Linear accelerator

DTU Nutech operates a non-clinical medical linear accelerator.

The Varian Truebeam is a state-of-the are medical linear accelerator. At Danish hospitals, similar accelerators are used for treatment of cancer patients (external beam radiotherapy). The Truebeam at DTU Nutech is only for non-clinical work (i.e. no patients are treated here). We mainly use the accelerator for dosimetry research.


Model: Truebeam from Varian Medical Systems.

Version: 2.0

Photon energies with flattening filter: 4, 6, 10, 15, and 18 MV

Photon energies without flattening filter (FFF): 6 and 10 MV

Electron energies: 6, 9, 12, 15, 16, 18, and 20 MeV

MLC: Millennium 120 leaf MLC (40 center pairs of 5 mm width, and 20 peripheral pairs of 10 mm width).
