Purpose To establish and investigate the effects of dose, linear energy transfer (LET), and O2 concentration on biologic response to ultrahigh dose rate (uHDR; FLASH) helium ion beams compared with standard dose rate (SDR) irradiation. Methods and Ma

Recently, it has been proposed that a mixed helium/carbon beam could be used for online monitoring in carbon ion beam therapy. Fully stripped, the two ion species exhibit approximately the same mass/charge ratio and hence could potentially be acceler

At particle therapy facilities with pencil beam scanning, the implementation of a ripple filter (RiFi) broadens the Bragg peak, so fewer energy steps from the accelerator are required for a homogeneous dose coverage of the planning target volume (PTV

Freeze-dried cryo-sections of barley roots ( Hordeum vulgare L. cv. Alexis ) were used to investigate the possible role of the root apoplast as an iron-storage pool for plants; this possibility has been a matter of controversy. Micro-PIXE analyzes in

A new software package “BIOPIXE” with emphasis on biological samples inhomogeneous in mass is presented. PIXE and STIM measurements were carried out on pixel-by-pixel basis. The elemental concentrations are evaluated using GUPIX. Main features of

By building up a cryo-preparation laboratory a method was developed which allows us to prepare cryo sections of fully differentiated plant-root material, according to the requirements of the proton microprobe. Since cryo-preparation is the only possi

Geosiphon pyriforme is a unique symbiosis between a fungus, belonging to the arbuscular mycorrhizal (AM) fungi, and a cyanobacteria (blue-green algae). Since more than 80 % of the land plant species form an AM, the importance of this symbiosis become

Geosiphon pyriforme represents the only known endosymbiosis between a fungus, belonging to the arbuscular mycorrhizal (AM) fungi, and cyanobacteria (blue-green algae). Therefore we use Geosiphon as a model system for the widespread AM symbiosis and t

We developed a new technique to determine the impact position of single pencil beams in the image plane with an accuracy of 0.2 μm. This technique bases on the overlapping of secondary electron images from a 1000 mesh grid. The measurements themselv
