Procurement of a High-precision single-crystal diffractometer for the SINCRYS micro-focus material-science beamline

Aarhus Universitet

The Department of Chemistry at Aarhus University puts out to tender the purchase of the end-station components to establish the SINCRYS side-station at MAX IV Laboratory in Lund, Sweden. The side-station will be constructed at the existing DanMAX beamline that is located at the fourth sector of the 3.0 GeV ring at the MAX IV Laboratory. SINCRYS will be tailored to high-throughput small unit-cell crystallography, commonly used in or-ganic molecular crystals, inorganic materials, and hybrid organic-inorganic compounds. The energy range will be between 20.30 – 23.00 keV. The instrument aims to maximise flux in a 5 × 5 μm2 (full-width half-maximum, FWHM) beam at the sample position with a defocusing option up to 100 × 100 μm2 using an all-diamond lens transfocator. This facilitates a state-of-the-art instrument to study crystals in the range of 2 - 10 μm (or larger). SINCRYS will be situated in an already existing hutch between a shared optics hutch and the DanMAX experimental hutch. The inner dimensions of the hutch are 5.4 m by 2.7 m, however, the existing beam guide for DanMAX limits the inboard side’s accessibility. The downstream half (ap-proximately) of the experimental hutch is supposed to remain vacant to provide room for future in-strument updates. The tentative end-station layout is presented in Figure 1. Shown are the five major components, diffractometer, beam conditioning unit, detector positioning robot, sample changer robot, and support table. A compact diffractometer with 3-axis (Omega, Kappa & Phi) is necessary to thoroughly sample re-ciprocal space for small unit-cell systems while still allowing a short sample-to-detector distance. The beam characteristics of SINCRYS require a highly precise goniometer with a sphere-of-confusion of less than 200 nm (scanning axis Omega with remaining axes mounted and positioned). All axes need to be encoded as typical data collections require different scan combinations of Ome-ga, Kappa and Phi that must be processed altogether. A fast maximum rotation speed of the scan ax-is (Omega) is advantageous to allow for high-throughput data collections. Regarding the high-throughput operation principle, automatic sample changing, loading, centring, and data collection are prerequisite. Various detector positions will be required to make room not only for standard structure determina-tions but also allow for more sophisticated experiments. The detector, an EIGER2 X 4M CdTe (~15 kg), shall be mounted on a 6-axis robotic arm. The robot must be able to position the detector pre-cisely and accurately while carrying all peripherals (e.g. cooling-water tubes, mounting device) and auxiliaries (e.g. sensitive skin panels) necessary to mount and adequately protect the system. The sample changing robot shall be compatible with standard magnetic sample holder bases and shall be loaded from standardised pucks. No cooling of the pucks (e.g. liquid Nitrogen baths) is re-quired. The two robots will be working in proximity and with overlapping working areas making safety and collision measures essential. The control of all individual components (e.g. detector robot, diffractometer axes) must integrate in-to the MAX IV Tango/Sardana system, allow for individual motor positioning (detector robot, diffractometer axes & tools, sample changer) and automatic data acquisition.

Beskrivelse af udelukkelsesgrunde:
Is the economic operator bankrupt? This information needs not be given if exclusion of economic operators in this case has been made mandatory under the applicable national law without any possibility of derogation where the economic operator is nevertheless able to perform the contract.
Vis mere
Has the economic operator itself or any person who is a member of its administrative, management or supervisory body or has powers of representation, decision or control therein been the subject of a conviction by final judgment for
corruption, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? As defined in Article 3 of the Convention on the fight against corruption involving officials of the European Communities or officials of Member States of the European Union, OJ C 195, 25.6.1997, p. 1, and in Article 2(1) of Council Framework Decision 2003/568/JHA of 22 July 2003 on combating corruption in the private sector (OJ L 192, 31.7.2003, p. 54). This exclusion ground also includes corruption as defined in the national law of the contracting authority (contracting entity) or the economic operator.
participation in a criminal organisation, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? As defined in Article 2 of Council Framework Decision 2008/841/JHA of 24 October 2008 on the fight against organised crime (OJ L 300, 11.11.2008, p. 42).
money laundering or terrorist financing, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? As defined in Article 1 of Directive 2005/60/EC of the European Parliament and of the Council of 26 October 2005 on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing (OJ L 309, 25.11.2005, p. 15).
fraud, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? Within the meaning of Article 1 of the Convention on the protection of the European Communities' financial interests (OJ C 316, 27.11.1995, p. 48).
child labour and other forms of trafficking in human beings, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? As defined in Article 2 of Directive 2011/36/EU of the European Parliament and of the Council of 5 April 2011 on preventing and combating trafficking in human beings and protecting its victims, and replacing Council Framework Decision 2002/629/JHA (OJ L 101, 15.4.2011, p. 1).
Can the economic operator confirm that: a) It has been guilty of serious misrepresentation in supplying the information required for the verification of the absence of grounds for exclusion or the fulfilment of the selection criteria, b) It has withheld such information, c) It has not been able, without delay, to submit the supporting documents required by a contracting authority or contracting entity, and d) It has undertaken to unduly influence the decision making process of the contracting authority or contracting entity, to obtain confidential information that may confer upon it undue advantages in the procurement procedure or to negligently provide misleading information that may have a material influence on decisions concerning exclusion, selection or award?
Vis mere
Is the economic operator aware of any conflict of interest, as indicated in national law, the relevant notice or the procurement documents due to its participation in the procurement procedure?
Has the economic operator or an undertaking related to it advised the contracting authority or contracting entity or otherwise been involved in the preparation of the procurement procedure?

social security contributions, both in the country in which it is established and in Member State of the contracting authority or contracting entity if other than the country of establishment?
of taxes, both in the country in which it is established and in Member State of the contracting authority or contracting entity if other than the country of establishment?
Has the economic operator itself or any person who is a member of its administrative, management or supervisory body or has powers of representation, decision or control therein been the subject of a conviction by final judgment for terrorist offences or offences linked to terrorist activities, by a conviction rendered at the most five years ago or in which an exclusion period set out directly in the conviction continues to be applicable? As defined in Articles 1 and 3 of Council Framework Decision of 13 June 2002 on combating terrorism (OJ L 164, 22.6.2002, p. 3).
