During the last four years GSI has developed a new
procedure for cancer treatment by means of the intensity
controlled rasterscan-method. This method includes
active variations of beam parameters during the treatment
session and the integration of 'on-line' PET monitoring.
Starting in 1997 several patients have been successfully
treated within this GSI experimental cancer treatment
program; within this program about 350 patients shall be
treated in the next 5 years. The developments and
experiences of this program accompanied by intensive
discussions with the medical community led to a proposal
for a hospital based light ion accelerator facility for the
clinic in Heidelberg. An essential part for patients
treatments is the measurement of the beam properties
within acceptance and constancy tests and especially for
the rasterscan method during the treatment sessions.
The presented description of the accelerator controls and
beam diagnostic devices mainly covers the requests for
the active scanning method, which are partly more crucial
than for the passive scattering methods.
