Experiment E91-016 "Electroproduction of Kaons
and Light Hypernuclei" (spokespersons Jörg Reinhold, FIU, and Ben
Zeidman, ANL) is scheduled to run in Hall C
from
October 29, 1999 up to December 7, 1999. This experiment is fully compatible
with the base equipment in Hall C. Specifically, the experiment will utilize
the following equipment:
-
Standard Hall C Beam Line: The beam line is identical to
the one used during the previous running periods in 1999 (E96-003, E94-139,
E94-110, E97-006).
-
Hall C Scattering Chamber and Cryotarget system: This experiment
will utilize the cryotarget loops that have been installed during the June
maintenance period. This loops have been operated with hydrogen and deuterium
during the previous running period. In addidion this experiment will make
use of the 3-helium gas system that has been installed in the hall in fall
1997 and successfully been used during experiment E91-003 in spring 1998.
-
Hall C Solid Target System: The experiment uses solid Carbon,
Aluminum and Polyethylene (C-H2) targets which are connected to the Cryotarget.
-
HMS and SOS with their standard detector systems: The SOS
aerogel Cerenkov detector, that has been removed form the detector hut
after the first part of E91-016 and the completion of E93-018, will again
be mounted between the second pair of scintillator planes S2Y and S2X.
The detecor is described in the Hall
C Operating Manual.
-
For none of the kinematical settings with the SOS at an angle
smaller than 20 degree the SOS central momentum will be set to a value
larger than 1.3 GeV/c. Every time the SOS magnets need to be cycled beam
will be requested to be turned off. The magnet control software will independently
verify that there is no beam in the hall before initiating the cycle procedure.
The only modified equipment compared to previous running
periods this year is:
-
The aerogel detector.
-
The 3-helium target gas system
However, both systems have already been operated successfully
on the floor of Hall C during earlier experiments. |
