The first clinical trial with carbon beams generated
from the HIMAC was conducted in
June 1994. The total number of patients
treated is now in excess of 2500 as of De-
cember 2005. Based on our 10 years of experience with the HIMAC, we have proposed a new carbon-ion therapy
facility for widespread use in Japan. The key technologies of the accelerator and irradiation systems for the new facility
have been developed since April 2004. The new carbon-therapy facility will be constructed at Gunma University
from April 2006. As our future plan for the HIMAC, further, a new treatment facility will be constructed at NIRS
from April 2006. The design work has already been initiated and will lead to the further development of the therapy
with the HIMAC. The facility is connected with the HIMAC accelerator complex and has two treatment rooms with
horizontal and a vertical beam-delivery systems and one room with a rotating gantry. We will report the development
for new carbon therapy facility and the design study for new treatment facility with the HIMAC.
Design of a Treatment Control System for a Proton Therapy Facility
The Midwest Proton Radiotherapy Institute
J.E. Katuin, J.C. Collins (IUCF)
(MPRI) is a facility dedicated to cancer treatment
using proton therapy, and is housed
within the Indiana University Cyclotron Facility (IUCF). IUCF has provided MPRI facilities, which include beam
delivery, dose delivery, and patient positioning systems. These systems are implemented using different operating
systems, control software, and hardware platforms. Therefore, IUCF developed an XML protocol for these systems so
that a common treatment control system could issue commands, and receive feedback and statuses over a local area
network (LAN). This protocol was also applied to the MPRI clinical database used to access patient treatment plans.
Consequently, a treatment control system was designed so that a single user interface could be used to deliver proton
therapy. The use of the XML and the LAN allowed the software of the treatment control system to be designed such
that the various systems are treated as objects with properties and methods. This approach not only simplified the
overall design of the treatment control system, it also simplified the effort required for software validation, testing,
and documentation.
Production of MeV Photons by the Laser Compton Scattering Using a Far Infrared Laser at
SPring-8

In order to produce MeV gamma-ray by
the Laser Compton scattering (LCS), a high
power optically pumped Far Infrared (FIR)
laser has been developed at SPring-8. In the
case of the SPring-8 storage ring, the momen-
tum acceptance is so large (± 200 MeV) that the scattered electron is re-accelerated, then the stored beam is not lost
by the LCS process. The beam diagnostics beamline is used to inject a FIR laser beam against 8-GeV stored electron
