COMPASSCOMPASS beam-schedule

for the period

May 25 - September 9, 2000

M2 / EHN2 / 888

This is the provisional schedule as of May 9, 2000

Beam activities in 2000:

Period beam priorities remarks
May 25 - May 30 muons beam setup
May 30 MD, electrons electron beam test (L. Gatignon, S. Donskov, A. Olchevski)
May 31 - June 7 muons MWPC tests (O. Denisov)
electron beam test vs. MWPC tests
(to be confirmed)
June 7 MD
June 7 - June 19 muons muon trigger studies (June 10 - June 19)
June 19 - June 23 no beam installations area open
June 23 - July 5 electrons 1 week ECAL calibration
1 week hadron beam tests with (S. Donskov, A. Olchevski)
ECAL and target veto
June 28 , July 5 MD
July 5 - July 31 muons
July 12 MD SPS energy change from 450 GeV to 400 GeV
July 19 - July 20 MD
July 26 MD
July 31 - August 4 no beam installations area open
August 4 - September 4 muons 2 weeks muon trigger studies (F. Klein, D. v. Harrach)
with MWPC-B equipped
2 weeks RICH studies (S. dalla Torre)
with MWPC-A equipped
September 4 - September 9 muons low-rate only

About the beam conditions:

Before July 12 we will have 5*1012 protons of 450 GeV from the SPS, sufficient for 108 muons
at 160 GeV per spill, spill length about 2 sec. If more rate is needed, one can tune the muon-beam
to lower energies.
After July 12 we will have 1013 protons of 400 GeV per spill, spill length about 3 sec, sufficient
for 2*108 muons per spill.
