Characterization Studies of Cyclotron CS-30 Carbon Puller Material Using Powder X-Ray Diffraction and SEM, EDX Cross Section Method

The carbon puller material of Cyclotron CS-30 has been characterized to investigate the structure and composition of the puller. Two samples of pullers have been prepared in the form of powder from locally made carbon and the original cyclotron puller. X-ray diffraction (XRD) analysis of both samples powder gives identification of the structure and phase type of carbon, meanwhile the morphology and the elemental composition of both samples can be shown by Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDX) technique. XRD samples are prepared by grinding the puller surface meanwhile the samples for SEM analysis are prepared by cross section method. XRD result shows amorphous carbon structure and a typical broad XRD profile's peaks and the diffused nature of the XRD profile indicate the presence of disorder in the samples. The first peak of the profile corresponds to the (002) peak of the hexagonal graphite structure, while the second peak corresponds to the (100) and (101) for both samples. Results of SEM-EDX showed that the carbon material from the original default puller of the CS-30 cyclotron contains mass percentage of lead significantly by 9.15%.
