Traveling wave linacs

Other types of indirect accelerators are vhf resonant cavities and linear induction accelerators, such as travelling wave linacs, standing wave linacs, resonant cavity accelerators and linear induction accelerators [1]. 

With respect to MS, progress in collision cells, e.g., LINAC cell and travelling-wave ion tuimels (Ch. 11.3.5), has enabled shorter dwell times in SRM without response losses. Enhanced-resolution triple quadrupole and Q-LIT instruments show promising results, but have not yet been as widely applied in routine bioanalytical LC-MS. 

At the Institute for the Organic Synthesis and Photoreactivity (ISOF) is operating a 12 MeV (maximum energy with no load) Vickers L-band (1.3 GHz) traveling wave electron linear accelerator. The LINAC was put in operation mainly to be used as energy source for pulse radiolysis studies. 

Radio-frequency linear accelerators (rf linacs) A linear accelerator that employs radio frequency (rf) cavities for electron acceleration. The particles are accelerated in cylindrical cavities that reqitire a high power soitrce for the rf fields. The rf fields in these cavities may be either traveling or standing waves. In the case of traveling wave conflguratiorts, which are most often employed for electron accelerators, the phase velocity if the rf fields must be synchronized with the desired electron velocity.
