Assembly and testing of ATIC continues to go well.
Much of the SIP integration has been completed and we have
verified the TDRSS high rate, TDRSS low rate and LOS communication
links. A remaining task is
to verify the COM2 Iridium link.
In addition, the upper external
structure has been assembled and flight antennas have been installed.
Flight preparation of the Silicon Matrix (SiM) has also proceeded well.
On Tuesday, Oct 30, the remaining MSFC personnel (Christl) arrived on
the ice and, in addition, the matrix was placed on the ATIC detector
stack to evaluate its performance during the nightly muon run.
Analysis of these data the following day showed that the SiM is
performing well with the exception of one problem detector card.
This problem was resolved during the day Wednesday and the SiM
was hard mounted to ATIC in its flight position.
Preliminary analysis of the Wednesday night muon data today,
shows that all major issues on the SiM have
been resolved. A remaining
task is to verify muon signals in all of the matrix pixels.
Final preparation of ATIC for installing the pressure shells is
currently underway. This
involves locking connectors, wrapping cables and installing the pressure
bladder protection padding and mesh.
