- We have to modify sligtly the design of the radiation shields and establish |
- the knowledge how to produce the radiation shields and how to assemble them. |
- ''As we have actually no replacement parts, the furnace is operational only |
- until the next damage''. |
+ The furnace is back from repair at ''AS Scientific Products Ltd'' and |
+ operational. |
+ The screens are now in a modified design, which allows an easier |
+ replacement of the heater element. But even with this new design, |

+ When heating up the furnace the first time, ramp up slowly, using |
+ the appropriate max. power for the temperature range. The pid values |
+ from a first test (values in parentheses) were not confirm in a later |
