This setup shall be equipped with a superconducting NbTi split-coil magnet that allows for generating magnetic field of at least 7 Tesla. The magnetic field axis should be aligned horizontal, such that there are two optical beam paths possible: one along the magnetic field axis, and one perpendicular to it. The optical cryostat windows need to be transparent between 400 nm and at least 6000 µm (VIS range + 0,05-2.7 THz) over a temperature range of 2-300 K. The system should be equipped with a variable temperature insert to achieve temperatures at least in the range of 2 K to 300 K and allow for quick sample change. The sample stick should allow for sample rotation (polar) and height adjustment with a sample clamp suitable to mount 10 mm x 10 mm sample for transmission. The system should be compatible with additional optional equipment to extend the temperature range to temperatures above 300 K. The bid must include: - a spare set of all necessary filters and adsorbers for He-compressor and He-flex lines - a detailed technical description and documentation with drawings of cryostat, VTI and sample stick, magnet power supply, temperature controller, stray field map and a preinstallation planning guide and check list. Beside the fulfilment of the criteria described under 2. Performance quote of this Annex A, the scope of deliveries and services includes: - delivery at the place of usage according to DDP Dresden (Incoterms 2020) - Place of usage: FWI, Gebäude 707/105b, Bautzner Landstr. 400, 01328 Dresden - installation - FAT (factory acceptance test protocol)/SAT (site acceptance test) and OST (on-site customer training) - printed and pdf version of user documentation in English or German - 2yr warranty, remote support</div> <div class="h1">Interne Kennung</div> <div class="pre">LOT-0000</div>
