2022-LS-304 - ACAN Dry Cryogen-Free Variable Temperature System

SFU has a requirement for a Dry Cryogen-Free Variable Temperature System.
It is SFU’s intention to award a contract for this source to ICEoxford Limited.

Submission of a Statement of Capabilities
Suppliers who consider themselves fully qualified and available to provide the system described in the ACAN within the specified time frame and budget, may respond with a Statement of Capabilities, in writing to the SFU contact identified in this notice, on or before the response deadline of this ACAN. The Statement of Capabilities must clearly demonstrate how the supplier meets or exceeds the minimum essential requirements.
The Statement of Capabilities must be submitted to laura_simonsen@sfu.ca

Minimum Essential Requirements
Any interested supplier must demonstrate by way of a Statement of Capabilities that the integrated system meets the following requirements at the price noted below within the time frame specified:

The proposed system must:

1. Cryostat with integrated VTI with 85mm sample space platform
2. Be able to reach temperatures of 1.5K
3. Include a water-cooled compressor and 20m helium lines
4. Have an automatic gas handling system to control needle valve, temperature controller and magnet power supply with computer control
5. Include a storage vessel for the recirculated helium gas to allow for zero consumption of helium
6. Include pneumatic isolation supports for cold head to reduce vibration
7. Include a recirculating system pump
8. Allow for sample probe to cool down from 300K to <2K in less than 60 minutes without additional user wiring or user heat load
9. Allow the cold probe to cool down from 300K to 1.5K in less than 8 hours without additional user wiring or user heat load
10. Maintain a temperature stability of ±2mK at 1.5K
11. Have four-channel temperature controller with drivers and software to allow for computer control
12. Include an internal split pair magnet with a horizontal (perpendicular to the sample boar) field of at least 2T to be integrated into the system
13. Include an appropriately sized magnet power supply
14. Supply all vacuum and high-pressure lines and valves
15. Supply all IO and power cables for the system
