Light Ion Facility (LIF)

CRC

Available energies @ LIF

Different available energies have been calculated using SRIM code taking the different beam line items into account (beam diffusion foil, pressure window, air and transmission chamber).

With a combination of 5 blocs, 17 different energies are possible at the DUT position (see table below):

For the 10MeV beam (produced with 5 degradors from a 65MeV primary beam), the FWHM is 5 MeV.

Flux

For beam flux, the health physics department sets the maximal limit to 2E8 part/s.cm².

Lower beam flux can be reached, down to a few thousand part/s.cm².

Higher beam flux can also be available on special request.

Homogeneity

A +/- 10% homogeneity has been measured over 80mm in the horizontal direction and over 80mm in the vertical direction
