Pion-nucleus total cross section measurements are continuing for pions of 20 to 250 MeV energy. The initial run was made at the low energy pion (LEP) channel of LAMPF. The second run, delayed due to the extended LAMPF shutdown, is scheduled to begin as soon as LAMPF resumes operation of the LEP channel. During the delay the equipment has been modified, the initial data have been reduced and a theoretical analysis of pion-nucleus scattering undertaken. The cross sections are measured with the usual attenuation method. A DISC counter identifies the pions for energies above 65 MeV and time of flight counters gated with an r.f. signal from the accelerator identifies the incident pions at lower energies. Data are presented from measurements made during the initial run. They include cross sections from measurements on /sup 4/He between 25 and 105 MeV, on isotope sets (/sup 12/C, /sup 13/C) (O/sup 16/, /sup 18/O) (/sup 40/Ca, /sup 44/Ca, /sup 48/Ca) between 85 and 200 MeV and on 18 nuclei with 4 < A < 208 MeV. The statistical precision was 2 to 3% for the first run. The statistical accuracy is to be improved and additional targets of /sup 6/Li, /sup 7/Li, /sup 10/B, /sup 11/B and Sc utilized during the second run.
