Invited talk

The gamma-ray energy tracking array GRETINA uses 28 Ge crystals, each with 36 segments, to cover ¼ of the 4pi solid angle. The gamma ray tracking technique requires detailed digital pulse shape information from each of the segments. These pulses are analyzed to determine the energy, time, and three-dimensional positions of all gamma-ray interactions. This information is then utilized, together...

Invited talk

A novel, large volume, HPGe detector concept capable of providing high efficiency, excellent energy resolution, and extremely fine position sensitivity will be described. The device, referred to as an "Inverted Coaxial" HPGe detector, is based on a non-standard closed-end coaxial geometry and employs point contact technology [1,2]. Experimental characterization measurements have been made...

70. Digital pulse shape analysis method to extract interaction position for CNS-GRAPE

Contribution talk

We are developing a method to extract gamma-ray interaction positions in the segmented planar Ge detector of CNS-GRAPE. The total array of CNS-GRAPE consists of 18 detectors and each of which contains two Ge planer crystals with the effective radius of 30mm and the thickness of 20mm. The cathode of each detector is divided to 3×3, and the anode is common. The pulse shape data from each...
