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 32
C at the beginning of 2001.
The maximum operational temperature of the LED surface barrier is
35
C 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.
