Conclusion: A maximum coil temperature of 50C will keep the hydrocarbon outgassing rate low enough (4e-12 torr-L/s). A conservative coil current limit (based on the vacuum test performed) is 105 mA. Some questionable thermal modeling suggests that for the BOSEMs installed in the top stage of a quad suspension, the coil temperature is likely to be well under this temperature limit, even at a coil drive current of 200 mA. However, measurement of the quad installed BOSEM coil temperature (by measuring coil resistance in situ) is recommended before increasing the coil current higher than 100 mA.
Another similar measurement is planned for L1 ITMy. These results are not yet reported in this memo.
Changes for -v2:
1) Corrected temperature axis label for Figure 3, and switched independent variable to the x-axis.
2) Added clarification on the number of assumed BOSEMs per quad suspension that are likely to be at maximum current.
3) Corrected an error in the last sentence.
