    keyword=Single Foil Sieve Pattern

    Figure 1 shows the y_tg spectrum for a single foil run taken with sieve slit in. The central foil is easily seen with the Beryllium window upstream. Figure 2 shows the sieve slit pattern at the sieve. Seven rows and columns are easily distinguished.

    r runs. ; This file is read at start of every run. ; Do NOT put spaces in string, NOR add 2nd string. ; The default factor is essentially infinite. ; Keep enough T4 to measure efficiency ; T1 = S1 (or of all paddles) on L-arm. Note, it has after-pulsing. ; T2 = S1.and.Cerenkov on L-arm ; T3 = main single-arm trigger.
