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 18 th 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.
