Vacuum Furnace @ Frascati

Vacuum Furnace (Laboratori Nazionali di Frascati, Rome)

Furnace for vacuum brazing of components for particle accelerators.

Technical means

The platform is equipped with a vacuum furnace for vertical brazing. The heating resistors are in molybdenum while pumping is performed by a turbomulecular pump. The available space for brazing is 800 mm (height) and 400 mm (diameter). Temperature up to 1000 degree can be reached.

Achievements, related projects

In the furnace the following particle accelerators devices have been recently brazed: RF deflectors for SPARC, PSI and FERMI@Elettra and C band structures for the SPARC_LAB Energy upgrade.

Technical steps, expertise

Construction/cleaning of the parts to be brazed according to the standard requirements of the LNF Vacuum Group. Assembly of components and insertion in the furnace. Brazing cycle. Vacuum test of brazed components with He leak detector.
