Hall-D Open House Important Info:

Volunteers
-------------------
We should have between 7 and 17 volunteers at any given time
spread between the counting house and Hall-D itself. I screen
captured the volunteer list some time ago and it is below to remind
yourself of which shift you signed up for.


Visitor Traffic Pattern
-------------------------------
Visitors  will either walk to or be dropped off with golf carts at the 
counting
house.

 From the counting house they will go downstairs into Hall-D.

We should try and direct them to leave Hall-D through the truck ramp
and walk back around to the counting house parking lot.

If anyone has difficulty getting down the stairs or up the truck ramp, Tom
will have a golf cart available that can drive them up and down the truck
ramp. We can't use that for everyone though since it is battery powered.


Stations
-------------------------------
There are multiple stations set up in the Hall and counting house. The
plan is to have you all self-assign yourself to a station. For some of you,
it will be obvious where you should be. You may also roam around to
try and help wherever visitors may be. Here is a list of stations:

- Counting House:
      We need between 2 and 4 volunteers here at any point in time. At 
least
      one should be a physicist. They should be able to describe the GlueX
      experiment, show them the rack room, and generally "prime" visitors
      for what they will be seeing in the hall.

- Entrance to Hall:
      This is option if we have enough volunteers on hand. There are 2 
physics
      posters they will see as they enter the hall that the volunteer 
can speak
      to and then point them to the other stations

- Event display on side of magnet
     Self-explanatory. Note that this is a movie so the display is not
     interactive.

- FDC display on platform
      FDC experts preferred here.

- BCAL modules on platform
      Need one person on either side. Make sure nobody touches the modules
     due to the exposed lead hazard! Also, people may be tempted to try
     and yank off a stray fiber. Don't let them do it!. We will have a 
laser on hand
     to shine through. One can also place a cell phone next to the 
plexiglass on
     either end, but the effect is not terribly dramatic due to the 
plexiglass.

- Collimator cave
     There is one poster near where the beam enters the hall. It has 
diagrams of
     the tagger building and can be used to talk a little about the beam.

- mini-BCAL/mini-FCAL
     These are on a table at ground level on the same side of the hall 
as the
     truck ramp.

- SiPM/light guide/PMT table (under platform)
     Opposite of the mini-detectors is a table with some readout devices.

- Civil Construction (truck ramp)
      Some posters showing the civil construction. This volunteer should 
also
      point the visitors to the way back to the counting house parking lot.


Cell-Phone
-----------------------------
We have one cell-phone for both the counting house and Hall-D.
It will be kept by one of the volunteers in the counting house. A list
of important numbers will be kept with the phone. If you need to contact
Open house organizers for any reason, get the phone from the
person in the counting house.


Accidental Power shutdown
------------------------------
There are emergency STOP buttons in the counting house and Hall
that someone may accidentally press. If this happens, you will need to
call either Mark Stevens (757-903-9773) or Mark Bear (757-952-5121)
(or is it 757-592-5121?). They have keys and knowledge to get the
breakers turned back on.


Snacks
-------------------------
Snacks for volunteers will be available in the dumb waiter. When you are
done, make sure you close the doors of the dumb waiter so the person
on the other end may call it if desired.


Questions can be referred to David Lawrence (cell 757-746-6697).
