[449] Top-Loading Closed Cycle Refrigerator for Electrochemistry

The CCR delivery shall include: 1. Cryofurnace with a temperature range from 10 K to 500 K, mountable on ESS level 2 flange mount (ESS-3069220) [1], Figure 8 . 2. 1 sample stick. 3. A set of dismountable vacuum cans and thermal radiation shields adapted to neutron powder diffraction. Therefore, the material used in the main beam and diffracted beam paths shall be neutron-compatible, meaning only aluminium and vanadium are allowed. At a minimum, vanadium windows in the main beam path. 4. Temperature control electronics with at least 3 temperature readings (Cryocooler 2nd stage for diagnostic purposes; heat exchanger and sample). 5. Compressor and flex lines. 6. Transport trolley for cryofurnace and auxiliary equipment, able to be wheeled, craned, and moved by forklift or pallet jack. Options : - Separate quotes for 3 options: 1. Full coverage of scattered and main beam with vanadium windows. 2. Minimum Vanadium coverage with windows principally on the main beam path. 3. Aluminium-only tails. In addition there shall be quoted: • Spare standard sample stick suitable for 10 - 500 K • Additional 2 sample sticks capable of reaching 800K by local heating, with sample space evacuated.
