<div>Hi all,</div>
<div><br>
</div>
<div>I'm happy to report that the 25-elment prototype lead glass
detector has been installed under the Hall B tagger and
everything appears operational. As evidence, I'm attaching a
scope photo. The blue trace is the logic pulse from the trigger
module on the front of the detector. The yellow trace is the
signal from one of the lead glass blocks. You can see a nice
cosmic ray signature: the trigger fires and we also see a PMT
pulse in the lead glass. I'm also attaching a photo of the
setup underneath the tagger.</div>

<div>Many thank to John (F.), Dan, and Kei who carefully packed
all of the detector components at Indiana and made sure
everything was in perfect working order before shipping down
here. It was great to open the toolbox and find every necessary
tool to smoothly complete the installation today. You all made
the job here very easy. Thanks to John (L.), Elton, Ivan, Alex,
and the Hall B techs for their help with the installation this
morning. We're looking forward to a productive run over the
next few months.</div>
