The occasion of the MAC's visit to analyze progress towards Elettra 2.0

01/12

On Wednesday 12 and Thursday 13 February, the annual meeting of the Machine Advisory Committee (MAC) was held at Elettra-Sincrotrone Trieste, a key moment to assess the progress of the facility's activities. As part of the event, the members of the MAC took part in a technical visit focused on the progress related to the creation of Elettra 2.0, the new generation light machine.

Magnet feeding systems and technological innovation
The tour began with the presentation of the power converters developed internally for Elettra 2.0. Two main models were examined:
the model designed for the power supply of multipole magnets and trim coils.
the model intended for slow/fast correctors and ID correction coils.

Both converters, exhibited in the Elettra museum area, were activated to demonstrate their performance characteristics, including:

Quiet operation thanks to air-cooled only.
Wide bandwidth.
High spectral purity of the model intended for fast correctors

To highlight the engineering and maintenance aspects, two other converters were shown in an open configuration. The research and development work has made it possible to optimize the design, ensuring high efficiency and a significant reduction in running costs thanks to the use of 75% of components common between the two models.
A further innovation concerns the control system, which uses an SFP fiber optic interface with a reading and regulation speed of up to 100 kHz. This enables real-time monitoring of key parameters such as currents, voltages, and temperatures, facilitating the implementation of predictive strategies for fault management.

Serial construction, in the large quantities necessary for the project, is underway and makes use of industrial partners.

Magnets for Elettra 2.0: logistics and advanced measures
A particularly significant moment of the visit concerned the access to the building intended to house the magnetic measurement laboratory and the storage of the magnets, which will constitute the new accelerator, before their installation. Currently, the facility is home to the first 130 magnets, part of a total of six shipments planned by Danfysik, the company selected to supply the quadrupol magnets and other multipolar, sextupole and octupole magnets.

Inside the building, a delimited and thermostated area has been created in which the new laboratory for the characterization of magnets has been set up, equipped with advanced measurement systems:

Rotating coils for the analysis of quadrupoles, sextules and octupoles.
Stretched wire for aligning a string of multi-pole magnets on the respective girder, ensuring the correspondence between the axis of symmetry of the magnetic field and the beam trajectory.

3D mapping of the magnetic field in dipoles using Hall effect sensors.
The entire measurement system and magnetic components have been designed and assembled by Elettra, combining elements available on the market with components made to specification by specialized companies.
The members of the MAC were able to take a close look at the measuring benches and the preliminary set-up of the girders, granite structures designed to accommodate groups of three to six magnets depending on their position in the achromat of the accumulation ring.

Insertion devices for Elettra 2.0
The visit ended in the Insertion Devices laboratory, where the tools used for magnetic measurements and the progress of the creation of short IDs for Elettra 2.0 were illustrated.

The meeting was an important opportunity to share with the MAC the technological and infrastructural advances underway, highlighting the developments towards the completion of the new generation of the light machine.
