“…The resolution in the companion 3x2 EJ315 detector is expected to be similiar [8]. The intrinsic resolution for the EJ301D detector due to the light collection and PMT was then estimated using a fast, pulsed, stable (<1% variation in light output) blue LED light source [24] inserted via a fiber optic (FO) cable to the SMA FO fitting at the detector cell-PMT interface (Fig.1) to simulate a detector scintillation signal. A typical LED pulser spectrum in the 3x3 EJ301D detector, with the LED intensity matched to a similar Compton electron signal, is shown in Fig.8.…”

In conjunction with Eljen Technology, Inc. (Sweetwater,TX) we have designed, constructed, and evaluated a 3 in. x 3 in. deuteratedxylene organic liquid scintillator (C 8 D 10 ; EJ301D) as a fast neutron detector. Similar to deuterated benzene (C 6 D 6 ; NE230, BC537, and EJ315) this scintillator can provide good pulse-shape discrimination between neutrons and gamma rays, has good timing characteristics, and can provide a light spectrum with peaks corresponding to discrete neutron energy groups up to ca. 20 MeV. Unlike benzene-based detectors, deuterated xylene is less volatile, less toxic, is not known to be carcinogenic, has a higher flashpoint, and hence is much safer for many applications. In addition EJ301D can provide slightly more light output and better PSD than deuterated-benzene scintillators. We show that, as with deuterated-benzene scintillators, the

There is increasing necessity for low background active materials as ton-scale, rare-event and cryogenic detectors are developed. Poly(ethylene-2,6-naphthalate) (PEN) has been considered for these applications because of its robust structural characteristics, and its scintillation light in the blue wavelength region. Radioluminescent properties of PEN have been measured to aid in the evaluation of this material. In this article we present a measurement of PEN's quenching factor using three different neutron sources; neutrons emitted from spontaneous fission in 252 Cf , neutrons generated from a DD generator, and neutrons emitted from the 13 C(α,n) 16 O and the 7 Li(p,n) 7 Be nuclear reactions. The fission source used timeof-flight to determine the neutron energy, and the neutron energy from the nuclear reactions was defined using thin targets and reaction kinematics. The Birk's factor and scintillation efficiency were found to be kB = 0.12 ± 0.01 mm MeV −1 and S = 1.31 ± 0.09 MeV ee MeV −1 from a simultaneous analysis of the data obtained from the three different sources. With these parameters, it is possible to evaluate PEN as a viable material for large-scale, low background physics experiments.

“…However, for previous QF measurements, a 60 keV deuteron energy was utilized to address higher trigger rates caused by higher neutron and x-ray fluxes at higher deuteron energy. Given the reported near independence of neutron energy from the deuteron energy at the 90 • angle [35,36], the assumption was made that the neutron beam energy remains at 2.43 ± 0.03 MeV even when the deuteron energy is reduced to 60 keV. Nevertheless, due to the volume of the deuteron plate and the NaI(Tl) crystal, there could be a certain angle distribution slightly different from 90 • .…”

The purpose of this study is to investigate the knowledge and attitude on tuberculosis for the nursing students in Daejeon, South Korea and Yanbien, China. A descriptive study was conducted. Data were collected from April to July of 2015 in each college and a total of 175 students assigned to 107 in Daejeon and 68 in Yanbien participated in the study. The data were analyzed by using the SPSS 21.0. There was no significant difference in knowledge and attitude on tuberculosis between the two groups. According to the results, in both groups, the mean score of knowledge and attitude was very low. In both groups, the correlation among knowledge, attitude and educational experience about tuberculosis was positive. In Daejeon nursing students, the attitude and gender explained about 15.3% and in Yanbien students, the attitude, grade explained about 40.2% in knowledge on tuberculosis. In Daejeon nursing students, the knowledge, health interest and educational experience explained about 23.5% and in Yanbien students, the knowledge and health interest explained about 23.9% in attitude on tuberculosis. Based on these findings, education which can guide nursing students to have correct information and positive attitude should be designed to manage tuberculosis infection. Therefore, it would be utilized in tuberculosis management education effectively for them.■ keyword :|Tuberculosis|Nursing|Student|Knowledge|Attitude|
