Richard Jones (Ictij and Aianin \\ arren (right), two members of our team from Los Alamos, 

 use the special fork lift to insert the top target tank into the detector shield at the Sa- 

 vannah River Plant reactor. Heavy lead doors behind Warren move by hydraulic 

 control to cover the detector when it is operated. A rack of preamplifiers are seen behind 

 Jones. These amplified the small voltage pulses obtained from the tubes and sent them 

 through coaxial cables to the electronics trailer parked outside the reactor building.
