolution ARPES Requirements

ARPES

  • Lowest temperatures from < 4 K
  • 4 to 6 axes
  • No liquid Helium consumption
  • Counter heating for temperature control

These state-of-the-art cryo manipulators have proven ARPES performance and have 4 to 6 motorized axes. The closed cycle cryo manipulators have no liquid Helium consumption providing unlimited holding time and low operating costs while offering the lowest temperatures needed for high experimental energy resolution. With numerous options these cryo manipulators cover a complete range of experiments.

Lowest possible sample temperatures are necessary for ultra-high energy resolution setups. The Extreme 5-axes Closed Cycle Cryo Manipulator achieves guaranteed temperatures lower than 5K, including counter-heating capability. This low base temperature yields a minimal thermal broadening of 1.5 meV. This is ideally combined with a high energy resolution analyser, like the DFS30 and DA30, and a narrow bandwidth light source such as the VUV5k and VUV Laser.  

The samples are mounted on a flag style sample holder. The included counter heating and PID temperature control provide fast ramping and excellent temperature stability necessary to study temperature dependent phenomena such as superconduction.

More Information

Closed Cycle Versions

Lowest achievable sample temperatures depend on the cooling power and the number of axes. 

Cooling System

The closed cycle manipulator is quickly cooled down by switching on the included compressor. Starting from room temperature a sample temperature of 6 K is reached in 4-5 hours. 

Options

The primary stage can be complimented with a 4 axes secondary sample stage replacing the Au sample reference position. Options for back gating and with multiple electrical contacts allow to conduct in-operando measurements. 

Optionally an angular test device, YAG crystal for photon alignment, 2-slot sample parking station, or sample cleaving station can be mounted below the sample and outside of the cryoshield. Even an e-beam heating stage reaching up to 1000 K without effecting the primary stage temperature is available.
