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.

Transition radiation (TR) is nowadays intensively exploited
by a number of techniques to characterize different beam
parameters. These methods are based, sometimes implicitly,
on standard formulae, and used often without paying
due attention to their applicability. In particular, standard
expressions are only first-order asymptotic, i.e., strictly
speaking, valid at infinity. In this paper TR is examined in a
spatial domain where conventional results are no more exact
and variations in radiation properties are observed. Under
certain conditions, for example, at long wavelengths or
very high energies the effect is so considerable that should
be taken into account in accurate beam measurements.

The APT/LEDA personnel radiation protection system
installation was accomplished using a flexible, modular
proven system which satisfied regulatory orders, project
design criteria, operational modes, and facility
requirements. The goal of providing exclusion and safe
access of personnel to areas where prompt radiation in the
LEDA facility is produced was achieved with the
installation of a DOE-approved Personnel Access Control
System (PACS). To satisfy the facility configuration
design, the PACS, a major component of the overall
radiation safety system, conveniently provided five
independent areas of personnel access control. Because of
its flexibility and adaptability the Los-Alamos Neutron-
Science-Center-(LANSCE)-designed Radiation Security
System (RSS) was efficiently configured to provide the
desired operational modes and satisfy the APT/LEDA
project design criteria. The Backbone Beam Enable
(BBE) system based on the LANSCE RSS provided the
accelerator beam control functions with redundant,
hardwired, tamper-resistant hardware. The installation
was accomplished using modular components.
