Payload Temperature Changes

J.Torsti presented ERNE's problem: Although all internal heating has been switched off, temperatures of the LED sensor have risen from 25C at the beginning of 1998 to 32C at the beginning of 2001. The maximum operational temperature of the LED surface barrier is 35C according to the manufacturer.

Changing the spacecraft side heaters will affect VIRGO and GOLF, however, and an action item (action 33-1) on the Program Office was established to explore the possibilities of lowering ERNE temperatures with minimal impact to GOLF/VIRGO.
