DSG has completed testing to determine that 92W is more adequate power to achieve 250 degrees Celsius at the<u> front flange</u> of the supermodule. The testing process can be reviewed at the link below.

Next week we will organize a meeting to review the segmentation of a controls system to power 188 supermodules and discuss changes to the prototype heater design to accommodate the segmentation, as well as power supplies.
