Abstract : The feasibility of measuring transient radiation effects with a radiation hardened recorder, which minimizes ionizing effects on the instrumentation itself, has been investigated by fabricating and testing a 10 channel analog sampling recorder which samples an input signal of + or - 6 ma at a 100 MHZ/s sampling rate for a 100 ns period. The instantaneous sample values are stored as magnetic flux in successive thin magnetic films of a channel. Upon non-destructive readout of the thin films, a time amplitude reconstruction of the input signal is made to within + or - 15% of full scale. The systems shows radiation hardness in excess of 10 to the 10th power r/sec, except for the interface amplifier which is hard to 5 x 10 to the 9th power r/sec. (Author)
