BNL Detector team status report, June 24, 1996

We took beam in the ring last Thursday night,
then removed all detectors from the ring
on Friday in anticipation of turning on the magnet.

Magnet powering efforts will be under way this week. Once
things have stabilized, we would like to put at least a detector at 90 degrees
to check the effect of B-field.

In the Thursday beam tests, we took runs with both pion and muon 'injection',
no magnet, simulated inflector.

A lithium sheet was placed in front of the FSD/PSD on station #2. Lithium
is already between the FSD and the calorimeter. We wanted to test
if this would cut the 'neutron' spikes in the FSD. The primary beam
is not hitting calorimeter #2 directly, so we thought that most of the noise
in the FSDs must be due to slow neutrons from the steel. This ought to be
stopped by the lithium sheet if they are thermalized.

One of the calorimeter signals and one of the FSD signals on station #1
was clipped,
and the DC level of the corresponding WFDs was offset so that we could see the
negative overshoots.

We also did a run with all four elements of calormeter #1 summed- note that one
of the tubes was clipped however.
