The EUROTRANS Project

Accelerator Driven Systems (ADS) for nuclear waste transmutation require proton drivers with energies between 600 and 800 MeV and beam currents of several mA for demonstrators and up to 25 mA for large industrial systems. Within the EUROTRANS project a 600 MeV linac has been designed to meet the stringent requirements regarding reliability, availability and extreme low beam losses. The first accelerating section using the novel CH-cavity accelerates the beam to 17 MeV at the injection point into the main linac. The intermediate energy section (17-100 MeV) of the main linac consists of superconducting independently phased spoke-type cavities followed by the high energy section consisting of 704 MHz superconducting elliptical cavities. The paper covers the development of the linac, prototype testing and reliability considerations of the whole EUROTRANS project.

Proton Driver Linac for the Frankfurt Neutron Source

The Frankfurt Neutron Source at the Stern-Gerlach-Zentrum (FRANZ) will deliver high neutron fluxes in the energy range of 1 to 500 keV. The Activation Mode provides a high averaged neutron flux created by a cw proton beam of up to 5 mA, while in the Compressor Mode intense neutron pulses of 1 ns length are formed with a repetition rate of up to 250 kHz. The Compressor Mode is well-suited for energy-dependent neutron capture measurements using the Time-of-Flight method in combination with a 4{pi} BaF{sub 2} detector array. The design of the proton driver linac for both operation modes is presented. This includes the volume type ion source, the ExB chopper located in the low energy section, the RFQ-IH combination for beam acceleration and the bunch compressor. Finally, the neutron production at the lithium-7 target and the resulting energy spectrum is described.
