Super-FRS Project Highlights
Conceptual Design Report for lateral iron shielding approved
The Conceptual Design Report (CDR) for lateral iron shiedling in target area was approved. The company Walzengießerei Coswig (Germany) will produce iron blocks for about 2,600 tons. The blocks of iron will surround the production target and the downstream magnets and components dumping the radiation outside the target area.
Time-of-Flight detectors: contract signed
The collaboration contract between FAIR and the Ioffe Institute (St. Petersburg, Russia) for the prodcution of twoTime-of-Flight detectors was signed on 26 June 2020. The Ioffe Physical-Technical Institute belongs to the Russian Academy of Sciences and is one of Russia's largest research centers specialized in physics and technology. The ToF detectors are key instruments of in-flight seprators, like the Super-FRS, since fragments are uniquely identified in charge and in mass by using the so-called Bρ-∆E-ToF method.
Shielding flask tender: call for bids closed
The call for bids of the tender for the production of the shielding flask was closed. Seven company applied. Purpose of the shielding flask is the transport of highly radioactive material between the target area and the so-called "hot cell". The flask is equipped by a carrying frame and a winch that pulls it through a shaft of a length of about 8m. The wall thickness of the flask is designed in a way that at surface the maximum dose rate is below 100 µSv/h. The total weight is about 25 t.
Conceptual Design Report for NC dipoles approved
The Conceptual Design Report (CDR) for normal-conducting (NC) radiation-hard dipoles was approved. The dipoles will be produced by the Budker Institute Of Nuclear Physics (BINP) in Novosibirsk (Russia) in the frame of an In-Kind collaboration contract. The NC dipoles are the first triplet of dipoles after the production target. They are subject to a high level of radioactivity therefore they must be remotely adjusted to a sub-millimetre precision.
Contract signed for lateral iron shielding in target area
The tender for the production of the lateral iron shiedling in target area was awarded to the company Walzengießerei Coswig (Germany). The foundry will produce iron blocks for about 2,600 tons. The blocks of iron will surround the production target and the downstream magnets and components dumping the radiation outside the target area.
Specifications approved for the Quench Detection units
The specifications of the Quench Detection Unit (QuD-U) are approved. The QuD-U is the core componentof the Quench Detection System. This will serve to detect and protect superconducting magnets from quenching. The QuD-U is composed of two separate printed circuit boards: the analog board QuD-A which acquires voltages from the superconducting magnets, provide high voltage insulation and quench trigger generation, and the digital board QuD-D which enables data acquisition, remote control of the QuD-A and communication with the control system.
