Work through runs in order of rows (1 st column). Between each access to change W slabs, cycle through energies in order shown within each row.

#### 23/09 1800 Nig

• time remaining ~80h if no SPS problems
• At previous sample sizes from 22-23/09, we took ~16h to do 20, 40, 60, 80, 100 GeV, and 10 GeV needs ~5h, so to do all 5 remaining thicknesses excluding 10 geV beam would use all remaining time with no spare
• If we drop one sample thickness, perhaps 12W, we can probably get all 20-100 GeV and 1,2,10,14W done.

Misc. other runs:
20007 (60 GeV muon)
20009 (60 GeV hadrons) - no rate
20010 (120 GeV hadrons) - ~ 1kHz
20011 (60 GeV hadrons) - no rate
20012 (120 GeV hadrons with 8W)

#### 26/09   Empty runs    (Tony, John)

20058 (60GeV e+): few events;beam did not return after change of energy (40 to 60GeV)

20059 (40GeV e+): few events - returned from 60 to 40GeV to check that beam was OK, as in the run which had ended a few mins earlier - it was.

#### 25/09 and 26/09  Calibration runs (120GeV hadrons + 0W)         Tony, John
