Welcome to "Table-Top Proton Synchrotron (TTPS)"
at KEK
High Energy Accelerator Research Organization
We are developing a compact table-top proton synchrotron and a very small
Carbon ion Synchrotron for Radiotherapy under contract with NIRS
(National Institute of Radiological Science) and other institutes with
the grant of the Ministry of Education and Science. We have succeeded
in developing High Field 3-T Dipole Magnet with the bending radius of
0.72m which is suitable for this purpose. Further developments of various
devices are underway.
World highest record of RF acc. gradient of 60 kV/m by the 0.4m metallic
alloy core cavity with 2 gaps in June 22, 2004.
