The High Voltage RadioFrequency Test Facility (HVRFTF) has been developed with the aim to be a simple, accessible and flexible test facility to characterize the dielectric strength in vacuum of the RF drivers of SPIDER and MITICA ion source and effectively address the issues related to the ir voltage hold off when subjected to their operating radio frequency E - fields and pressure . This report presents the results of the test campaign s carried out in 2017 on stainless steel planar circular electrodes with Argon injection. Currently the HVRFTF is able to supply RF voltage of more than 10 kV, producing E - fields up to 55 MV/m for a gap of 0.2 mm. The experimental activity, besides the collection of data relevant for the main HVRFTF scope, allowed gaining experience and addressing specific issues related to the setu p and operation of the facility.

Abstract
The High Voltage RadioFrequency Test Facility (HVRFTF) has been developed with the aim to be a simple, accessible and flexible test facility to characterize the dielectric strength in vacuum of the RF drivers of SPIDER and MITICA ion source and effectively address the issues related to the ir voltage hold off when subjected to their operating radio frequency E - fields and pressure . This report presents the results of the test campaign s carried out in 2017 on stainless steel planar circular electrodes with Argon injection. Currently the HVRFTF is able to supply RF voltage of more than 10 kV, producing E - fields up to 55 MV/m for a gap of 0.2 mm. The experimental activity, besides the collection of data relevant for the main HVRFTF scope, allowed gaining experience and addressing specific issues related to the setu p and operation of the facility.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
