4. HISTORICAL BACKGROUND AND INFORMATION

A heavy charged-particle recoil data base [primary knock-on atom (PKA) spectra] and an analysis program were created to assist experimentalists in studying, evaluating, and correlating radiation-damage effects in different neutron environments.

5. APPLICATION OF THE DATA

Since experimentally obtained controlled-thermonuclear-reactor-type neutron spectra are not presently available, the data base can be extremely useful in relating currently obtainable radiation damage to that which is anticipated in future fusion devices.

6. SOURCE AND SCOPE OF DATA

Most of the elements of interest to the radiation-damage community and all neutron reactions of any significance for these elements have been processed using available ENDF/B-IV cross section data. These are included in the data base. Calculated data such as primary recoil spectra, displacement rates, and gas-production rates, obtained with the data base for different radiation environments, are presented and compared with previous calculations. The elements used by DLC-55/RECOIL are:

W, 11B, Nb, Ni, Cr, Fe, Al, Si, V, Mn, Co, 6Li, 7Li, 10B, C, N, Mg, Au, Zr, Ta, Ti, Mo, Pb, Be, Cu, O.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM

RECOIL can be run when the group boundaries and appropriate recoil spectra data have been run through their respective programs. The recoil spectra for a given material is expected to be found on a particular logical unit which is built into the Fortran logic of the RECOIL program.

8. DATA FORMAT AND COMPUTER
