The Superconducting FRagment Separator (Super-FRS) will be the most powerful in-flight separator in the world. Rare isotopes of all elements up to uranium will be produced at relativistic energies and spatially separated within a few hundred nanoseconds, enabling the study of very short-lived nuclei. The Super-FRS is the central device of the NUSTAR collaboration.
The Super-FRS is constructed in the frame of the FAIR international project. Scientists, engineers, and technicians of several countries are working together to carry out the construction of the machine. The core team is working on GSI-FAIR campus.
The realization of the Super-FRS machine is a sub-project of the FAIR international project. The sub-project Super-FRS has a defined scope (established by means of the Work Breakdown Structure), within defined time-planning and costs. Seven shareholder countries and several international companies are involved in the sub-project.
To give you a flavour of what the machine is going to be, here you can find photos, designs, and videos of the Super-FRS components. Get your own impression of the forefront technology behind the superconducting fragment separator.
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.
