AGATA (Advanced GAmma Tracking Array) is a new type of spectrometer using gamma ray Tracking. The principle of tracking bases strongly on the high segmentation of these detectors in combination with digital electronics. This allows to obtain online position information for the individual gamma interactions within the germanium shell with a resolution much beyond the physical segmentation...

30. Gamma calorimeters for experimental studies relevant to explosive nucleosynthesis

Sotirios Harissopulos (NCSR "Demokritos" - Athens)

A new method employing a large-volume NaI crystal was developed for cross-section measurements of astrophysically relevant capture reactions on medium-mass nuclei. The response function of such a 4 pi calorimeter enables the summing of all capture events. As a result, a single peak, the so-called sum peak, arises in the spectra. Its intensity can be used to obtain very low cross sections of...

60. FIssion Detector In AStrophysics (FIDIAS)

Michail Axiotis (INP, NCSR "Demokritos")

Time Projection Chambers are widely used since many years for tracking and identification of charged particles in high energy physics. The feasibility of using a low-cost and "mobile" instrument of this kind to count the recoils, instead of the gammas, emitted by a capture reaction in inverse kinematics is investigated. This approach would provide a breakthrough for cross section measurements...

66. Gamma ray spectroscopy studies in Bucharest

Constantin Mihai (IFIN-HH)

A recent commissioned array that combines the excellent energy resolution of 8 HPGe detectors with the timing properties of 8 LaBr(3) scintillators was used in gamma-ray spectroscopy studies at the Bucharest FN tandem. The array's flexibility makes it suitable for lifetime measurements by In-Beam Fast Timing, Doppler Shift Attenuation Method and, in combination with a plunger device by...
