“…The systematic error on m e t e related to ballistic deficit effects was estimated by subsequently removing the lowest voltage from the fit and resulted in 10% for DET5 and 5% for DET2, respectively. Note, a more accurate method to determine m e t e that requires the measurement of the depth-of-interaction is described in He et al [14].…”

This paper presents the spectroscopic performance of two newly developed pixelated HgI 2 detectors. These detectors are 1 × 1 × 0.814 cm 3 and 1 × 1 × 1.016 cm 3 in size. Each detector has four closely packed 1 × mm 2 anode pixels at the center of one of the 1 × 1 cm 2 surfaces. These anode pixels are surrounded by a large anode. All results presented here are based on events from a sub-volume underneath the anode pixels. In these detectors, signals were read out by a discrete electronics based on multiple A-250 pre-amplifiers and a digital oscilloscope for sampling pulse waveforms. Depth sensing technique was used to correct the depth-dependent variation in photopeak amplitude. Main results presented are: (1) energy resolutions of 0.85 ~ 1.3% have been achieved on these detectors; (2) the electron mobility-lifetime product was measured to be ~1 × 10 −2 cm 2 /V and the measured electron lifetime was ~200 μs and (3) variation in electron drifting properties under different anode pixels were observed. Significant non-uniformity in internal electric field strength was also experimentally demonstrated.

“…The measurement of electron mobility of the material will give the researcher some basic information and idea on the penetrations of the electron via material [32][33][34]. The higher value of the electron mobility indicates that the material absorb the electron less than small value of electron mobility.…”

Abstract-The fabrication of single square patch antenna for proposed Leucaena Leucocephala ("Petai Belalang") Wood Plastic Composite (WPC) substrate board (PB Substrate board) and FR4 substrate board is presented in this paper. The experiment objective is to measure the performance of an antenna fabricated on the FR4 and PB substrate (proposed substrate) by comparing the performance in terms of material's dielectric constant and electron mobility and antennas' loss tangent, return loss (S 11 ), radiation pattern and practical antenna transmitting performance. The new substrate compositions of Leucaena Leucocephala stem and polypropylene (PP) are 30% and 70% consecutively. The result for 150 µm (sample B) indicates stability on most dielectric constant (ε r = 3.02), loss tangent (tan δ = 0.029) and electron mobility (5.31 × 10 3 cm 2 /V s ), with the consistency of antenna result, between simulation and measurement. All results obtained will be analyzed and displayed in the form of data and graphs.
