The present analysis concentrates on the utilization of low-energy proton accelerators of several hundred kilovolts for particle-induced X-ray emission microanalysis. Experiments on stainless-steel and carbon matrices for thick target conditions have been carried out at several proton energies. The ionization cross sections for some elements are calculated using the ECPSSR theory. The effective cross section and minimum detection limits are calculated for the two matrices. With the availability of ultra LE-Ge detectors low-Z elemental detection is discussed.
The acceptance tests of five electron linear accelerators have been analyzed to compare their completeness, the standards specified by the manufacturers and the measured deviations. Involved tests were relative to geometrical and mechanical parameters, photon and electron beam characteristics, dose monitoring systems, treatment table and safety systems. The comparison of acceptance tests has shown a significant nonuniformity, also due to the absence of a specific legislation; anyway, the measured deviations generally appeared to be within internationally recommended values.
