C3042001 12 DETECTOR (HPGE) Large volume, closed-end coaxial HPGe Canberra C3042001 13 detector (Model: GC3518). C3042001 14 SAMPLE natCaF2 powder sealed in the back with a small piece C3042001 15 of Cu wire. The dimensions of the target were then C3042001 16 just the internal dimensions of the packed cathode, 1 C3042001 17 mm in diameter and 3.5 mm in length. Using the mass C3042001 18 of the packed CaF2 powder and these internal C3042001 19 dimensions of the cathode, the density for each C3042001 20 packed cathode was calculated, with an overall C3042001 21 average density of around 3.0+-0.2 g/cm3. C3042001 22 ANALYSIS The total yield can then be found by using the C3042001 23 calculated initial activity and the total charge C3042001 24 collected on the cathode material Q, using C3042001 25 Y=lambda*Ao/((Q/t1)*(1-exp(-lambda*t1))), where t1 is C3042001 26 irradiation time, A0 is initial activity, lambda is C3042001 27 isotope's decay const. C3042001 28 ERR-ANALYS (ERR-T) Error bars on the measured data points were C3042001 29 the result of the propagation of uncertainties due to C3042001 30 Poisson statistics in the number of counts in the C3042001 31 peak, uncertainties in the efficiency of the detector, C3042001 32 the given uncertainties of lambda and Igamma from C3042001 33 NNDC, a 5% uncertainty on the collected charge from C3042001 34 the beam current, and uncertainties in the recording C3042001 35 times. C3042001 36 (ERR-1) The collected charge from the beam current. C3042001 37 DECAY-DATA (21-SC-43,3.891HR,DG,372.9,0.225) C3042001 38 (21-SC-44-G,,DG,1157.)
