Status of Frankfurt Neutron Source FRANZ
نویسندگان
چکیده
To fulfil the requirement on beam luminosity the ion source has to deliver a cold and intense proton beam with a generalized perveance of K = 3.1·10. Therefore, it was decided to use a hot filament driven gas discharge ion source providing very small beam emittances due to the very low plasma temperature. Furthermore, this source type is able to produce high beam intensities. Preliminary experiments using the source prototype exhibit a beam current of I = 245 mA with a proton fraction of 92%.

The Frankfurt Neutron Source at the Stern-gerlach-zentrum (franz)∗
About 40ns long proton pulses with an energy of 120keV and currents of up to 200mA will be produced at the 150kV high current injector with a repetition rate of up to 250kHz. The first part of acceleration will be done by a 175MHz-RFQ. After this section the proton bunches will have an energy of about 1.0MeV . A 5-gap-cavity will allow for an energy increase and for a variable end energy from 1...
