The MONOLITH H2020 ERC project aims at the development of fully monolithic highly granular pixel sensors with pico-second time-stamping capabilities. Using high-resistivity epitaxial layer material in combination with a continuous deep and thin gain layer, a pico-second fast detector response is achieved over the full pixel cell. The placement of the gain layer away from the pixel junctions...
In the last decades, the number of Proton Therapy centers has increased substantially in Asia, in the US and lately in Europe. The characteristics of the Bragg-peak allows precise longitudinal confinement of the prescribed dose to the tumor. Laterally, this is achieved by using narrow pencil beams to scan the tumor volume. This however requires precise control of the position in the plane...
Multileaf collimators (MLC) are an integral component in modern radiotherapy as they dynamically shape the MV photon treatment field and therefore need to be closely monitored to ensure correct treatment delivery. Currently, MLC leaves are calibrated to ±1 mm every 3 months, however leaves can drift beyond this during calibration dates and treatment verification only occurs post-treatment....
Purpose. Two prototypes for beam monitoring in particle therapy are being developed based on LGAD technology, aiming at improving and enriching the performances of state-of-the-art gas detectors. The results of tests on clinical proton beams are presented.
Methods. A proton counter for online fluence beam monitoring is made of sensors featuring 3.0x0.5 $cm^2$, 30 strips (150...
