On November 14th and 15th, 2023, the Low Emittance Ring – Permanent Magnets Workshop (LER-PerMag) was held at the Savoia Excelsior Palace in Trieste.
Kyma collaborated with Elettra Sincrotrone Trieste and ALBA Synchrotron in organizing the workshop, sponsored by I.FAST and LEAPS-PerMaLIC.

At the workshop, which also saw participation from companies ZHmag and VacuumSchmelz, the primary objective was to encourage collaboration and knowledge exchange among experts in this field. The focus was on sharing design challenges and experiences among institutes, research centers, and companies. A total of 42 participants attended from Europe, the USA, and Asia.

New Low Emittance Rings are nowadays increasingly considering the use Permanent Magnets in their designs thanks to two main advantages: it allows a more compact distribution of magnets, since there is no need of coils and water cooling, obtaining, as a by-product, a much higher beam stability of the beam; and on the other side, it allows to reduce the running costs and the carbon footprint of the facility because of the removal of the power supplies associated to conventional electromagnets. However, the use of Permanent Magnets also presents some serious challenges such as the loss of flexibility for the correction of errors, correction that it is needed to ensure the proper beam dynamics performance and stability, and the long-term stability of the magnets themselves due to the risk of radiation-induced demagnetization.

The event ended with the visit to Kyma and Elettra.
