SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 2 lutego (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„Image-guided FLASH Proton Therapy”

Referuje: Karol Lang, University of Texas at Austin

Image-guidance and dosimetry of the in-vivo proton range verification is one of the most underinvested aspects of radiation cancer treatment. The scarcity of sensitive instruments and treatment protocols for precision monitoring of effects of beam radiation leaves much room for improvement. This is despite that such measurements may dramatically enhance the treatment accuracy and lower the post-exposure toxicity, improving the entire outcome of cancer therapy.

In this talk, we will discuss designing and building of an in-beam time-of-flight positron-emission-tomography (PET) scanner to be tested in pre-clinical studies at Proton Therapy Center of MD Anderson Cancer Center in Houston. We will also discuss selected results of recent experiments with FLASH proton beam irradiations of phantoms and other related ideas towards improving and expanding the use of PET detectors, including the total body imaging. This endeavor has been made possible by the support of the U. of Texas – Portugal program at the University of Texas at Austin.

SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 26 stycznia (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„Light-by-light scattering and dilepton production in ultra-peripheral heavy-ion collisions with ATLAS”

Referuje: dr Krzysztof Cieśla (AGH)

The presence of a large flux of photons accompanying relativistic heavy ion beams leads to a significant number of photon-induced processes, including photon-photon fusion. These processes are remarkably clean with little or no remnant activity from the interacting particles. I will present the status of photon-photon fusion measurements resulting in either two photons (γγ→γγ) or two charged leptons (γγ→l+l−) in the final state, measured by the ATLAS experiment in ultra-peripheral heavy-ion collisions.

Dnia 19 stycznia (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„Status of the Dose-3D Project”

Referuje: prof. Tomasz Szumlak (AGH)

The dose-3D project aims to provide a next-generation active phantom for rapid measurement of the deposited dose in photon therapy. During the initial development period, a dedicated, modular, and flexible DAQ system was designed and constructed along with a number of prototypes.

The design of the detector configurable matrix was especially challenging. An extensive search for the best scintillating active material and suitable mechanical part provided the required robust support and sufficiently small material budget. We decided to use 3D printing technology for the final prototypes to produce both the scintillating voxels and mechanical parts. Also, considerable effort was dedicated to designing and implementing an interface between the optical fibre and the scintillating voxel. In this talk, I will give the current status of the project and prospects for future developments and commercialisation prospects.
