Danemarca – Simulator tehnic de cercetare, de testare şi ştiinţific – Low vibration, high vacuum cryostat, with vector magnet for SDU

Low vibration, high vacuum cryostat, with vector magnet for SDU / Qnity SAS The requested cryogenic system must meet a unique combination of optical, cryogenic, vacuum, vibration, electrical, and future upgrade requirements that are essential for our research. Following a market assessment, only the proposed supplier was identified as capable of providing a fully integrated system meeting all mandatory specifications. 1. Product Specifications Required The system must provide: • At least four lateral optical accesses and one top optical access. • A large cryogenic sample volume of Ø250 mm cold plate × 250 mm height. • Non-magnetic radiation shield with four horizontal and one vertical optical window. • Three integrated 50 A high-current channels to the 4 K stage. • Four thermally anchored coaxial lines for measurements up to 20 GHz. • Four fibre-optic feedthroughs. • 48 DC electrical connections at the 4 K cold plate. • Base temperature ≤ 3.5 K with stability better than 50 mK. • Cooling power of at least 250 mW at 4.2 K. • Vibration levels below 30 nm peak-to-peak. • Ultra-high vacuum better than 1 × 10⁻⁹ mbar. • Remote cryocooler architecture with unrestricted 360° optical access. • Future compatibility with a removable 4-1-1 vector magnet. • Complete mobility of the cryostat on the optical table. 2. Why These Specifications Are Necessary • Large 250 mm sample space: Required to accommodate complex optical setups, cryogenic positioners, electrical and fibre connections, and future magnet integration without redesigning the experimental platform. • Ultra-high vacuum (UHV): Our experiments run continuously for several weeks. A vacuum level better than 1 × 10⁻⁹ mbar is essential to avoid contamination of samples and optical windows, ensuring stable measurement conditions and reproducible results over long measurement periods. • Remote cryocooler and ultra-low vibration: Our experiments rely on interferometric and other vibration-sensitive optical measurements. The cryocooler must be physically separated from the optical table to minimise vibration and acoustic noise transmission, while maintaining the flexibility to move the cryostat when experimental configurations evolve. • Extensive optical access: Four side windows and one top window are required to provide simultaneous laser excitation, imaging, collection optics, and future experimental configurations that cannot be accommodated by standard cryostat designs. • Future magnet integration: The system must support straightforward integration of a 4-1-1 vector magnet and allow different magnet configurations to be installed or removed without major modifications to the cryostat. 3. Why There Is Only One Supplier The selected supplier is the only identified manufacturer capable of providing all required features within one validated and integrated platform. In particular, the supplier uniquely combines: • A Ø250 mm × 250 mm cryogenic sample space. • UHV performance (<10⁻⁹ mbar) suitable for multi-week experiments. • A remote cryocooler architecture delivering very low vibration while preserving cryostat mobility. • Unobstructed 360° optical access with multiple optical ports. • Integrated high-current, RF, fibre-optic, and DC measurement infrastructure. • A design specifically prepared for future vector magnet integration and compatibility with different magnet configurations. • Cryogenic positioners and cryostat supplied by the same manufacturer, ensuring full mechanical, thermal, electrical, and software compatibility while eliminating integration risks. Although alternative suppliers may offer some individual features, no other supplier was found that can simultaneously provide the required UHV performance, large sample volume, remote low-vibration architecture, extensive optical access, future magnet flexibility, and fully integrated cryogenic positioning system. We have nonetheless ensured that the terms of acquisition reflect sound financial judgment and serve the best interests of SDU and Danish taxpayers. Based on the market coverage, there is only one supplier who can deliver the desired equipment. The low vibration, high vacuum cryostat, with vector magnet can only be supplied by Qnity SAS because it is the only known commercial supplier of a system with these technical specifications. There is an objective and proportionate reason for the establishment of specifications which result in there being only one supplier. The possibility that there are other potential suppliers who could deliver the same has been objectively excluded by market consultations. I henhold til lov om Klagenævnet for Udbud gælder følgende frist for indgivelse af klage: Klage over ikke at være blevet prækvalificeret skal være indgivet til Klagenævnet for Udbud inden 20 kalenderdage fra dagen efter afsendelse af en underretning til de berørte ansøgere om, hvem der er blevet udvalgt, jf. udbudslovens § 171, stk. 2, eller klagenævnslovens § 2, stk. 1, nr. 1, når underretningen er ledsaget af en begrundelse for beslutningen. I andre situationer skal klage over udbud være indgivet til Klagenævnet for Udbud inden: 1) 45 kalenderdage efter, at ordregiveren har offentliggjort en bekendtgørelse i Den Europæiske Unions Tidende om, at ordregiveren har indgået en kontrakt. Fristen regnes fra dagen efter den dag, hvor bekendtgørelsen er blevet offentliggjort. 2) 30 kalenderdage regnet fra dagen efter den dag, hvor ordregiveren har underrettet de berørte tilbudsgivere om, at en kontrakt baseret på en rammeaftale med genåbning af konkurrencen eller et dynamisk indkøbssystem er indgået, hvis underretningen har angivet en begrundelse for beslutningen. 3) seks måneder efter, at ordregiveren har indgået en rammeaftale, regnet fra dagen efter den dag, hvor ordregiveren har underrettet de berørte ansøgere og tilbudsgivere, jf. klagenævnslovens § 2, stk. 2, eller udbudslovens § 171, stk. 4. 4) 20 kalenderdage regnet fra dagen efter, at ordregiveren har meddelt sin beslutning, jf. udbudslovens § 185, stk. 2. Senest samtidig med at en klage indgives til Klagenævnet for Udbud, skal klageren skriftligt underrette ordregiveren om, at en klage indgives til Klagenævnet for Udbud, og om, hvorvidt klagen er indgivet i standstill-perioden, jf. klagenævnslovens § 6, stk. 4. I tilfælde, hvor klagen ikke er indgivet i standstill-perioden, skal klageren tillige angive, hvorvidt der begæres opsættende virkning af klagen, jf. klagenævnslovens § 12, stk. 1.
