All the above values give a tentative picture in order to plan an experiment. The  parameters may be adjusted and evaluated during the beam time. The available beam energy also depends on the machine condition during the run.

Particle Flux :    1-2  x  10⁵ particles/cm² /sec

All the  irradiation jobs are done at the atmospheric pressure. The samples have to be prepared in form of a monolayer. The attaching types of mammalian cells are grown on a 35 mm NUNC Petri-dish. The dishes are irradiated in a horizontal position. Non attaching cells can also be irradiated in the horizontal position using a special method. Irradiation with a pre-determined fluence and subsequent repetitions can be done using a the irradiation system called ASPIRE.
