This paper describes the latest developments in the Worcester Polytechnic Institute (WPI) Precision Personnel Locator (PPL) project. The RF -based PPL system is being developed for tracking of first responders and other personnel in indoor environments. The system
The RF design of the LINAC4 RFQ
free download
In the Linac 4 and the SPL, a 3 MeV RFQ is required to accelerate the H-beam from the ion source to the DTL input energy. While the 6-meter long IPHI RFQ was initially chosen for this application, a CERN study suggested that a dedicated, shorter 3-meter RFQ might
RF Design of the IFMIF-EVEDA RFQ
free download
Abstract The RFQ of IFMIF-EVEDA project is characterized by very challenging specifications, with 125 mA of deuteron current accelerated up to 5 MeV. Upon beam dynamics studies, it has been chosen a law for the variation of R0 and voltage along the
