The LT-STM is specially customized to adopt optical\n components that are cooled to 4K and also adopts a 1K cooler for cooling superconducting\n SNSPD detector - operating at 0.9K. The aim of the research is to investigate molecular\n ices formed at interstellar conditions, including measurements of their characteristic\n fingerprints by detection of infrared emission from vibrationally excited constituent\n molecules.
The structure of polar molecular ices formed on e.g. graphitic surfaces\n are predominantly governed by the intermolecular interaction with a very weak interaction\n between the molecule and the substrate. Such weakly bound systems are known to be\n easily perturbed by the STM tip during the measurements. To avoid this, we demand\n a 4K STM setup with the capability to perform experiments with extremely small tunneling\n currents - down to 1pA. Another key requirement of the setup is the ability to provide\n a low temperature platform for detection of infrared (IR) light emission (down to\n 20um wavelength) from the tip-sample junction. The IR light is generated by deexcitation\n of vibrational modes in molecules primarily excited by the tunnelling current. Therefore,\n an extremely low count rate of photon emission is expected. It is thus of fundamental\n importance to have all optical components in the path from the tip to the detector\n cooled down to 4K. Consequently, the setup must accommodate and cool down to 4K a\n customized IR spectrometer as well as a separate 1K cooler for cooling superconducting\n SNSPD detector down to 0.9K. Considering high prices of liquid He a closed cycle system\n is needed to ensure continuous operation.
The unique technical specifications\n of the systems are as follows:
- closed cycle low temperature UHV STM system operating\n down to 4K
- operation below 1pA tunnelling current
- free volume space inside\n 4K shield for integration of customized spectrometer, SNSPD detector and a 1K cooling\n stage (minimum free space dimensions - 130 mm diameter, 195 mm height)
- Adaptation\n of the 4K and 80K shields for the operation of a 1K coller down to 0.9K
- two\n motorized parabolic mirrors maintaining focus to the tip-sample junction
- o high\n frequency cabling (in GHz range) for the SNSPD detector
- four separate ports\n for deposition of molecules into STM

A basic setup\n consists of a UHV compatible closed cycle LT-STM with integrated 1K cooler, free space\n for integration of spectrometer under the 4K shield and integrated UHV chambers for\n cleaning and loading samples. The necessary technical requirements are as follows:\n

ScientaOmicron is the only\n commercial supplier that can deliver a complete LT-STM that can fulfill all the essential\n requirements of the project.\n \n 6.1 Result lot ldentifier: LOT-00006.1.2 Information about winnersWinner:Official name: Scienta Omicron GmbH\n \n Tender identifier: 2025-0897314\n Identifier of lot or group of lots: LOT-0000\n Value of the tender: 1.000.000 Euro\n \n Contract information:Identifier of the contract: 2025-0897314\n Date on which the winner was chosen: 22-09-2025\n Organisation signing the contract: Aarhus Universitet\n \n \n \n \n \n 8 Organisations8.1 ORG-0001Official name: Aarhus Universitet\n Registration number: 31119103\n Postal address: Nordre Ringgade 1 \n \n \n Country subdivision (NUTS): Østjylland (DK042)\n \n Contact point: Jens August Aastrup Munch\n \n \n Internet address: https://www.au.dk/\n Roles of this organisation:\n Organisation signing the contract\n Organisation whose budget is used to pay for the contract\n Organisation executing the payment\n \n \n 8.1 ORG-0002Official name: Klagenævnet for udbud\n Registration number: 37795526\n Postal address: Toldboden 2 \n \n \n Country subdivision (NUTS): Vestjylland (DK041)\n \n Contact point: Klagenævnet for udbud\n Email: klfu@naevneneshus.dk\n \n Information exchange endpoint (URL): https://erhvervsstyrelsen.dk/klagenaevnet-for-udbud\n Roles of this organisation:\n \n \n 8.1 ORG-0003Official name: Konkurrence- og Forbrugerstyrelsen\n Registration number: 10294819\n Postal address: Carl Jacobsens Vej 35 \n \n \n Country subdivision (NUTS): Byen København (DK011)\n \n Contact point: Konkurrence- og Forbrugerstyrelsen\n \n \n Information exchange endpoint (URL): https://www.kfst.dk\n Roles of this organisation:Organisation providing more information on the review procedures\n \n \n 8.1 ORG-0004Official name: Scienta Omicron GmbH\n Postal address: Limburger Strasse 75 \n \n \n Country subdivision (NUTS): Limburg-Weilburg (DE723)\n \n Roles of this organisation:\n Winner of these lots: LOT-0000\n \n \n 8.1 ORG-0005Official name: Mercell Holding ASA\n Registration number: 980921565\n Postal address: Askekroken 11 \n \n \n Country subdivision (NUTS): Oslo (NO081)\n \n \n Email: publication@mercell.com\n \n \n Internet address: http://mercell.com/\n Roles of this organisation:\n \n \n \n Notice informationNotice identifier/version: 6be3bf0c-b657-469a-809e-f16a518c3e93 - 01\n Form type: Direct award preannouncement\n Notice type: Voluntary ex-ante transparency notice\n Notice dispatch date: 23-10-2025 10:45 +00:00\n Notice dispatch date (eSender): 23-10-2025 10:47 +00:00\n Languages in which this notice is officially available: English \n Notice publication number: 00704075-2025\n OJ S issue number: 205/2025\n Publication date: 24-10-2025\n \n \n","opsummeringDA":{"card":{"titel":"Direct award of Low temperature scanning tunnelling microscope - 2025-0897314","ordregiver":"Aarhus Universitet","ordregiverId":"ORG-31119103","ordregiverIdDatavasket":"31119103","publiceringsdato":"2025-10-24+02:00","cpvKode":"38000000","cpvTitel":"Laboratorieudstyr, optisk udstyr og præcisionsudstyr (ikke briller)","formulartype":"Forudgående underretning om direkte tildeling","formulartypeKode":"dir-awa-pre","tidsfrister":[],"alleOrdregivere":["Aarhus Universitet"],"beskrivelse":"Aarhus University wishes to buy a closed-cycle low temperature scanning tunnelling microscope (LT-STM) for a new experiment that will be established for structural and optical studies of molecular ices.
