BIOMAT Collaboration: High-Energy Irradiation Facility for Biophysics and Materials Research
The FAIR accelerator complex at GSI will be a unique facility, where heavy ions with energies up to 10 AGeV can be used for radiobiology and materials research. The BIOMAT proposal presents the technical design of the BIOMAT irradiation facility at the high-energy beam line of FAIR, which is dedicated
(a) to biophysical experiments and
(b) to experiments for ion-induced changes in solids
.
The BIOMAT laboratory will be located in the High-Energy Cave (Fig. 1), which is shared with the SPARC Collaboration.

A key issue for the planned BIOMAT facility is setting up flexible target stations and providing access to a wide range of different beam parameters (such as kinetic energies, ion charge states etc). The High-Energy Cave has thus to be connected to both the SIS18 and the SIS100 synchrotron. To allow high-quality irradiations of larger sample areas, a magnetic beam scanner will be installed. Additionally, a passive scattering system will be provided. The main target station will comprise various flexible set-ups such as a remote-controlled moving belt for positioning of smaller samples and larger devices (e.g. detectors, space devices) together with a robotic system for automatic handling of biological samples. Irradiation experiments on samples exposed to extreme pressure conditions will be performed in a high-pressure device equipped with a large-volume multi-anvil cell. Finally, for basic studies allowing in-situ und on-line monitoring of ion-induced processes, a multi-purpose UHV-chamber is planned. An additional target set-up in close vicinity of the beam dump will allow experiments with extreme beam conditions with respect to fluence and beam energy. |
