Descopes

• Build only 16 or 17 flight towers?
• Tower-0 used up a lot of flight material that we
  have to replace if we want to build the 18th
  tower.
• We are having yield problems with other parts, in
  particular the MCMs.
• This potentially could require painful actions
  such as making more ASICs in order to built 18
  more towers.
• We are already going out to purchase more
  long-lead material such as the carbon-carbon for
  tray fabrication, and we are considering building
  more bottom-tray closeouts (all U.S. expense).
• Tower-0 probably could be refitted to make an
  acceptable beam-test tower by replacing or
  reworking the layers that are dead using good,
  but non-flight parts.
• Such a beam-test tower would not require
  environmental testing, resulting in some more
  savings.
