UC Berkeley Campus

 

This will be the third Summer School in Radiation Detection and Measurements organized with the goal to convey basic and advanced concepts in radiation detection and their broad range of applications.

This year the focus will be on solid-state detectors and associated applications primarily in the detection and identification of gamma rays. In contrast to the previous two years, this year we combine lectures in the morning with experiments in the afternoon. We hope to be able to have the lectures in Donner Hall again as it is one of the historically important places for many developments in radiation detection and applications and provides a surrounding, which stimulates discussions between lecturers and students. The experiments will be performed close by in Etcheverry Hall where the Department of Nuclear Engineering is located.

 

The first part of the lectures will cover semiconductor detectors including requirements for materials, currently of significant interest to realize room-temperature operational, high-resolution detectors, detector implementations, and operations. The ability to track gamma rays, i.e. to measure positions and energies of individual gamma-ray interactions and determining their scattering sequence, will be discussed in the context of nuclear physics and gamma-ray imaging applications. New concepts in the implementation of Ge detectors – Ge drift or so-called point contact detectors - will be introduced and discussed for potential applications in basic and applied research.

 

In the second part we will move on to discuss basic concepts, requirements, and recent advances in scintillations detectors. Applications particularly in imaging of photons and in combination with other modalities such as magnetic resonance imaging will be discussed. At the end, we will have one lecture on digital signal processing which enables very flexible implementations of time-variant filters to optimize the extraction of specific features of interest.

 

As in the years before, we will have time for questions and conversations in between lectures while enjoying coffee or tea and snacks under the trees of the Donner Hall patio.

 

For the afternoon, we are planning experiments, which go along with the focus of this summer school to convey basic and advanced concepts in solid-state based radiation detection. We will perform experiments with simple Ge detectors, pixilated CdZnTe, and double-sided strip detectors in combination with analog and digital data readout. In particular the digital readout will be used to explore digital filtering to determine not only energy and time of the incident radiation but also the positions of interactions. This will be used for gamma-ray tracking and a range of gamma-ray imaging modalities such as pin-hole, coded aperture, and Compton imaging. We are planning to perform coincidence measurements to demonstrate non-linear effects in the response of scintillation detectors, which represents one of the limiting factors in realizing the full potential of such devices.
