A Time-of-Flight Analyzer Based on a Small On-Line
8-145
Computer

This program enables the computer to interact with the TOF-
converter and to generate spectrum displays on an oscilloscope.
The TOF Converter provides the computer with digital infor-
mation about the time a neutron takes to travel from the
scattering sample to a detector (up to 12 detectors can be
accommodated) and which detector was involved.

The TOF analyzer for which this program was written is in
use with a double chopper facility installed at the ISPRA-I
reactor. It consists of a PDP-8 on-line computer with 4K
memory, the automatic restart option, and a display unit;
a TOF Converter; and conventional counting electronics.
