Particle Therapy 2017

Acceleration in synchrotron

magnets

Acceleration Voltage at RF frequency f

V

At electrode slit crossing: Energy gain ΔE= V.q

Energy increases:

 speed ↑  RF frequency ↑  field in magnets ↑

p =

= constant ! r

Bq

Magnets and RF frequency change Synchronous to particle revolution frequency
