Measurement of the monitored drift tubes response to energetic neutrons

We have measured the response of an array of monitored drift tubes (MDT) to fast neutrons produced by a t(d, n)/sup 4/He reaction at the Tandem Van de Graaff accelerator of the National Center of Scientific Research (NCSR) "Demokritos". The MDT setup consisted of 24 drift tubes operating w...

Sumario:We have measured the response of an array of monitored drift tubes (MDT) to fast neutrons produced by a t(d, n)/sup 4/He reaction at the Tandem Van de Graaff accelerator of the National Center of Scientific Research (NCSR) "Demokritos". The MDT setup consisted of 24 drift tubes operating with a gas mixture of ArCO/sub 2/ (93:7%) at 3 bar absolute pressure. The neutron energy was 18.3 MeV. The operating anode wire voltage varied from 2200 V to 2800 V. The PC based data acquisition system was self-triggered by the OR of all 24 MDT. Data were also taken by triggering on a single tube. The data analysis is presented and the response of the MDT detector to energetic neutrons is discussed with emphasis on the determination of the MDT sensitivity to neutrons. (5 refs).
