| - * The automatic needle valve control does not work properly. It seems that this |
| - is a mechanical problem. The magnet was sent back to |
| - Oxford Instruments and should be back in the beginning of May 2005. |
| - |
| - * The rotatable sample stick has a relatively bad thermal contact. Therefore the |
| - minimal sample temperature is increased. It is not sure if putting more |
| - exchange gas can elimate this problem. |
| + * The automatic needle valve does not always work properly. |
| + A mechanical problem was solved by Oxford Instruments. |
| + It is still a problem that sometimes the needle valve bar |
| + gets frozen. This problem might be avoided when keeping warm |
| + the top of the needle valve during fill. However, at high |
| + fields, the air dryer might not work! |
| + |
| + * The nitrogen level gauge does not work. This has to be fixed, but |
| + it seems that it may appear often. |
| At line 33 added 3 lines. |
| + * During He-fill, LN2 has to be filled again in order to avoid |
| + air sucking into the LN2 dewar. |
