Sample geometry considerations are important for quantitative analysis. Whilethe sample should be positioned at a location with maximum beam fluence,reproducibility of the sample position is also highly desired. During this phase of theproject, the neutron radiography camera malfunctioned and the determination of thebeam profile at this position using neutron radiography technique widely reported inliterature could not be achieved. In its absence, the beam profile at the sample position 43was determined by comparing the peak area counts during irradiation of Cd foils atdifferent marked positions in the sample chamber as shown in Table 3-1.
