The configuration of the IBM 1800 data acquisition<br />
and control system has been specified in detail. The<br />
IBM 1800 computer will replace the IBM 1401 at the<br />
beginning of 1968. The new computer system will allow<br />
for on-line data acquisition and supervisory control<br />
of the data collection process. Off-line problems can<br />
be treated in time-sharing. Suitable interface equipment<br />
is under construction.<br />

2.1. Reduction and Analysis of Fission and Scattering Cross<br />
Section <strong>Data</strong><br />
A set of IBM 1401 programs for the reduction of fission<br />
cross section data has been written f"22]. These programs<br />
have been used to process data for<br />
255<br />
^U in the<br />
energy ranges 0.15 ©V - 20 eV and 4 eV - 20 keV, and<br />
for 240 Pu in the energy range 200 eV - 3 keV. 240 Pu<br />
scattering cross section data in the range 20 eV -<br />
1 keV have been processed.<br />
A modified version of programs SMNF 032S (Saclay) for<br />
shape analysis of fission cross section data has been<br />
tested and used to determine resonance parameters of<br />
235<br />
^U in the energy range 6 - 150 eV.<br />
The correlation coefficient between T„ and rv, and the<br />
number of degrees of freedom in the Porter-Thomas<br />
distributions have been calculated with IBM 1401 programs.<br />
Program GACA (General Atomic) for area analysis of<br />
capture cross section data has been modified to be<br />
used for fission data.<br />
A program in French PORTEAN (Saclay) for multiple<br />
scattering and self-absorption corrections has been<br />
rewritten in FORTRAN II, V3 for the IBM 7090 computer.
