Abstract
One of the key activities during campaign A was a verification of the
Ge and Si anneal heaters. We performed an Si anneal as part of the
standard MIPS-900 Si Startup IER, then we performed another Si anneal
and anneals of the 70um and 160um arrays in MIPS-015. All anneals
executed nominally. We present temperature plots and tables of
minimum and maximum temperatures below.
Analysis
The data from the thermal anneals comes out in binary format, with
filename ce_year-DOYTHH.MM.SS.DDD_0_0_0 or ce_year-DOYTHH.MM.SS.DDD_1_0_0.
I have developed IDL scripts for reading in the files, converting
the telemetry into engineering units, and generating temperature
plots. These files are:
These routines also generate tables of minimum, maximum, and deltas
for all ten temperatures/currents include in the diagnostic anneal
script. The filename for this output file is filename.Temps.
Results
The following are temperature plots and tables of temperatures for
each of the three anneal scripts:
I compared these temperature plots to ground-based test data. The deltaT's
are highly dependent on the MIPS baseplate temperature, so I had to compare
to thermal anneals in the LBTC to make a valid comparison. The general
conclusion is that the shapes and amplitudes of the temperature excursions
are consistent with what we have seen in the past on the ground.
Conclusions
The MIPS thermal anneal heaters are behaving nominally. There have been
no gross changes in the thermal conductances in the area covered by the
MIPS temperature sensors.
