Energy resolution measurements

 

The following section summarises results obtained from the centre contacts (1=red, 2=green, 3=black 4=blue) of the Super Clover. All measurements were performed with the tex2html_wrap_inline669 source placed 25 cm from the front face of each crystal. The total count rate for each Germanium crystal was 1000 counts per second. We used the ORTEC 572 spectroscopy amplifiers with a shaping time of tex2html_wrap_inline685 . The output pulse from the amplifier was fed into a SILENA ADC 4418/V. The resolution measurements were made using the GOOSY software. Each measurement was made after 10000 counts had been incremented into the peak channel of the tex2html_wrap_inline687 -ray of interest.
