Abstract

Background and Aims

Commercially available real time response dosimetric systems were shown to be unsuitable for Flash therapy, in which ultra-high Dose Per Pulse (DPP) is of interest. There is a need for novel, reliable and fast response detectors for such an application. In the present work, a comprehensive investigation is reported on the properties of diamond-based detectors specifically designed for Flash therapy.

Methods

Several diamond Schottky diode prototypes were produced at Rome Tor Vergata University, in cooperation with PTW Freiburg. Quite a few relevant design and electronical parameters were systematically varied, tuning the device’s overall performance and meet the stringent requirements of ultra-high DPP irradiation. The resulting prototypes were tested by using an ElectronFllsh linac (SIT S.P.A.), by using a 9 MeV electron beam and DPPs up to 12.5 Gy/pulse.

Results

The performance of the prototypes, investigated under a wide range of irradiation parameters, was found to depend on their specific structural properties and designs, showing a response linearity up to a DPP of 12.5 Gy/pulse in the best case.

Conclusions

First results of this systematic investigation, clearly demonstrate the feasibility of a diamond based detector for Flash therapy applications. The analysis of the obtained experimental results will be used as an input for further development and optimization procedure of the investigated prototypes.

The present work is part of the 18HLT04 UHDpulse project which has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
