TITLE: Cryogenic x-y-z Positioner

Requesting Laboratory / Division / Group:

Communications Technology Laboratory Radio Frequency Technology Division Radio Frequency Electronics Group, 672.03

General Statement of Need:

NIST needs a low-power X-Y-Z positioning stage for direct use at 20 mK in a dilution refrigerator with accurate position encoding and a closed-loop controller. The stages must be usable at 20 mK and result in minimal heating of the stage, reducing warmup and keeping the time to cool the temperature of the mixing stage back to 20 mK as short as possible. The materials must be non-magnetic as superconducting circuits sensitive to magnetic fields will be tested.

The current NIST Dilution Refrigerator is designed for positioning stacks comprised of two attocube ANPx341/RES+/LT/HV - linear x-nanopositioners and one attocube ANPz101/RES+/HL/LT/HV - linear z-nanopositioner. The vendor must provide any mechanical adapters needed to fit their positioners into the already designed space in the dilution refrigerator, the electrical adapters needed to use the existing wiring currently installed in the NIST Dilution Refrigerator and any software required for NIST to control the positioning stack in the NIST LABVIEW control environment.

Current solutions are primarily based on piezoelectric positioners. The power P dissipated in piezoelectric positioners with a capacitance C and loss tangent tan(δ) driven by a sinusoidal signal with frequency f and RMS voltage V in the piezoelectric actuators is given by P = V2 f C tan(δ). If the positioners travel a step size ∆s during each cycle of the sinusoidal drive signal, the total time ∆t to move the positioners a distance d is given by ∆t = d/(f ∆s). Thus, the energy dissipation E required to move a distance d is E = P ∆t = P d/(f ∆s) = V2 C tan(δ) (d/∆s).

To reduce power dissipation at low temperatures to an acceptable level, NIST requires that the energy dissipated in the positioner per unit length of travel E/d = V2 C tan(δ) / ∆s be less than 40 mJ/mm at 4 K for a piezoelectric drive voltage V capable of exerting force of 100 g and drive speed of f ∆s > 0.1 mm/s.

In addition, the power dissipated at the positioner required to determine the position of each encoder must be less than 100 nW and the Z positioners used in the stage must be able to lift 100 g at cryogenic temperatures. Finally, the encoders and closed-loop positioning algorithm must be able to repeatably place each positioner within ±2 um.

Item Specifications and Quantities:

Item 1: Cryogenic x-y-z Positioner Quantity: 1 Specifications: 1.1 20 mm x and y travel range, 4 mm z travel range

1.2 Closed-loop positioning repeatability within ±2 um on all axes.

1.3 Non-magnetic materials.

1.4 Positioners and encoders designed to operate and meet

specifications to 10 mK and in high vacuum environment.

1.5 The energy dissipated in the positioner per unit length of travel

E/d = V2 C tan(δ) / ∆s is less than 40 mJ/mm at 4 K for a piezoelectric drive voltage V capable of exerting force of 100 g and drive speed of f ∆s > 0.1 mm/s.

1.6 The power required to determine the position of each encoder is less than 100 nW.

1.7 The Z positioners must be capable of lifting 100 g at cryogenic temperatures.

1.8 Positioners suitable for use in high-vacuum environment

without outgassing.

1.9 All screws, wiring and mounting hardware required.

1.10 The x-y-z positioner, possibly after being fitted with suitable mounting adapters supplied by the vendor, must fit into the existing NIST dilution refrigerator. This requires that the x-y-z positioner be a direct replacement for the current positioner stacks comprised of two attocube ANPx341/RES+/LT/HV -linear x-nanopositioners (see https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpx341reslthv-linear-x-nanopositioner ) and one attocube ANPz101/RES+/HL/LT/HV -linear z-nanopositioner (see https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpz101reslthv-linear-z-nanopositioner ). Thus, the x-y-z positioner stack must use the same screw pattern as the attocube stack to attach to the baseplate, occupy no more than a 45 mm x 45 mm footprint when centered in x and y. The top mounting surface of the z https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpx341reslthv-linear-x-nanopositioner https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpx341reslthv-linear-x-nanopositioner https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpx341reslthv-linear-x-nanopositioner https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpz101reslthv-linear-z-nanopositioner https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpz101reslthv-linear-z-nanopositioner https://www.attocube.com/en/products/nanopositioners/low-temperature-nanopositioners/anpz101reslthv-linear-z-nanopositioner positioner must be horizontal, have the same screw patterns on the top of the z-nanopositioner as the attocube z positioner to attach items being manipulated, and must be the highest point of the positioner stack. Furthermore, when fully retracted, the x-y-z positioner must not be any higher than 51

mm. The dimensions and hole patterns of the attocube positioners can be found in the pdf files ‘anpx341reslthv-linear-x-nanopositioner.pdf’ and ‘anpz101reslthv-linear-z-nanopositioner.pdf’ after pressing the download button on the pages cited just above in this specification item. (For convenience, these pdf files are included at the end of this document.)

1.11 The electrical connectors on the x-y-z positioner, possibly after adding an electrical adapter supplied by the vendor, must functionally identical to the corresponding electrical male PEEK connectors compatible with those used by attocube, which have part numbers 1021498 3-pin PEEK connector (solder point) and 1010784 ACC 5-Pin PEEK Connector (Soldering Point). These connectors have a 2 mm nominal pin spacing, a

0.47 mm nominal pin diameters and a 4 mm nominal pin lengths. There should be a two-wire differential drive line with a two-pin connector and a three-wire sense line with a three-pin connector for the sensor for each positioner in the x-y-z positioner stack. The drive and sense lines must be at least 28 cm long. A single 50 ohm coaxial line with female SMA connectors is also available for each of these positioners.

Separately Priced Components / Options / Services Item 2: Motion controller, software and cabling Quantity: 1 Specifications: 2.1 Offers closed-loop control of cryogenic positioners.

2.2 Must be compatible with current LABVIEW software

environment used in the NIST Dilution Refrigerator experiments. If the controller is not currently supported by the NIST software, the software supplied by the vendor must include LABVIEW software VIs needed for all motion functions and interfaces to allow for programmed motion through USB or over LAN in the LABVIEW environment. Currently supported controllers are the attocube ANC350 controller and the Renaissance NP-Drive controller.

2.3 Cabling with length of 1.85 m or greater to connect controller to the dilution refrigerator, possibly with electrical adapters supplied by the vendor, bringing control signals to a female DB- 15 or female DB-25 connector. A wiring diagram must be included to allow NIST to build an adapter box to connect the controller to the NIST Dilution Refrigerator wiring harness.
