The scheme of using a pair of fast-response thermistors to measure CT^2 works well. The hardware implementation needs an iteration.
Issues include:
1. thermistors are exposed and subject to damage. Needs a low-obscuration protective screen.
2. circuit implementation is unacceptable. Plugboards and wiring and data acq unit are rattling around, unmounted, in box. OK for test setup but not as a final version.
3. There are tens of degrees of vertical temperature gradient in the dome. Need a local determination of temperature to get from voltage differences to temperature differences.
Good end-cap screen:
