WBS 1.2.2 Preradiator
Prepared by Toshio Numao Nov. 23, 2004

• Whats in the estimate and whats NOT in the
  estimate.
• Corrections and changes since the last meeting.

2
Whats in the cost estimate?
Material and labor costs for the preradiator
module - Chamber, cables, Readout
electronics, LVHV PSs, DAQ interface,
crates. - Scintillator, WLS fibers, PMTs,
Bases(Preamp w-counting?),
cables(PMT?edge), Readout electronics,
controller, crates. - External PV
(everything). Support structure, Shipping,
Installation
Whats NOT in the cost estimate?

• Racks for PR electronics (Ext.PV cost seems to
  include this).
• Cables for PR scintillators from the edge to the
  readout.?TBI
• LV/HV PSs for PR scintillator.?T.B.Included
• Gain monitor system for PR scint and ExtPV
  systems (New).

3
Changes and Corrections

• WLS fibles now includes waste
  660K ? 1000k
• No. of Ext. PV error in calculation 4x8x45
  1500 ? 1440
• WBS 1.2.2.9 Simulation has been transferred to
  Offline analysis.
• WBS 1.2.2.6 now includes Installation
  oversight.
• 1.2.2.6.1 Pre-installation work the same
  as before (1.2.2.6).
• 1.2.2.6.2 Installation oversight 1.28
  phys, 1.28 eng, 2.56 tech.
• Will introduce a common scaling factor for
  Cdn?US .
• Will include physicists in PR electronics.
• 1.2.2.3.1.3 Anode readout 1.5 phys.
• 1.2.2.3.2.3 Cathode readout 1.5 phys.
• Construction schedule will be updated in a month
  to include more
• details.
