We request a total beam time of one month in the $\pi$E1.2 area. The preferred running period
|
||||
would be to start on October 26. We need at least 14 days free access to
|
||||
the area to mount and commission the experiment. The division of beam time is
|
||||
listed in Table \ref{table:nonlin}.
|
||||
|
||||
The proton measurements use a vacuum chamber which
|
||||
surrounds a thin stopping target and silicon detectors. A germanium detector
|
||||
views the target through a vacuum window. It provides the muon stopping rate
|
||||
in the target by measuring the rate \atrn{2p}{1s} muonic X-rays.
|
||||
|
||||
The gamma and neutron measurements will use a thick target in air,
|
||||
with minimal material near the target. The target has sufficient
|
||||
thickness to fully stop the beam, and will allow an increase of the beam
|
||||
momentum with a subsequent higher stopping rate.
