Danmarks Tekniske Universitet - DTU

DTU requires the delivery of a turnkey, highly stable, and mutually coherent dual-comb light source with a broad spectral tuning range covering the near- to mid-infrared. The system shall be capable of generating femtosecond pulses at high repetition rates. The proposed solution shall consist of a tunable optical parametric oscillator (OPO) pumped by a dual-comb laser. The OPO shall provide continuous spectral coverage in the mid-infrared range from 2300 nm to 4200 nm and in the near-infrared range from 1500 nm to 1700 nm, while simultaneously providing output of the pump dual-comb. The system shall be installed at DTU Electro within the Optical Sensor Technology group. The delivered solution shall be fully integrated, user-friendly, and suitable for operation by multiple users. It shall support a wide range of applications, including but not limited to precision molecular sensing, rapid pump-probe analysis, hyperspectral imaging, and advanced semiconductor and photonic chip characterization.

DTU will like to buy a Laser Frequency Comb for 2ES (The Second Earth Spectrograph). The Second Earth Spectrograph (2ES) is a next-generation extreme-precision radial velocity spectro-graph that will be installed at the MPG/ESO 2.2m Telescope on La Silla, Chile (Southern Hemisphere). 2ES will be dedicated to a > 5-year observing program with access to the majority (2/3) of the tele-scope time with the goal of discovering temperate terrestrial Earth-mass planets in the habitable zone around the brightest solar-type stars in the sky. In order to achieve the extreme precision needed for 2ES to complete its science objectives, a Laser Frequency Comb (LFC) calibration source is crucial in order to be able to calibrate the spectrograph to achieve the extreme precision of 10 cm/s over many years of operation. The LFC must cover the entire wavelength range of 2ES (370 nm to 870 nm) and have comb lines at appropriate spacing (see requirements) and have extreme stability (see requirements). The LFC must be able to function in a as-tronomical observing environment, be remotely operatable and be also to sustain a significant uptime at the astronomical telescope.

DTU er inde i en kraftig udvikling og søger kontinuerligt efter de rigtige kandidater til de mange spændende udfordringer og opgaver, der skal løses. DTU udbyder derfor en aftale vedrørende annonceringsydelser i forbindelse med rekruttering af medarbejdere nationalt og internationalt. DTU har behov for annoncering i nationale og internationale medier, primært online, på både dansk og engelsk, og DTU Koncern HR vil være en tæt samarbejdspartner i hele forløbet. DTU vil kombineret med en automatisk robot, der scraper til Jobindex og jobnet, varetage ca. 70 % af alle annonceringer via dtu.dk. For de resterende 30 % vil der forventeligt skulle anvendes yderligere annoncering på andre jobsites og udgør forventeligt omkring 370 sager årligt. En sag kan både dække over én annonce placeret i flere forskellige medier og flere stillingsopslag i én annonce, eller en blanding af de to. Af Bilag 1 - Kravspecifikation og Bilag 2 - Priser, fremgår de detaljerede krav til ydelser. DTU forventer at købe for ca. DKK 3.000.000 årligt, men DTU forpligtiger sig ikke ud over sit faktiske behov. Rammeaftalen er altså ikke eksklusiv. Den forventede omsætning på Rammeaftalen er beregnet på baggrund af tidligere forbrug samt forventede forbrug med de forudsætninger, der kendes på udbudstidspunktet. Rammeaftalens forventede værdi udgøre DKK 12.000.000, og Rammeaftalens maximale værdi udgør DKK 14.000.000.

This tender relates to the purchase of a mobile Cleaning In Place (CIP) system and a centralized pH System for the demonstrator-scale acetone production plant, representing the primary outcome of the PYROCO2 project. The PYROCO2 project is a prestigious European Innovation Action type project, funded in 2021 under EU's first round of calls for proposals in support of the European Green Deal. The project has twenty partners from eleven countries, including DTU and process engineering partner Bioprocess Technology SL (BPT, Spain), as well as SINTEF AS (SINTEF, Norway) as the PYROCO2 project coordinator. Any questions regarding the tender might include consultations with other partners than DTU. The main goal of the project is to demonstrate at scale the biotechnological production of acetone by using hydrogen and carbon dioxide gasses as main feedstocks. The main deliverable of the project is the construction and operation of a demonstrator-scale chemical production facility at Herøya Industrial Park, Porsgrunn, Norway, and demonstration of industrial CO2-based acetone production at TRL7 with an annual production capacity of approx. 300 tons.

Med nærværende udbud tilstræber Danmarks Tekniske Universitet (DTU) at supplere den eksisteren-de SKI-aftale vedrørende konferencer, seminarer og møder. Formålet er at sikre en fuldstændig dæk-ning af universitetets behov inden for kategorien samt at opnå fuld overensstemmelse (100% compli-ance) med gældende indkøbsrammer og spend. Det bemærkes, at leverandører, der allerede er omfattet af SKI-aftalen, ikke opfordres til at afgive til-bud i forbindelse med dette udbud. Disse leverandører vil pr. automatik indgå i DTU’s samlede porte-følje og vil kunne byde ind på arrangementer via Meeting Manager-systemet. Den samlede aftaleportefølje med SKI aftaler og aftaler i nærværende udbud forventes at starter op d. 1. april 2026. Samtlige reservationer, forespørgsler og bookinger – uanset om disse initieres under SKI- eller DTU-regi – skal håndteres gennem Meeting Manager. Ved henvendelser uden for systemet er leverandøren forpligtet til at afgive tilbud via Meeting Manager, således at alle transaktioner registreres og doku-menteres i overensstemmelse med DTU’s interne procedurer. DTU’s samlede årlige udgifter til eksterne møder og konferencer i Danmark forventes at overstige 20 mio. DKK ekskl. moms, baseret på historiske omsætningstal for 2024 og 2025. Dette estimat er ikke bindende og kan variere i aftaleperioden. Den maksimale omsætning under aftalen er fastsat til 20% over det forventede spend, hvilket afspejler usikkerhed vedrørende fremtidige prisniveauer og behov.

DTU Sustain is working with environmental forensics and metabolomic investigations to study the fate and occurrence of chemicals and small molecules dispersed into the environment. To be able to make these investigations, DTU wants to procure a low-flow liquid chromatography ultrahigh-resolution mass spectrometry platform, capable of characterizing small molecules with collisional dissociation and laser-based ultraviolet-photodissociation (UVPD) for multi-stage molecular fragmentation (MSn) in liquid chromatography time scale.

DTU is acquiring, from Deutsches Elektronen-Synchrotron DESY, 2D diamond compound refractive lenses to focus the hard X-ray beam at the DanMAC beamline. The lenses must focus the beam to sizes of less than 3 µm (FWHM) in the photon energy range 15-35 keV. The packaging of the lenses must be configured in predefined sets and be very compact to allow easy handling and to fit them in near the sample position. The lens sets must each have a phase corrector (also made from diamond) to correct for aberrations in the lenses. The lens sets must be have alignment features to facilitate easy alignment in the X-ray beam. A pinhole mounted in a similar holder is also included in this procurement. The lenses from DESY are specifically designed to be highly compact as the individual lenses are mounted together in a common holder. Each holder can hold up to 20 lenses within an envelope comparable with just 3 lenses of the conventional design. This compact design is highly advantageous to fit the CRLs in near the sample position. The DESY design is further incorporating a phase corrector plate in diamond. This phase plate is correcting unavoidable aberations from the lenses, and required for the microfocus application at the DanMAX beamline. The lenses from other suppliers cannot be delivered with a phase correction plate.
