Titanium, water-cooled vacuum chambers for SFRS

Kurze Beschreibung

The first dipole stage of the super-FRS is situated in the target area and is formed by three 11-degree normal conducting (NC) dipoles. Due to the expected beam losses on the vacuum chamber walls, these dipoles must be able to withstand intense beam pulses. Intense beams scrape against the chamber wall at steep angles. Therefore, the chamber wall should be made of titanium alloy Ti6Al4V (3.7165) and water-cooled. A power of up to 2.4 kW with very localised energy deposition must be expected. In one single pulse energy densities up to 1 kJ/g can be reached. Because of its particular horn shape in the horizontal plane, the chamber's open aperture is defined by a rectangular profile with a constant vertical opening and a varying horizontal opening. The support structure, which holds the chamber in place, is also part of the delivery.

Vacuum interfaces between the vacuum chamber and neighbouring systems are provided via special "pillow seals" that operate at 1.5 to 2 bar above atmospheric pressure. A pillow seal exerts a large pushing force of up to 64.5 kN at the wide end and 39 kN at the narrow end.

Support structure design shall consider the forces exerted on the vacuum chambers by the pillow seals. The chamber and the support structure shall be able to withstand these forces.

There are two types of chambers defined as type 1 long and and type 2 which are differed by their length. Type 1 is 3200 mm long and a horizontal aperture minimum of 1122 mm at the wide end. Type 2 is 3650 mm long and horizontal aperture minimum of 1200 mm at the wide end. Both types has a vertical aperture minimum of 140 mm and 500 mm of horizontal aperture minimum at their narrow end. Contractor shall deliver one type 1 chamber and two type 2 chambers and the associated support structure.

Zusätzliche Informationen

The only form of submission of participation applications accepted by Awarding Authority is in writing, electronically

Note: In Writing, Electronically

Participation applications shall be submitted electronically within the deadline via the German awarding platform DTVP.

URL: http://www.dtvp.de/Center/

The forms and other documents to be completed, provided by FAIR, may be

- either completed on the online tendering tool under the section "Documents to Be Completed" or

- created and compiled separately by Candidate together with the other components of the participation application or tender (concepts or explanations etc.), then uploaded under the heading "Own Documents".

However, Candidates should not fill in the forms online and upload them again separately, as this can result in transmission errors and increases the workload on both sides.

In order to comply with the text form (in writing) according to § 126b BGB [transl.: German Civil Code] when submitting participation applications, Candidates must provide the following information:

- In the case of natural persons, the full name (first name and surname) must be given (name of the declaring person in the participation application form).

- In the case of legal entities and commercial companies and corporations, the name of the company and its legal form must be stated. In addition, the full name of the employee who is submitting the participation application on behalf of the company (name of the declaring person in the participation application form) must be stated. The insertion of a company logo is not sufficient.

- In the case of Bidding Consortia, the declaring person according to § 126b BGB shall be the employee of the leading member who submits the participation application on behalf of the Bidding Consortium; besides, the form "Bidding Consortium Declaration" must be submitted.

It should be noted that in the case of electronic submission, the text form according to § 126b BGB is only observed if the participation applications are transmitted in encrypted form via the awarding platform (cf. information on eVergabe). Submitting the participation application via email is not sufficient.

In the case of incorrect/ incomplete information that violates the aforementioned formal requirements, participation applications will be excluded unless Candidate cannot be held responsible (§ 57 para. 1 nr. 1, para. 3 VgV).
