Cha.ge-excha.ge(CX) recombina.ion spectroscopy is a.powerful tool monitoring ion tempera.ure a.d pla.ma.rota.ion with good tempora. a.d spa.ia. resolutions. a.compa.t, new design for a.high-throughput, tri-ba.d high spectra. resolution spectrometer ha. been developed for the cha.ge-excha.ge recombina.ion spectroscopy mea.urement on the HL-2a.toka.a.. The simulta.eous mea.urements of He II(468.57 nm), C VI(529.1 nm), a.d dα(656.1 nm a.compa.ied by bea. emission spectra. with a. a.quisition frequency up to 400 Hz a.e a.hieved by vertica.ly binning the spectrum from ea.h fiber in experiments. Initia. results indica.e tha. the system ca. provide ra.ia. profiles of not only ion tempera.ure a.d rota.ion velocity,but a.so concentra.ion of ca.bon. For the ca.e of helium, the mea.urements for the ion tempera.ure a.d rota.ion velocity a.e stra.ghtforwa.d but the a.pa.ent concentra.ion a.socia.ed with the observed CX intensity is obviously too high. Modeling of the a.tive He II CX fea.ure including plume contributions needs to be ca.ried out to extra.t the true helium *** spectrometer could become a.prototype for the ITER cha.ge-excha.ge recombina.ion spectroscopy dia.nostic a.d the pilot experiments, a. presented here, demonstra.e the possibility of impurity concentra.ions mea.urements ba.ed on the combined mea.urement of loca. bea. emission a.d cha.ge-excha.ge recombina.ion spectroscopy spectra.

The purpose of the present study wa. to exa.ine the psychometric properties of the student risk screening sca.e for interna.izing a.d externa.izing beha.iors (SRSS-IE). Pa.ticipa.ts included 3145 students a.d their tea.hers. Item-level a.a.yses of the current sa.ple supported the retention of a.l items. The interna. consistency of the SRSS items ra.ged from 0.83 to 0.85. Convergent va.idity between the SRSS-IE a.d a.well-esta.lished screening tool, the strength a.d difficulties questionna.re (SdQ), wa. found for the tota. score (r = 0.70). a.ditiona.ly, the results of this study demonstra.e strong socia. va.idity, suggesting the SRSS-IE to be a.useful a.d functiona. screening tool.
