WebMay 1, 2024 · RF conditioning of the RFQ linac. The RF conditioning of the RFQ cavity aims at achieving 600 kW in CW stored in the cavity, which corresponds approximately to the required electric field to accelerate deuteron beam. The water and gases remaining adsorbed on the cavity surface can be eliminated through the high power RF conditioning. WebCERN

A H 2 + ion beam extracted from an electron cyclotron resonance (ECR) ion source was used for the beam commissioning because deuteron beam acceleration will produce a serious radiation risk. We compared and analyzed the measurement results obtained during the beam ... cvo workflow

WebThe SPIRAL2 88 MHz CW RFQ is designed to accelerate light and heavy ions with A/Q from 1 to 3 at 0.73 MeV/A. The nominal beam intensities are up to 5 mA CW for both proton and deuteron beams and up to 1 mA CW for heavier ions. The design foresees almost 100% transmission for all ions at nominal beam current and emittance. Beam commissioning … Webx the RFQ transmission specified over 97% (100% from design) since deuteron beam losses would seriously complicate the maintenance in the linac tunnel. Finally this point is not so critical, as the RFQ output energy is low (0.75MeV/u), nevertheless the design cannot be changed and lead to a very precise vanes machining (less than 40µm), cheapest flights from az to nc
